+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+  as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install accepts
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch (accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+# After [![Build Status][1]][2]
+
+Invoke callback after n calls
+
+## Status: production ready
+
+## Example
+
+```js
+var after = require("after")
+var db = require("./db") // some db.
+
+var updateUser = function (req, res) {
+  // use after to run two tasks in parallel,
+  // namely get request body and get session
+  // then run updateUser with the results
+  var next = after(2, updateUser)
+  var results = {}
+  
+  getJSONBody(req, res, function (err, body) {
+    if (err) return next(err)
+    
+    results.body = body
+    next(null, results)
+  })
+  
+  getSessionUser(req, res, function (err, user) {
+    if (err) return next(err)
+    
+    results.user = user
+    next(null, results)
+  })
+  
+  // now do the thing!
+  function updateUser(err, result) {
+    if (err) {
+      res.statusCode = 500
+      return res.end("Unexpected Error")
+    }
+    
+    if (!result.user || result.user.role !== "admin") {
+      res.statusCode = 403
+      return res.end("Permission Denied")
+    }
+    
+    db.put("users:" + req.params.userId, result.body, function (err) {
+      if (err) {
+        res.statusCode = 500
+        return res.end("Unexpected Error")
+      }
+      
+      res.statusCode = 200
+      res.end("Ok")  
+    })   
+  }
+}
+```
+
+## Naive Example
+
+```js
+var after = require("after")
+    , next = after(3, logItWorks)
+
+next()
+next()
+next() // it works
+
+function logItWorks() {
+    console.log("it works!")
+}
+```
+
+## Example with error handling
+
+```js
+var after = require("after")
+    , next = after(3, logError)
+
+next()
+next(new Error("oops")) // logs oops
+next() // does nothing
+
+// This callback is only called once.
+// If there is an error the callback gets called immediately
+// this avoids the situation where errors get lost.
+function logError(err) {
+    console.log(err)
+}
+```

+# Async-Limiter
+
+A module for limiting concurrent asynchronous actions in flight. Forked from [queue](https://github.com/jessetane/queue).
+
+[![npm](http://img.shields.io/npm/v/async-limiter.svg?style=flat-square)](http://www.npmjs.org/async-limiter)
+[![tests](https://img.shields.io/travis/STRML/async-limiter.svg?style=flat-square&branch=master)](https://travis-ci.org/STRML/async-limiter)
+[![coverage](https://img.shields.io/coveralls/STRML/async-limiter.svg?style=flat-square&branch=master)](https://coveralls.io/r/STRML/async-limiter)
+
+This module exports a class `Limiter` that implements some of the `Array` API.
+Pass async functions (ones that accept a callback or return a promise) to an instance's additive array methods.
+
+## Motivation
+
+Certain functions, like `zlib`, have [undesirable behavior](https://github.com/nodejs/node/issues/8871#issuecomment-250915913) when
+run at infinite concurrency.
+
+In this case, it is actually faster, and takes far less memory, to limit concurrency.
+
+This module should do the absolute minimum work necessary to queue up functions. PRs are welcome that would
+make this module faster or lighter, but new functionality is not desired.
+
+Style should confirm to nodejs/node style.
+
+## Example
+
+``` javascript
+var Limiter = require('async-limiter')
+
+var t = new Limiter({concurrency: 2});
+var results = []
+
+// add jobs using the familiar Array API
+t.push(function (cb) {
+  results.push('two')
+  cb()
+})
+
+t.push(
+  function (cb) {
+    results.push('four')
+    cb()
+  },
+  function (cb) {
+    results.push('five')
+    cb()
+  }
+)
+
+t.unshift(function (cb) {
+  results.push('one')
+  cb()
+})
+
+t.splice(2, 0, function (cb) {
+  results.push('three')
+  cb()
+})
+
+// Jobs run automatically. If you want a callback when all are done,
+// call 'onDone()'.
+t.onDone(function () {
+  console.log('all done:', results)
+})
+```
+
+## Zlib Example
+
+```js
+const zlib = require('zlib');
+const Limiter = require('async-limiter');
+
+const message = {some: "data"};
+const payload = new Buffer(JSON.stringify(message));
+
+// Try with different concurrency values to see how this actually
+// slows significantly with higher concurrency!
+//
+// 5:        1398.607ms
+// 10:       1375.668ms
+// Infinity: 4423.300ms
+//
+const t = new Limiter({concurrency: 5});
+function deflate(payload, cb) {
+  t.push(function(done) {
+    zlib.deflate(payload, function(err, buffer) {
+      done();
+      cb(err, buffer);
+    });
+  });
+}
+
+console.time('deflate');
+for(let i = 0; i < 30000; ++i) {
+  deflate(payload, function (err, buffer) {});
+}
+q.onDone(function() {
+  console.timeEnd('deflate');
+});
+```
+
+## Install
+
+`npm install async-limiter`
+
+## Test
+
+`npm test`
+
+## API
+
+### `var t = new Limiter([opts])`
+Constructor. `opts` may contain inital values for:
+* `q.concurrency`
+
+## Instance methods
+
+### `q.onDone(fn)`
+`fn` will be called once and only once, when the queue is empty.
+
+## Instance methods mixed in from `Array`
+Mozilla has docs on how these methods work [here](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array).
+### `q.push(element1, ..., elementN)`
+### `q.unshift(element1, ..., elementN)`
+### `q.splice(index , howMany[, element1[, ...[, elementN]]])`
+
+## Properties
+### `q.concurrency`
+Max number of jobs the queue should process concurrently, defaults to `Infinity`.
+
+### `q.length`

+
+
+Async is a utility module which provides straight-forward, powerful functions
+for working with asynchronous JavaScript. Although originally designed for
+use with [Node.js](http://nodejs.org) and installable via `npm install async`,
+it can also be used directly in the browser.
+
+Async is also installable via:
+
+- [bower](http://bower.io/): `bower install async`
+- [component](https://github.com/component/component): `component install
+  caolan/async`
+- [jam](http://jamjs.org/): `jam install async`
+- [spm](http://spmjs.io/): `spm install async`
+
+Async provides around 20 functions that include the usual 'functional'
+suspects (`map`, `reduce`, `filter`, `each`…) as well as some common patterns
+for asynchronous control flow (`parallel`, `series`, `waterfall`…). All these
+functions assume you follow the Node.js convention of providing a single
+callback as the last argument of your `async` function.
+
+
+## Quick Examples
+
+```javascript
+async.map(['file1','file2','file3'], fs.stat, function(err, results){
+    // results is now an array of stats for each file
+});
+
+async.filter(['file1','file2','file3'], fs.exists, function(results){
+    // results now equals an array of the existing files
+});
+
+async.parallel([
+    function(){ ... },
+    function(){ ... }
+], callback);
+
+async.series([
+    function(){ ... },
+    function(){ ... }
+]);
+```
+
+There are many more functions available so take a look at the docs below for a
+full list. This module aims to be comprehensive, so if you feel anything is
+missing please create a GitHub issue for it.
+
+## Common Pitfalls <sub>[(StackOverflow)](http://stackoverflow.com/questions/tagged/async.js)</sub>
+### Synchronous iteration functions
+
+If you get an error like `RangeError: Maximum call stack size exceeded.` or other stack overflow issues when using async, you are likely using a synchronous iterator.  By *synchronous* we mean a function that calls its callback on the same tick in the javascript event loop, without doing any I/O or using any timers.  Calling many callbacks iteratively will quickly overflow the stack. If you run into this issue, just defer your callback with `async.setImmediate` to start a new call stack on the next tick of the event loop.
+
+This can also arise by accident if you callback early in certain cases:
+
+```js
+async.eachSeries(hugeArray, function iterator(item, callback) {
+  if (inCache(item)) {
+    callback(null, cache[item]); // if many items are cached, you'll overflow
+  } else {
+    doSomeIO(item, callback);
+  }
+}, function done() {
+  //...
+});
+```
+
+Just change it to:
+
+```js
+async.eachSeries(hugeArray, function iterator(item, callback) {
+  if (inCache(item)) {
+    async.setImmediate(function () {
+      callback(null, cache[item]);
+    });
+  } else {
+    doSomeIO(item, callback);
+  //...
+```
+
+Async guards against synchronous functions in some, but not all, cases.  If you are still running into stack overflows, you can defer as suggested above, or wrap functions with [`async.ensureAsync`](#ensureAsync)  Functions that are asynchronous by their nature do not have this problem and don't need the extra callback deferral.
+
+If JavaScript's event loop is still a bit nebulous, check out [this article](http://blog.carbonfive.com/2013/10/27/the-javascript-event-loop-explained/) or [this talk](http://2014.jsconf.eu/speakers/philip-roberts-what-the-heck-is-the-event-loop-anyway.html) for more detailed information about how it works.
+
+
+### Multiple callbacks
+
+Make sure to always `return` when calling a callback early, otherwise you will cause multiple callbacks and unpredictable behavior in many cases.
+
+```js
+async.waterfall([
+    function (callback) {
+        getSomething(options, function (err, result) {
+          if (err) {
+            callback(new Error("failed getting something:" + err.message));
+            // we should return here
+          }
+          // since we did not return, this callback still will be called and
+          // `processData` will be called twice
+          callback(null, result);
+        });
+    },
+    processData
+], done)
+```
+
+It is always good practice to `return callback(err, result)`  whenever a callback call is not the last statement of a function.
+
+
+### Binding a context to an iterator
+
+This section is really about `bind`, not about `async`. If you are wondering how to
+make `async` execute your iterators in a given context, or are confused as to why
+a method of another library isn't working as an iterator, study this example:
+
+```js
+// Here is a simple object with an (unnecessarily roundabout) squaring method
+var AsyncSquaringLibrary = {
+  squareExponent: 2,
+  square: function(number, callback){
+    var result = Math.pow(number, this.squareExponent);
+    setTimeout(function(){
+      callback(null, result);
+    }, 200);
+  }
+};
+
+async.map([1, 2, 3], AsyncSquaringLibrary.square, function(err, result){
+  // result is [NaN, NaN, NaN]
+  // This fails because the `this.squareExponent` expression in the square
+  // function is not evaluated in the context of AsyncSquaringLibrary, and is
+  // therefore undefined.
+});
+
+async.map([1, 2, 3], AsyncSquaringLibrary.square.bind(AsyncSquaringLibrary), function(err, result){
+  // result is [1, 4, 9]
+  // With the help of bind we can attach a context to the iterator before
+  // passing it to async. Now the square function will be executed in its
+  // 'home' AsyncSquaringLibrary context and the value of `this.squareExponent`
+  // will be as expected.
+});
+```

+## Collections
+
+<a name="forEach" />
+<a name="each" />
+### each(arr, iterator, [callback])
+
+Applies the function `iterator` to each item in `arr`, in parallel.
+The `iterator` is called with an item from the list, and a callback for when it
+has finished. If the `iterator` passes an error to its `callback`, the main
+`callback` (for the `each` function) is immediately called with the error.
+
+Note, that since this function applies `iterator` to each item in parallel,
+there is no guarantee that the iterator functions will complete in order.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A function to apply to each item in `arr`.
+  The iterator is passed a `callback(err)` which must be called once it has
+  completed. If no error has occurred, the `callback` should be run without
+  arguments or with an explicit `null` argument.  The array index is not passed
+  to the iterator.  If you need the index, use [`forEachOf`](#forEachOf).
+* `callback(err)` - *Optional* A callback which is called when all `iterator` functions
+  have finished, or an error occurs.
+
+__Examples__
+
+
+```js
+// assuming openFiles is an array of file names and saveFile is a function
+// to save the modified contents of that file:
+
+async.each(openFiles, saveFile, function(err){
+    // if any of the saves produced an error, err would equal that error
+});
+```
+
+```js
+// assuming openFiles is an array of file names
+
+async.each(openFiles, function(file, callback) {
+
+  // Perform operation on file here.
+  console.log('Processing file ' + file);
+
+  if( file.length > 32 ) {
+    console.log('This file name is too long');
+    callback('File name too long');
+  } else {
+    // Do work to process file here
+    console.log('File processed');
+    callback();
+  }
+}, function(err){
+    // if any of the file processing produced an error, err would equal that error
+    if( err ) {
+      // One of the iterations produced an error.
+      // All processing will now stop.
+      console.log('A file failed to process');
+    } else {
+      console.log('All files have been processed successfully');
+    }
+});

+
+### forEachOf(obj, iterator, [callback])
+
+Like `each`, except that it iterates over objects, and passes the key as the second argument to the iterator.
+
+__Arguments__
+
+* `obj` - An object or array to iterate over.
+* `iterator(item, key, callback)` - A function to apply to each item in `obj`.
+The `key` is the item's key, or index in the case of an array. The iterator is
+passed a `callback(err)` which must be called once it has completed. If no
+error has occurred, the callback should be run without arguments or with an
+explicit `null` argument.
+* `callback(err)` - *Optional* A callback which is called when all `iterator` functions have finished, or an error occurs.
+
+__Example__
+
+```js
+var obj = {dev: "/dev.json", test: "/test.json", prod: "/prod.json"};
+var configs = {};
+
+async.forEachOf(obj, function (value, key, callback) {
+  fs.readFile(__dirname + value, "utf8", function (err, data) {
+    if (err) return callback(err);
+    try {
+      configs[key] = JSON.parse(data);
+    } catch (e) {
+      return callback(e);
+    }
+    callback();
+  })
+}, function (err) {
+  if (err) console.error(err.message);
+  // configs is now a map of JSON data
+  doSomethingWith(configs);
+})

+
+<a name="map" />
+### map(arr, iterator, [callback])
+
+Produces a new array of values by mapping each value in `arr` through
+the `iterator` function. The `iterator` is called with an item from `arr` and a
+callback for when it has finished processing. Each of these callback takes 2 arguments:
+an `error`, and the transformed item from `arr`. If `iterator` passes an error to its
+callback, the main `callback` (for the `map` function) is immediately called with the error.
+
+Note, that since this function applies the `iterator` to each item in parallel,
+there is no guarantee that the `iterator` functions will complete in order.
+However, the results array will be in the same order as the original `arr`.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A function to apply to each item in `arr`.
+  The iterator is passed a `callback(err, transformed)` which must be called once
+  it has completed with an error (which can be `null`) and a transformed item.
+* `callback(err, results)` - *Optional* A callback which is called when all `iterator`
+  functions have finished, or an error occurs. Results is an array of the
+  transformed items from the `arr`.
+
+__Example__
+
+```js
+async.map(['file1','file2','file3'], fs.stat, function(err, results){
+    // results is now an array of stats for each file
+});
+```

+---------------------------------------
+
+<a name="select" />
+<a name="filter" />
+### filter(arr, iterator, [callback])
+
+__Alias:__ `select`
+
+Returns a new array of all the values in `arr` which pass an async truth test.
+_The callback for each `iterator` call only accepts a single argument of `true` or
+`false`; it does not accept an error argument first!_ This is in-line with the
+way node libraries work with truth tests like `fs.exists`. This operation is
+performed in parallel, but the results array will be in the same order as the
+original.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A truth test to apply to each item in `arr`.
+  The `iterator` is passed a `callback(truthValue)`, which must be called with a
+  boolean argument once it has completed.
+* `callback(results)` - *Optional* A callback which is called after all the `iterator`
+  functions have finished.
+
+__Example__
+
+```js
+async.filter(['file1','file2','file3'], fs.exists, function(results){
+    // results now equals an array of the existing files
+});
+```

+### reject(arr, iterator, [callback])
+
+The opposite of [`filter`](#filter). Removes values that pass an `async` truth test.

+* rejectSeries(arr, iterator, [callback])
+* rejectLimit(arr, limit, iterator, [callback])
+
+---------------------------------------
+
+<a name="reduce" />
+### reduce(arr, memo, iterator, [callback])
+
+__Aliases:__ `inject`, `foldl`
+
+Reduces `arr` into a single value using an async `iterator` to return
+each successive step. `memo` is the initial state of the reduction.
+This function only operates in series.
+
+For performance reasons, it may make sense to split a call to this function into
+a parallel map, and then use the normal `Array.prototype.reduce` on the results.
+This function is for situations where each step in the reduction needs to be async;
+if you can get the data before reducing it, then it's probably a good idea to do so.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `memo` - The initial state of the reduction.
+* `iterator(memo, item, callback)` - A function applied to each item in the
+  array to produce the next step in the reduction. The `iterator` is passed a
+  `callback(err, reduction)` which accepts an optional error as its first
+  argument, and the state of the reduction as the second. If an error is
+  passed to the callback, the reduction is stopped and the main `callback` is
+  immediately called with the error.
+* `callback(err, result)` - *Optional* A callback which is called after all the `iterator`
+  functions have finished. Result is the reduced value.
+
+__Example__
+
+```js
+async.reduce([1,2,3], 0, function(memo, item, callback){
+    // pointless async:
+    process.nextTick(function(){
+        callback(null, memo + item)
+    });
+}, function(err, result){
+    // result is now equal to the last value of memo, which is 6
+});

+
+<a name="detect" />
+### detect(arr, iterator, [callback])
+
+Returns the first value in `arr` that passes an async truth test. The
+`iterator` is applied in parallel, meaning the first iterator to return `true` will
+fire the detect `callback` with that result. That means the result might not be
+the first item in the original `arr` (in terms of order) that passes the test.
+
+If order within the original `arr` is important, then look at [`detectSeries`](#detectSeries).
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A truth test to apply to each item in `arr`.
+  The iterator is passed a `callback(truthValue)` which must be called with a
+  boolean argument once it has completed. **Note: this callback does not take an error as its first argument.**
+* `callback(result)` - *Optional* A callback which is called as soon as any iterator returns
+  `true`, or after all the `iterator` functions have finished. Result will be
+  the first item in the array that passes the truth test (iterator) or the
+  value `undefined` if none passed.  **Note: this callback does not take an error as its first argument.**
+
+__Example__

+    // result now equals the first file in the list that exists

+### sortBy(arr, iterator, [callback])
+
+Sorts a list by the results of running each `arr` value through an async `iterator`.
+
+__Arguments__
+
+* `arr` - An array to iterate over.
+* `iterator(item, callback)` - A function to apply to each item in `arr`.
+  The iterator is passed a `callback(err, sortValue)` which must be called once it
+  has completed with an error (which can be `null`) and a value to use as the sort
+  criteria.
+* `callback(err, results)` - *Optional* A callback which is called after all the `iterator`
+  functions have finished, or an error occurs. Results is the items from
+  the original `arr` sorted by the values returned by the `iterator` calls.
+
+__Example__
+
+```js
+async.sortBy(['file1','file2','file3'], function(file, callback){

+<a name="series" />
+### series(tasks, [callback])
+
+Run the functions in the `tasks` array in series, each one running once the previous
+function has completed. If any functions in the series pass an error to its
+callback, no more functions are run, and `callback` is immediately called with the value of the error.
+Otherwise, `callback` receives an array of results when `tasks` have completed.
+
+It is also possible to use an object instead of an array. Each property will be
+run as a function, and the results will be passed to the final `callback` as an object
+instead of an array. This can be a more readable way of handling results from

+
+**Note** that while many implementations preserve the order of object properties, the
+[ECMAScript Language Specification](http://www.ecma-international.org/ecma-262/5.1/#sec-8.6)
+explicitly states that
+
+> The mechanics and order of enumerating the properties is not specified.
+
+So if you rely on the order in which your series of functions are executed, and want
+this to work on all platforms, consider using an array.
+
+__Arguments__
+
+* `tasks` - An array or object containing functions to run, each function is passed
+  a `callback(err, result)` it must call on completion with an error `err` (which can
+  be `null`) and an optional `result` value.
+* `callback(err, results)` - An optional callback to run once all the functions
+  have completed. This function gets a results array (or object) containing all
+  the result arguments passed to the `task` callbacks.
+
+__Example__

+### parallel(tasks, [callback])
+
+Run the `tasks` array of functions in parallel, without waiting until the previous

+callback, the main `callback` is immediately called with the value of the error.
+Once the `tasks` have completed, the results are passed to the final `callback` as an
+array.
+
+**Note:** `parallel` is about kicking-off I/O tasks in parallel, not about parallel execution of code.  If your tasks do not use any timers or perform any I/O, they will actually be executed in series.  Any synchronous setup sections for each task will happen one after the other.  JavaScript remains single-threaded.
+
+It is also possible to use an object instead of an array. Each property will be
+run as a function and the results will be passed to the final `callback` as an object
+instead of an array. This can be a more readable way of handling results from

+* `tasks` - An array or object containing functions to run. Each function is passed
+  a `callback(err, result)` which it must call on completion with an error `err`
+  (which can be `null`) and an optional `result` value.
+* `callback(err, results)` - An optional callback to run once all the functions
+  have completed successfully. This function gets a results array (or object) containing all
+  the result arguments passed to the task callbacks.
+
+__Example__

+<a name="queue" />
+### queue(worker, [concurrency])
+
+Creates a `queue` object with the specified `concurrency`. Tasks added to the
+`queue` are processed in parallel (up to the `concurrency` limit). If all
+`worker`s are in progress, the task is queued until one becomes available.
+Once a `worker` completes a `task`, that `task`'s callback is called.
+
+__Arguments__
+
+* `worker(task, callback)` - An asynchronous function for processing a queued
+  task, which must call its `callback(err)` argument when finished, with an
+  optional `error` as an argument.  If you want to handle errors from an individual task, pass a callback to `q.push()`.
+* `concurrency` - An `integer` for determining how many `worker` functions should be
+  run in parallel.  If omitted, the concurrency defaults to `1`.  If the concurrency is `0`, an error is thrown.
+
+__Queue objects__
+
+The `queue` object returned by this function has the following properties and
+methods:
+
+* `length()` - a function returning the number of items waiting to be processed.
+* `started` - a function returning whether or not any items have been pushed and processed by the queue
+* `running()` - a function returning the number of items currently being processed.
+* `workersList()` - a function returning the array of items currently being processed.
+* `idle()` - a function returning false if there are items waiting or being processed, or true if not.
+* `concurrency` - an integer for determining how many `worker` functions should be
+  run in parallel. This property can be changed after a `queue` is created to
+  alter the concurrency on-the-fly.
+* `push(task, [callback])` - add a new task to the `queue`. Calls `callback` once
+  the `worker` has finished processing the task. Instead of a single task, a `tasks` array
+  can be submitted. The respective callback is used for every task in the list.
+* `unshift(task, [callback])` - add a new task to the front of the `queue`.
+* `saturated` - a callback that is called when the `queue` length hits the `concurrency` limit,
+   and further tasks will be queued.
+* `empty` - a callback that is called when the last item from the `queue` is given to a `worker`.
+* `drain` - a callback that is called when the last item from the `queue` has returned from the `worker`.
+* `paused` - a boolean for determining whether the queue is in a paused state
+* `pause()` - a function that pauses the processing of tasks until `resume()` is called.
+* `resume()` - a function that resumes the processing of queued tasks when the queue is paused.
+* `kill()` - a function that removes the `drain` callback and empties remaining tasks from the queue forcing it to go idle.
+
+__Example__
+
+```js
+// create a queue object with concurrency 2
+
+var q = async.queue(function (task, callback) {
+    console.log('hello ' + task.name);
+    callback();
+}, 2);
+
+
+// assign a callback
+q.drain = function() {
+    console.log('all items have been processed');
+}
+
+// add some items to the queue
+
+q.push({name: 'foo'}, function (err) {
+    console.log('finished processing foo');
+});
+q.push({name: 'bar'}, function (err) {
+    console.log('finished processing bar');
+});
+
+// add some items to the queue (batch-wise)
+
+q.push([{name: 'baz'},{name: 'bay'},{name: 'bax'}], function (err) {
+    console.log('finished processing item');
+});
+
+// add some items to the front of the queue
+
+q.unshift({name: 'bar'}, function (err) {
+    console.log('finished processing bar');
+});
+```

+
+<a name="priorityQueue" />
+### priorityQueue(worker, concurrency)
+
+The same as [`queue`](#queue) only tasks are assigned a priority and completed in ascending priority order. There are two differences between `queue` and `priorityQueue` objects:
+
+* `push(task, priority, [callback])` - `priority` should be a number. If an array of
+  `tasks` is given, all tasks will be assigned the same priority.
+* The `unshift` method was removed.
+
+---------------------------------------
+
+<a name="cargo" />
+### cargo(worker, [payload])
+
+Creates a `cargo` object with the specified payload. Tasks added to the
+cargo will be processed altogether (up to the `payload` limit). If the
+`worker` is in progress, the task is queued until it becomes available. Once
+the `worker` has completed some tasks, each callback of those tasks is called.
+Check out [these](https://camo.githubusercontent.com/6bbd36f4cf5b35a0f11a96dcd2e97711ffc2fb37/68747470733a2f2f662e636c6f75642e6769746875622e636f6d2f6173736574732f313637363837312f36383130382f62626330636662302d356632392d313165322d393734662d3333393763363464633835382e676966) [animations](https://camo.githubusercontent.com/f4810e00e1c5f5f8addbe3e9f49064fd5d102699/68747470733a2f2f662e636c6f75642e6769746875622e636f6d2f6173736574732f313637363837312f36383130312f38346339323036362d356632392d313165322d383134662d3964336430323431336266642e676966) for how `cargo` and `queue` work.
+
+While [queue](#queue) passes only one task to one of a group of workers
+at a time, cargo passes an array of tasks to a single worker, repeating
+when the worker is finished.
+
+__Arguments__
+
+* `worker(tasks, callback)` - An asynchronous function for processing an array of
+  queued tasks, which must call its `callback(err)` argument when finished, with
+  an optional `err` argument.
+* `payload` - An optional `integer` for determining how many tasks should be
+  processed per round; if omitted, the default is unlimited.
+
+__Cargo objects__
+
+The `cargo` object returned by this function has the following properties and
+methods:
+
+* `length()` - A function returning the number of items waiting to be processed.
+* `payload` - An `integer` for determining how many tasks should be
+  process per round. This property can be changed after a `cargo` is created to
+  alter the payload on-the-fly.
+* `push(task, [callback])` - Adds `task` to the `queue`. The callback is called
+  once the `worker` has finished processing the task. Instead of a single task, an array of `tasks`
+  can be submitted. The respective callback is used for every task in the list.
+* `saturated` - A callback that is called when the `queue.length()` hits the concurrency and further tasks will be queued.
+* `empty` - A callback that is called when the last item from the `queue` is given to a `worker`.
+* `drain` - A callback that is called when the last item from the `queue` has returned from the `worker`.
+* `idle()`, `pause()`, `resume()`, `kill()` - cargo inherits all of the same methods and event calbacks as [`queue`](#queue)
+
+__Example__
+
+```js
+// create a cargo object with payload 2
+
+var cargo = async.cargo(function (tasks, callback) {
+    for(var i=0; i<tasks.length; i++){
+      console.log('hello ' + tasks[i].name);
+    }
+    callback();
+}, 2);
+
+
+// add some items
+
+cargo.push({name: 'foo'}, function (err) {
+    console.log('finished processing foo');
+});
+cargo.push({name: 'bar'}, function (err) {
+    console.log('finished processing bar');
+});
+cargo.push({name: 'baz'}, function (err) {
+    console.log('finished processing baz');
+});
+```
+
+---------------------------------------
+
+<a name="auto" />
+### auto(tasks, [concurrency], [callback])
+
+Determines the best order for running the functions in `tasks`, based on their requirements. Each function can optionally depend on other functions being completed first, and each function is run as soon as its requirements are satisfied.
+
+If any of the functions pass an error to their callback, the `auto` sequence will stop. Further tasks will not execute (so any other functions depending on it will not run), and the main `callback` is immediately called with the error.  Functions also receive an object containing the results of functions which have completed so far.
+
+Note, all functions are called with a `results` object as a second argument,
+so it is unsafe to pass functions in the `tasks` object which cannot handle the
+extra argument.
+
+For example, this snippet of code:
+
+```js
+async.auto({
+  readData: async.apply(fs.readFile, 'data.txt', 'utf-8')
+}, callback);
+```
+
+will have the effect of calling `readFile` with the results object as the last
+argument, which will fail:
+
+```js
+fs.readFile('data.txt', 'utf-8', cb, {});
+```
+
+Instead, wrap the call to `readFile` in a function which does not forward the
+`results` object:
+
+```js
+async.auto({
+  readData: function(cb, results){
+    fs.readFile('data.txt', 'utf-8', cb);
+  }
+}, callback);
+```
+
+__Arguments__
+
+* `tasks` - An object. Each of its properties is either a function or an array of
+  requirements, with the function itself the last item in the array. The object's key
+  of a property serves as the name of the task defined by that property,
+  i.e. can be used when specifying requirements for other tasks.
+  The function receives two arguments: (1) a `callback(err, result)` which must be
+  called when finished, passing an `error` (which can be `null`) and the result of
+  the function's execution, and (2) a `results` object, containing the results of
+  the previously executed functions.
+* `concurrency` - An optional `integer` for determining the maximum number of tasks that can be run in parallel. By default, as many as possible.
+* `callback(err, results)` - An optional callback which is called when all the
+  tasks have been completed. It receives the `err` argument if any `tasks`
+  pass an error to their callback. Results are always returned; however, if
+  an error occurs, no further `tasks` will be performed, and the results
+  object will only contain partial results.
+
+
+__Example__
+
+```js
+async.auto({
+    get_data: function(callback){
+        console.log('in get_data');
+        // async code to get some data
+        callback(null, 'data', 'converted to array');
+    },
+    make_folder: function(callback){
+        console.log('in make_folder');
+        // async code to create a directory to store a file in
+        // this is run at the same time as getting the data
+        callback(null, 'folder');
+    },
+    write_file: ['get_data', 'make_folder', function(callback, results){
+        console.log('in write_file', JSON.stringify(results));
+        // once there is some data and the directory exists,
+        // write the data to a file in the directory
+        callback(null, 'filename');
+    }],
+    email_link: ['write_file', function(callback, results){
+        console.log('in email_link', JSON.stringify(results));
+        // once the file is written let's email a link to it...
+        // results.write_file contains the filename returned by write_file.
+        callback(null, {'file':results.write_file, 'email':'user@example.com'});
+    }]
+}, function(err, results) {
+    console.log('err = ', err);
+    console.log('results = ', results);
+});
+```
+
+This is a fairly trivial example, but to do this using the basic parallel and
+series functions would look like this:
+
+```js
+async.parallel([
+    function(callback){
+        console.log('in get_data');
+        // async code to get some data
+        callback(null, 'data', 'converted to array');
+    },
+    function(callback){
+        console.log('in make_folder');
+        // async code to create a directory to store a file in
+        // this is run at the same time as getting the data
+        callback(null, 'folder');
+    }
+],
+function(err, results){
+    async.series([
+        function(callback){
+            console.log('in write_file', JSON.stringify(results));
+            // once there is some data and the directory exists,
+            // write the data to a file in the directory
+            results.push('filename');
+            callback(null);
+        },
+        function(callback){
+            console.log('in email_link', JSON.stringify(results));
+            // once the file is written let's email a link to it...
+            callback(null, {'file':results.pop(), 'email':'user@example.com'});
+        }
+    ]);
+});
+```
+
+For a complicated series of `async` tasks, using the [`auto`](#auto) function makes adding
+new tasks much easier (and the code more readable).
+
+
+---------------------------------------
+
+<a name="retry" />
+### retry([opts = {times: 5, interval: 0}| 5], task, [callback])
+
+Attempts to get a successful response from `task` no more than `times` times before
+returning an error. If the task is successful, the `callback` will be passed the result
+of the successful task. If all attempts fail, the callback will be passed the error and
+result (if any) of the final attempt.
+
+__Arguments__
+
+* `opts` - Can be either an object with `times` and `interval` or a number.
+  * `times` - The number of attempts to make before giving up.  The default is `5`.
+  * `interval` - The time to wait between retries, in milliseconds.  The default is `0`.
+  * If `opts` is a number, the number specifies the number of times to retry, with the default interval of `0`. 
+* `task(callback, results)` - A function which receives two arguments: (1) a `callback(err, result)`
+  which must be called when finished, passing `err` (which can be `null`) and the `result` of
+  the function's execution, and (2) a `results` object, containing the results of
+  the previously executed functions (if nested inside another control flow).
+* `callback(err, results)` - An optional callback which is called when the
+  task has succeeded, or after the final failed attempt. It receives the `err` and `result` arguments of the last attempt at completing the `task`.
+
+The [`retry`](#retry) function can be used as a stand-alone control flow by passing a callback, as shown below:
+
+```js
+// try calling apiMethod 3 times
+async.retry(3, apiMethod, function(err, result) {
+    // do something with the result
+});
+```
+
+```js
+// try calling apiMethod 3 times, waiting 200 ms between each retry 
+async.retry({times: 3, interval: 200}, apiMethod, function(err, result) {
+    // do something with the result
+});
+```
+
+```js
+// try calling apiMethod the default 5 times no delay between each retry 
+async.retry(apiMethod, function(err, result) {
+    // do something with the result
+});
+```
+
+It can also be embedded within other control flow functions to retry individual methods
+that are not as reliable, like this:
+
+```js
+async.auto({
+    users: api.getUsers.bind(api),
+    payments: async.retry(3, api.getPayments.bind(api))
+}, function(err, results) {
+  // do something with the results
+});
+```
+
+
+---------------------------------------
+
+<a name="iterator" />
+### iterator(tasks)
+
+Creates an iterator function which calls the next function in the `tasks` array,
+returning a continuation to call the next one after that. It's also possible to
+“peek” at the next iterator with `iterator.next()`.
+
+This function is used internally by the `async` module, but can be useful when
+you want to manually control the flow of functions in series.
+
+__Arguments__
+
+* `tasks` - An array of functions to run.
+
+__Example__
+
+```js
+var iterator = async.iterator([
+    function(){ sys.p('one'); },
+    function(){ sys.p('two'); },
+    function(){ sys.p('three'); }
+]);
+
+node> var iterator2 = iterator();
+'one'
+node> var iterator3 = iterator2();
+'two'
+node> iterator3();
+'three'
+node> var nextfn = iterator2.next();
+node> nextfn();
+'three'
+```
+
+---------------------------------------
+
+<a name="apply" />
+### apply(function, arguments..)
+
+Creates a continuation function with some arguments already applied.
+
+Useful as a shorthand when combined with other control flow functions. Any arguments
+passed to the returned function are added to the arguments originally passed
+to apply.
+
+__Arguments__
+
+* `function` - The function you want to eventually apply all arguments to.
+* `arguments...` - Any number of arguments to automatically apply when the
+  continuation is called.
+
+__Example__
+
+```js
+// using apply
+
+async.parallel([
+    async.apply(fs.writeFile, 'testfile1', 'test1'),
+    async.apply(fs.writeFile, 'testfile2', 'test2'),
+]);
+
+
+// the same process without using apply
+
+async.parallel([
+    function(callback){
+        fs.writeFile('testfile1', 'test1', callback);
+    },
+    function(callback){
+        fs.writeFile('testfile2', 'test2', callback);
+    }
+]);
+```
+
+It's possible to pass any number of additional arguments when calling the
+continuation:
+
+```js
+node> var fn = async.apply(sys.puts, 'one');
+node> fn('two', 'three');
+one
+two
+three
+```
+
+---------------------------------------
+
+<a name="nextTick" />
+### nextTick(callback), setImmediate(callback)
+
+Calls `callback` on a later loop around the event loop. In Node.js this just
+calls `process.nextTick`; in the browser it falls back to `setImmediate(callback)`
+if available, otherwise `setTimeout(callback, 0)`, which means other higher priority
+events may precede the execution of `callback`.
+
+This is used internally for browser-compatibility purposes.
+
+__Arguments__
+
+* `callback` - The function to call on a later loop around the event loop.
+
+__Example__
+
+```js
+var call_order = [];
+async.nextTick(function(){
+    call_order.push('two');
+    // call_order now equals ['one','two']
+});
+call_order.push('one')
+```
+
+<a name="times" />
+### times(n, iterator, [callback])
+
+Calls the `iterator` function `n` times, and accumulates results in the same manner
+you would use with [`map`](#map).
+
+__Arguments__
+
+* `n` - The number of times to run the function.
+* `iterator` - The function to call `n` times.
+* `callback` - see [`map`](#map)
+
+__Example__
+
+```js
+// Pretend this is some complicated async factory
+var createUser = function(id, callback) {
+  callback(null, {
+    id: 'user' + id
+  })
+}
+// generate 5 users
+async.times(5, function(n, next){
+    createUser(n, function(err, user) {
+      next(err, user)
+    })
+}, function(err, users) {
+  // we should now have 5 users
+});

+
+<a name="memoize" />
+### memoize(fn, [hasher])
+
+Caches the results of an `async` function. When creating a hash to store function
+results against, the callback is omitted from the hash and an optional hash
+function can be used.
+
+If no hash function is specified, the first argument is used as a hash key, which may work reasonably if it is a string or a data type that converts to a distinct string. Note that objects and arrays will not behave reasonably. Neither will cases where the other arguments are significant. In such cases, specify your own hash function.
+
+The cache of results is exposed as the `memo` property of the function returned
+by `memoize`.
+
+__Arguments__
+
+* `fn` - The function to proxy and cache results from.
+* `hasher` - An optional function for generating a custom hash for storing
+  results. It has all the arguments applied to it apart from the callback, and
+  must be synchronous.
+
+__Example__
+
+```js
+var slow_fn = function (name, callback) {
+    // do something
+    callback(null, result);
+};
+var fn = async.memoize(slow_fn);
+
+// fn can now be used as if it were slow_fn
+fn('some name', function () {
+    // callback
+});
+```
+
+<a name="unmemoize" />
+### unmemoize(fn)
+
+Undoes a [`memoize`](#memoize)d function, reverting it to the original, unmemoized
+form. Handy for testing.
+
+__Arguments__
+
+* `fn` - the memoized function
+
+---------------------------------------
+
+<a name="ensureAsync" />
+### ensureAsync(fn)
+
+Wrap an async function and ensure it calls its callback on a later tick of the event loop.  If the function already calls its callback on a next tick, no extra deferral is added. This is useful for preventing stack overflows (`RangeError: Maximum call stack size exceeded`) and generally keeping [Zalgo](http://blog.izs.me/post/59142742143/designing-apis-for-asynchrony) contained.
+
+__Arguments__
+
+* `fn` - an async function, one that expects a node-style callback as its last argument
+
+Returns a wrapped function with the exact same call signature as the function passed in.
+
+__Example__
+
+```js
+function sometimesAsync(arg, callback) {
+  if (cache[arg]) {
+    return callback(null, cache[arg]); // this would be synchronous!!
+  } else {
+    doSomeIO(arg, callback); // this IO would be asynchronous
+  }
+}
+
+// this has a risk of stack overflows if many results are cached in a row
+async.mapSeries(args, sometimesAsync, done);
+
+// this will defer sometimesAsync's callback if necessary,
+// preventing stack overflows
+async.mapSeries(args, async.ensureAsync(sometimesAsync), done);
+
+```
+
+---------------------------------------
+
+<a name="constant">
+### constant(values...)
+
+Returns a function that when called, calls-back with the values provided.  Useful as the first function in a `waterfall`, or for plugging values in to `auto`.
+
+__Example__
+
+```js
+async.waterfall([
+  async.constant(42),
+  function (value, next) {
+    // value === 42
+  },
+  //...
+], callback);
+
+async.waterfall([
+  async.constant(filename, "utf8"),
+  fs.readFile,
+  function (fileData, next) {
+    //...
+  }
+  //...
+], callback);
+
+async.auto({
+  hostname: async.constant("https://server.net/"),
+  port: findFreePort,
+  launchServer: ["hostname", "port", function (cb, options) {
+    startServer(options, cb);
+  }],
+  //...
+}, callback);
+
+```
+
+---------------------------------------
+
+<a name="asyncify">
+<a name="wrapSync">
+### asyncify(func)
+
+__Alias:__ `wrapSync`
+
+Take a sync function and make it async, passing its return value to a callback. This is useful for plugging sync functions into a waterfall, series, or other async functions. Any arguments passed to the generated function will be passed to the wrapped function (except for the final callback argument). Errors thrown will be passed to the callback.
+
+__Example__
+
+```js
+async.waterfall([
+  async.apply(fs.readFile, filename, "utf8"),
+  async.asyncify(JSON.parse),
+  function (data, next) {
+    // data is the result of parsing the text.
+    // If there was a parsing error, it would have been caught.
+  }
+], callback)
+```
+
+If the function passed to `asyncify` returns a Promise, that promises's resolved/rejected state will be used to call the callback, rather than simply the synchronous return value.  Example:
+
+```js
+async.waterfall([
+  async.apply(fs.readFile, filename, "utf8"),
+  async.asyncify(function (contents) {
+    return db.model.create(contents);
+  }),
+  function (model, next) {
+    // `model` is the instantiated model object. 
+    // If there was an error, this function would be skipped.
+  }
+], callback)
+```
+
+This also means you can asyncify ES2016 `async` functions.
+
+```js
+var q = async.queue(async.asyncify(async function (file) {
+  var intermediateStep = await processFile(file);
+  return await somePromise(intermediateStep)
+}));
+
+q.push(files);

+<a name="log" />
+### log(function, arguments)
+
+Logs the result of an `async` function to the `console`. Only works in Node.js or
+in browsers that support `console.log` and `console.error` (such as FF and Chrome).
+If multiple arguments are returned from the async function, `console.log` is
+called on each argument in order.
+
+__Arguments__
+
+* `function` - The function you want to eventually apply all arguments to.

+# backo
+
+  Simple exponential backoff because the others seem to have weird abstractions.
+
+## Installation
+
+```
+$ npm install backo
+```
+
+## Options
+
+ - `min` initial timeout in milliseconds [100]
+ - `max` max timeout [10000]
+ - `jitter` [0]
+ - `factor` [2]
+
+## Example
+
+```js
+var Backoff = require('backo');
+var backoff = new Backoff({ min: 100, max: 20000 });
+
+setTimeout(function(){
+  something.reconnect();
+}, backoff.duration());
+
+// later when something works
+backoff.reset()

+```
+
+The matches are:
+
+```bash
+$ node example.js
+{ start: 3, end: 14, pre: 'pre', body: 'in{nested}', post: 'post' }
+{ start: 3,
+  end: 9,
+  pre: 'pre',
+  body: 'first',
+  post: 'between{second}post' }
+{ start: 3, end: 17, pre: 'pre', body: 'in{nest}', post: 'post' }
+```
+
+## API
+
+### var m = balanced(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+object with those keys:
+
+* **start** the index of the first match of `a`
+* **end** the index of the matching `b`
+* **pre** the preamble, `a` and `b` not included
+* **body** the match, `a` and `b` not included
+* **post** the postscript, `a` and `b` not included
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `['{', 'a', '']` and `{a}}` will match `['', 'a', '}']`.
+
+### var r = balanced.range(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+array with indexes: `[ <a index>, <b index> ]`.
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `[ 1, 3 ]` and `{a}}` will match `[0, 2]`.

+base64id
+========
+
+Node.js module that generates a base64 id.
+
+Uses crypto.randomBytes when available, falls back to unsafe methods for node.js <= 0.4.
+
+To increase performance, random bytes are buffered to minimize the number of synchronous calls to crypto.randomBytes.
+
+## Installation
+
+   $ npm install base64id
+
+## Usage
+
+   var base64id = require('base64id');

+# better-assert
+
+  Better c-style assertions using [callsite](https://github.com/visionmedia/callsite) for
+  self-documenting failure messages.
+
+## Installation
+
+    $ npm install better-assert
+
+## Example
+
+ By default assertions are enabled, however the __NO_ASSERT__ environment variable 
+ will deactivate them when truthy.
+
+```js
+var assert = require('better-assert');
+
+test();
+
+function test() {
+  var user = { name: 'tobi' };
+  assert('tobi' == user.name);
+  assert('number' == typeof user.age);
+}
+
+AssertionError: 'number' == typeof user.age
+    at test (/Users/tj/projects/better-assert/example.js:9:3)
+    at Object.<anonymous> (/Users/tj/projects/better-assert/example.js:4:1)

+
+[Brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html), 
+as known from sh/bash, in JavaScript.
+
+[![build status](https://secure.travis-ci.org/juliangruber/brace-expansion.svg)](http://travis-ci.org/juliangruber/brace-expansion)
+[![downloads](https://img.shields.io/npm/dm/brace-expansion.svg)](https://www.npmjs.org/package/brace-expansion)
+[![Greenkeeper badge](https://badges.greenkeeper.io/juliangruber/brace-expansion.svg)](https://greenkeeper.io/)
+
+[![testling badge](https://ci.testling.com/juliangruber/brace-expansion.png)](https://ci.testling.com/juliangruber/brace-expansion)
+
+## Example
+
+```js
+var expand = require('brace-expansion');
+
+expand('file-{a,b,c}.jpg')
+// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
+
+expand('-v{,,}')
+// => ['-v', '-v', '-v']
+
+expand('file{0..2}.jpg')
+// => ['file0.jpg', 'file1.jpg', 'file2.jpg']
+
+expand('file-{a..c}.jpg')
+// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
+
+expand('file{2..0}.jpg')
+// => ['file2.jpg', 'file1.jpg', 'file0.jpg']
+
+expand('file{0..4..2}.jpg')
+// => ['file0.jpg', 'file2.jpg', 'file4.jpg']
+
+expand('file-{a..e..2}.jpg')
+// => ['file-a.jpg', 'file-c.jpg', 'file-e.jpg']
+
+expand('file{00..10..5}.jpg')
+// => ['file00.jpg', 'file05.jpg', 'file10.jpg']
+
+expand('{{A..C},{a..c}}')
+// => ['A', 'B', 'C', 'a', 'b', 'c']
+
+expand('ppp{,config,oe{,conf}}')
+// => ['ppp', 'pppconfig', 'pppoe', 'pppoeconf']
+```
+
+## API
+
+```js
+var expand = require('brace-expansion');
+```
+
+### var expanded = expand(str)
+
+Return an array of all possible and valid expansions of `str`. If none are
+found, `[str]` is returned.
+
+Valid expansions are:
+
+```js
+/^(.*,)+(.+)?$/
+// {a,b,...}
+```
+
+A comma separated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+A numeric sequence from `x` to `y` inclusive, with optional increment.
+If `x` or `y` start with a leading `0`, all the numbers will be padded
+to have equal length. Negative numbers and backwards iteration work too.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+An alphabetic sequence from `x` to `y` inclusive, with optional increment.
+`x` and `y` must be exactly one character, and if given, `incr` must be a
+number.
+
+For compatibility reasons, the string `${` is not eligible for brace expansion.
+
+## Installation
+

+# bunyan Changelog
+
+## 1.6.1
+
+- Copying the options object given from the caller as it may be immutable and we like to change things, set defaults, etc.
+
+## 1.6.0
+
+- Support writing logs that aren't in bunyan's normal JSON format. Or JSON at all.
+- Officially moved tests to node 6
+
+## 1.5.4
+
+- Checked with node v6 and updated support notes on the README.
+
+## 1.5.3
+
+- Fixed issue with handling template filenames containing dots: #4
+
+- Can handle this.%Y.log as well as this.%N-%Y.log, which both failed before, when using gzip.
+
+## 1.5.2
+
+- Expanded node version compatibility and making a statement about which versions of node we offically support- `0.12.9`, `0.12.latest`, `4.latest`, `5.latest`.
+
+- Full passing test suites running against each version using `nvm`.
+
+- Stress test in place, needs tuning.
+
+## 1.5.1
+
+- Fixed an issue with gzipped files not being deleted when using datestamps
+- Fixed an issue with gzipped files not being rotated correctly when continuing an existing log file
+
+## 1.5.0 Templates Release
+
+We now have the ability to specify templates in the log's filename. For full details see the templating section, but briefly: we can template where you put the number when rotating files (this allows you to preserve the extension so that the files open in the correct viewer), or give your log filename a timestamp in your preferred format.
+All previous features are maintained and you should be able to use your existing configuration without change.
+
+Integration testing is still rudimentary in terms of technology, but the coverage has been massively improved, checking that no logs have been re-ordered or lost.
+
+## 1.4.0
+- New feature to allow the user to specify the order the fields of the log records are written to the log file, this can make manual browsing of the files easier if you put the timestamp and other relevant information first.
+- Some clean ups and refactorings to try to remove some flags.
+
+## 1.3.1
+
+- Fix bug: If we started rotating files in the middle of a write batch, the remaining logs in the batch would be reversed.
+- Start rotating if a log record would breach a threshold rather than rotate after threshold reached.
+
+## 1.3.0
+
+- It appears to be a very common problem that multiple rotating file streams are created against the same file. This version should resolve this issue when done within the same process by caching and returning the first rotating stream created.
+
+## 1.2.1
+
+- Catching write errors and emitting them
+- Ensuring a stream is closed before finishing a join (internal testing method)
+- Handling events in the underlying stream
+
+## 1.2.0
+
+- Support non-raw streams. For some reason, raw streams are MUCH faster in high load scenarios (at least when this is the only stream).
+- Better guarantees over file rollover - we will write exactly one log record that goes over the size threshold before we rotate
+  The previous performance release meant that we couldn't rotate until the write had completed to the disk - in the meantime several other
+  logs could have been written. This made everything unpredictable.
+- Making better use of the cargo datatype to write multiple log records in a single event loop tick.
+- Using setImmediate rather than process.nextTick in the write loop to allow io and other operations time to happen rather than hog the event loop.
+
+## 1.1.1
+
+- Being far more aggressive when writing logs in order to improve log writing speed
+- Basic performance test that writes 1million logs
+
+## 1.1.0
+
+- Adding ability to rotate existing log files when we open them up with the "rotateExisting" feature.
+
+## 1.0.6
+
+- Fixing special values (eg, 'hourly') for period rollover. These were broken in v1.0.5
+
+## 1.0.5
+
+- Restructured project
+- Moved to a properly named git repository with only this project's history in it
+- Added basic tests to excercise everything and make sure nothing is broken
+
+## 1.0.4
+
+- Correcting github location
+
+## 1.0.3
+
+- Docs changes
+
+## 1.0.2
+
+- Getting the right filepath to import from package.json
+
+## 1.0.1
+
+- Minor docs update
+
+## 1.0.0 (First release)
+
+- First release

+# Contributing to node-bunyan
+
+Thanks for using node-bunyan and for considering contributing to it! Or perhaps
+you are just here to get a sniff for what is going on with node-bunyan
+development.
+
+
+## How you can help
+
+If you want to help me here, great! Thank you! Some ideas:
+
+- Do you have experience with and/or recommendations for a good automated
+  testing service? Ideally I'd like support for Mac, Linux, SmartOS, and maybe
+  Windows. Also, support for node.js versions 0.10 up to whatever the current
+  latest is. Are those too tall an order? What's more, Bunyan is meant to work
+  (at least partially) in the browser. Is there a good service for that?
+  Please discuss on [issue #342](https://github.com/trentm/node-bunyan/issues/342).
+
+- Fielding issues labelled with "[Type-Question][Type-Question]", if you are familiar
+  with Bunyan and know how to answer them, would be great.
+
+- If you want to dive into code, but aren't *that* familiar with node-bunyan,
+  then [issues labelled with Experience-Easy][Experience-Easy] are a good
+  place to start.
+
+- [Once I've made a once over
+  triaging](https://github.com/trentm/node-bunyan/issues/335) and consolodating
+  issues and PRs, volunteering for issues in a particular
+  [component](#component) with which you have familiarity would be great.
+
+[Type-Question]: https://github.com/trentm/node-bunyan/issues?q=is%3Aopen+is%3Aissue+label%3AType-Question
+
+
+## Trent's Biased Rules for Code
+
+In the hope that it makes it easier to get PRs into Bunyan, here is my biased
+list of what I typically want. Submitting a PR without all of these is
+*totally fine*! The only side-effect is that it may take longer for me to
+provide feedback on it and merge it. I'll politely request missing pieces.
+
+
+- Please follow existing code style. Contributed code must pass `make check`.
+  (Note: I intended to [change to eslint
+  soon](https://github.com/trentm/node-bunyan/issues/341), so currently `make
+  check` might be a moving target.)
+
+- Any user visible change in behaviour should almost certainly include an
+  update to the docs. Currently the "docs" is the README.md.
+
+- Adding a test case for code changes is **stronly recommended**, else I
+  can't easily promise to not break your fix/feature later. If you don't
+  grok the test suite, please ask. We can use it to form the basis for a
+  "test/README.md".
+
+- Typically a code change should have an associated issue or PR. This allows
+  addition of follow-up issues, discussion, test data, etc. to be associated
+  with the commit. Just using GitHub pull requests makes this easy.
+
+- All but the most trivial code changes should have an addition to the
+  [changelog](./CHANGES.md). The audience for the changelog is *Bunyan users*.
+  However, because rebasing longer-lived PRs against master is a pain
+  with a change to CHANGES.md, please **do not include a CHANGES.md change
+  in your PR. Instead suggest a CHANGES.md addition in a comment on the
+  PR.**
+
+- Good commit messages, please:
+    - The first line should be a succinct summary of the issue or fix. A
+      good candidate is to just cut 'n paste the issue title, if there is one.
+    - If the commit is for a particular issue/PR (see previous rule), please
+      list the issue number in the commit message. E.g. "Fixes #123" or "Related
+      to #234".
+    - The audience for commit messages is *Bunyan developers*.
+
+
+## Pull Request Lifecycle
+
+(Language adapted from
+[terraform](https://github.com/hashicorp/terraform/blob/master/CONTRIBUTING.md).)
+
+- You are welcome to submit your pull request for commentary or review before it
+  is fully completed. Please prefix the title of your pull request with "[WIP]"
+  to indicate this. It's also a good idea to include specific questions or items
+  you'd like feedback on.
+
+- Once you believe your pull request is ready to be merged, you can remove any
+  "[WIP]" prefix from the title and a core team member will review. See
+  Trent's Biased Rules above to help ensure that your contribution will be
+  merged quickly.
+
+- Trent or, if things go well, a node-bunyan maintainer will look over your
+  contribution and either provide comments letting you know if there is anything
+  left to do. Please be patient. Unfortunately, I'm not able to carve out
+  a *lot* of time for Bunyan development and maintenance.
+
+- Once all outstanding comments and checklist items have been addressed, your
+  contribution will be merged. Merged PRs will be included in the next
+  node-bunyan release.
+
+- In some cases, we might decide that a PR should be closed. We'll make sure to
+  provide clear reasoning when this happens.
+
+
+## Issue labels
+
+The point of issue labeling for node-bunyan is to help answer "what should be
+worked on now? what can be left for later?" I don't want issue labelling to
+become a burden for anyone, so (a) don't feel obliged to add them yourself and
+(b) I'm happy to reevaluate their usage.
+
+Bunyan shall have categories of [issue
+labels](https://github.com/trentm/node-bunyan/labels) named "$category-$value".
+An issue should have max *one* label from each set. Users of Google Code's
+dearly departed issue tracker may remember this kind of thing. This is a
+poorman's version of structured issue tracker metadata.
+
+I'm inclined to *not* do priorities right now. *Possibly* we'll use GitHub
+milestones to basically set targets for upcoming releases. But otherwise my
+sense is that for smaller OSS projects, assigning prios will get in the way.
+If people would think it helpful, I'd consider "Difficulty-" or "Experience-"
+categories (a la Rust's "E-" labels) to mark easier and intermediate tasks
+that someone interested but maybe not very familiar with Bunyan might want
+to tackle.
+
+For now, here are the various labels and their purpose:
+
+### Meta
+
+- needstriage: Temporary label to help me do a single triage pass through all
+  current open issues and PRs.
+  See [#335](https://github.com/trentm/node-bunyan/issues/335)
+  where I'm working through this.
+
+### Type
+
+Color: green
+
+- Type-Unknown: If it is still unclear or undecided if an issue is an intended
+  feature (perhaps arguing for better docs or examples to avoid confusion) or a
+  bug, I will use this category.
+- Type-Question: Asking a question on Bunyan usage, about the project, etc.
+- Type-Bug: A bug in Bunyan's behaviour.
+- Type-Feature: A new feature or other improvement.
+- Type-Doc: Issues with Bunyan's documentation.
+- Type-Task: A project task to be done.
+
+TODO: consider Type-Unknown for the "unclear if bug or feature" tickets.
+
+### Component
+
+Color: blue
+
+- Component-Project: Project meta stuff like testing, linting, build, install,
+  etc.
+- Component-CLI: The `bunyan` command-line tool.
+- Component-Lib: catch-all for other library stuff
+    - Component-LibRotation: The bunyan library's log rotation support.
+    - Component-LibBrowser: Bunyan's handling/support for running in the browser.
+    - Component-LibFlush: A separate component for collecting the tickets related
+      to closing/flushing bunyan streams on process shutdown.
+
+The point of components is to find like issues to help with reference, search
+and resolving them. If no component fits an issue/PR, then don't add a label.
+
+### Resolution
+
+Color: red
+
+- Resolution-WontFix
+- Resolution-Duplicate
+- Resolution-Fixed: Also used to indicate "doc written", "question answered",
+  "feature implemented".
+- Resolution-CannotRepro: After some reasonable attempt by maintainers to
+  reproduce a bug report, I want it to be non-controversial to close it
+  and mark it with this. If given more info by someone able to repro, we
+  can happy re-open issues.
+
+### Experience
+
+Color: yellow
+
+- Experience-Easy: Relatively little experience with node-bunyan should be
+  required to complete this issue.
+- Experience-NeedsTest: Typically added to an issue or PR that needs a test
+  case. Someone familiar enough with node-bunyan's test suite could tackle this.
+- Experience-Hard: At a guess, this is a thorny issue that requires known
+  node-bunyan well, knowing node.js well, requires design review or all of
+  these.
+
+One of the "Experience-\*" labels can optionally be put on an issue or PR to
+indicate what kind of experience a contributor would need with node-bunyan
+(and/or node.js) to complete it. For example, if you're looking for somewhere to
+start, check out the [Experience-Easy][Experience-Easy] tag. This category idea
+is borrowed from [rust's E-\* labels][rust-issue-triage].
+
+[Experience-Easy]: https://github.com/trentm/node-bunyan/issues?q=is%3Aopen+is%3Aissue+label%3AExperience-Easy
+[rust-issue-triage]: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#issue-triage

+Bunyan Rotating File Stream is a stream component for the logging system "node bunyan" that provides rich and flexible control over your log files.
+
+[![Join the chat at https://gitter.im/Rcomian/bunyan-rotating-file-stream](https://badges.gitter.im/Rcomian/bunyan-rotating-file-stream.svg)](https://gitter.im/Rcomian/bunyan-rotating-file-stream?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
+
+```js
+    var log = bunyan.createLogger({
+        name: 'foo',
+        streams: [{
+            stream: new RotatingFileStream({
+                path: '/var/log/foo.log',
+                period: '1d',          // daily rotation
+                totalFiles: 10,        // keep up to 10 back copies
+                rotateExisting: true,  // Give ourselves a clean file when we start up, based on period
+                threshold: '10m',      // Rotate log files larger than 10 megabytes
+                totalSize: '20m',      // Don't keep more than 20mb of archived log files
+                gzip: true             // Compress the archive log files to save space
+            })
+        }]
+    });
+```
+
+# Recent changes
+
+## 1.6.3 Type definition file for Typescript
+
+Generously provided by: scippio
+
+## 1.6.2 Fixed support for the "rotateExisting" flag
+
+Tests have been added to ensure that this feature keeps working in the future.
+Note that this feature may not work as expected with linux on EXT4.
+
+## 1.6 Support for non-JSON logs
+
+Minor release but now that logs which are written in a non-json format are supported.
+
+## 1.5 Templates Release
+
+We now have the ability to specify templates in the log's filename. For full details see the templating section, but briefly: we can template where you put the number when rotating files (this allows you to preserve the extension so that the files open in the correct viewer), or give your log filename a timestamp in your preferred format.
+All previous features are maintained and you should be able to use your existing configuration without change.
+
+Integration testing is still rudimentary in terms of technology, but the coverage has been massively improved, checking that no logs have been re-ordered or lost.
+
+
+# Compatibility
+
+Implemented tests and strategies to support specific node versions:
+
+* 0.12.*latest*
+* 4.*latest*
+* 6.*latest*
+* 7.*latest*
+
+*0.10 and earlier*
+
+Not supported as it is missing a lot of useful path processing features. Whilst we could patch this with inline code and npm packages, I think it's a shame to have these hanging around when the functionality will be built into all future versions of node.
+
+*0.12*
+
+Is supported, but it's performance cannot keep up with the latest versions of node. I've had to reduce the stress involved when running tests to allow old `0.12` to keep up.
+
+*5*
+
+Is supported, but won't be stress tested as those resources are being used for the LTS releases 0.12, 4 & 6.
+
+
+# Current Status
+
+The basics of the features are there, you should be able to use the
+rotating file logging to limit disk space usage while maximising
+the amount of logs kept.
+
+There are a few extra features to add to the system, but in general it needs stabilisation, code cleanup and bug fixing.
+
+We can now regularly run feature tests against all supported versions of node.
+
+
+# Planned Future Features
+
+* Prevent multiple processes logging to the same file
+* Allow multiple processes to safely log to the same file
+* Allow you to say where to put the number in date formatted file names
+
+# Installation
+
+```sh
+npm install bunyan-rotating-file-stream
+```
+
+# Main Features
+
+- Name log files with templates
+- Rotate to a new log file periodically (can also rotate on startup to clean old log files)
+- Rotate to a new log file once the main log file goes over a certain size
+- Keep a maximum number of archival log files
+- Delete older log files once the archive reaches a certain size
+- GZip archived log files
+- Supports being a raw stream or a normal stream
+
+
+## How to use
+
+**WARNING on node 0.8 usage:** Users should use at
+least node 0.10 (node 0.8 does not support the `unref()` method on
+`setTimeout(...)`). The symptom is that process
+termination will hang for up to a full rotation period if period rotation is used.
+You can manually keep hold of the logger and call "shutdown" to prevent this.
+
+**WARNING on [cluster](http://nodejs.org/docs/latest/api/all.html#all_cluster)
+usage:** Using `bunyan-rotating-file-stream` with node.js's "cluster" module
+can result in unexpected file rotation. You must not have multiple processes
+in the cluster logging to the same file path. In other words, you must have
+a separate log file path for the master and each worker in the cluster.
+Alternatively, consider using a system file rotation facility such as
+`logrotate` on Linux or `logadm` on SmartOS/Illumos. See
+[this comment on issue #117](https://github.com/trentm/node-bunyan/issues/117#issuecomment-44804938)
+for details.
+
+Add this stream directly to the bunyan logger.
+The stream supports being both a raw and normal stream modes. Raw streams can be faster
+under some high-load scenarios but may serialize the json differently to bunyan.
+
+```js
+    var bunyan = require('bunyan');
+    var RotatingFileStream = require('bunyan-rotating-file-stream');
+
+    var log = bunyan.createLogger({
+        name: 'foo',
+        streams: [{
+            type: 'raw',
+            stream: new RotatingFileStream({
+                path: '/var/log/foo.log',
+                period: '1d',          // daily rotation
+                totalFiles: 10,        // keep 10 back copies
+                rotateExisting: true,  // Give ourselves a clean file when we start up, based on period
+                threshold: '10m',      // Rotate log files larger than 10 megabytes
+                totalSize: '20m',      // Don't keep more than 20mb of archived log files
+                gzip: true             // Compress the archive log files to save space
+            })
+        }]
+    });
+```
+
+This will rotate '/var/log/foo.log' every day (at midnight) to:
+
+```sh
+/var/log/foo.log.1     # yesterday
+/var/log/foo.log.2     # 1 day ago
+/var/log/foo.log.3     # 2 days ago
+```

+This doesn't affect how programs read each log record if they just JSON.parse each line at a time, it's
+purely for visual browsing when you scan through the text file.
+For this to work, the stream must be set to "raw" mode. You can't use this option without that setting.
+This option has a measurable performance impact as it's copying each log entry object, so be aware if you're
+using this in heavily loaded systems.</p>
+
+<p>*note* This feature currently works using an undocumented and un-guaranteed side effect of how serialisation
+works. It may break for a time on new versions of node if the internals of serialisation change how things work.

+
+## rotateExisting and Linux filesystems (EXT4) support
+
+Some filesystems on Linux (in particular EXT4) do not record the file creation date.
+
+Since the rotateExisting requires us to look at this date to see if the file would have been rotated had the
+system been running for all that time, this feature cannot work as required.
+
+You can check if this feature will work on your filesystem by executing `stat [mylogfile]`. If the "Birth" field
+has a value in it, rfs will be able to see the creation time correctly.
+
+Otherwise behaviour of this flag will be based on what birthtime is filled with. If it returns 0, then the file
+will always be rotated. If it returns ctime, it will only be rotated if the rotation period has expired since the
+last write.
+
+# Templating
+
+## Behaviour without templating
+
+By default, if you just give a normal filename for your log, it will be rotated by appending a number to the end of the file.
+
+For example, if you log to a file `webapi.log`, you'll have the following in your log directory:
+
+```
+    webapi.log  // log file having logs written to it.
+```
+
+When the file needs to be rotated, we'll rename the existing file to `webapi.log.1` and create a new empty file `webapi.log`. Giving you:
+
+```
+    webapi.log   // new log file, logs will be written here.
+    webapi.log.1 // old log file, for archival only.
+```
+
+When we rotate again, we rename the `.1` file to `.2`, the log file to `.1` and create another file, giving us:
+
+```
+    webapi.log   // new log file, logs will be written here.
+    webapi.log.1 // archive of the previously active log file.
+    webapi.log.2 // oldest log file containing oldest entries.
+```
+
+As you can see, the extension of the log files is effectively changed to a number, making it lose its association with any tool that you use to open log files and look at them.
+
+## Rotation number templating [%N]
+
+We can tell the system where to insert the rotation number in the filename. To do this, use the `%N` template parameter (uppercase N). This parameter can only appear in the filename, not in the directories or the extension.
+
+If you use the parameter to make `webapi.%N.log`, after the 2 rotations as above, we end up with:
+
+```
+    webapi.log   // the log file receiving new logs.
+    webapi.1.log // archive of the previously active log file.
+    webapi.2.log // oldest log file containing oldest entries.
+```
+
+Notice that the %N has been stripped out of the name for the active log file - we have no number so we have nothing to put there. If the preceding character is `'.', '_' or '-'`, then that will be stripped out too.
+
+This preserves both the numbering system of the archived files and their extension, so we can open them with the correct tool when we click on them.
+
+## Datetime templating [%Y %m %d %H %M %S]
+
+We can also insert the current time into the log file name. This is the time that the log file was created and should contain logs from that time onwards (notice: this is a hint, not a guarantee: there may be some stragglers from the previous file).
+
+When we do this, we no-longer do any renaming when we rotate to a new log file - we simply create a new file with a new timestamp and use that.
+
+The filename is formatted using <https://www.npmjs.com/package/strftime> and so supports any of the format strings they allow.
+The template parameters must be in the main body of the filename and cannot be in the extension (after the last dot in the name) or in the directories leading up to it.
+
+As an example, we can use the a log name for our system like: `webapi.%d-%b-%y.log`. If we then rotated twice, on separate days, we'd end up with the following files:
+
+```
+    webapi.28-Feb-16.log // Oldest file containing the oldest logs
+    webapi.29-Feb-16.log
+    webapi.01-Mar-16.log // Current file receiving logs
+```
+
+### Filename clashes
+
+The file stream makes no requirement that your filename be particularly unique or sort sensibly in any way. If in the previous example, we rotated twice on the same day, we'd differentiate the files by adding a number like this:
+
+```
+    webapi.28-Feb-16.log   // Original file containing the oldest logs
+    webapi.28-Feb-16.1.log
+    webapi.28-Feb-16.2.log // Current file receiving logs
+```
+
+As with rotating number templating, you can specify where this differentiating number goes using %N.
+
+### Deleting old files
+
+When deleting files based on how many archive files we want to keep, or how much space we want to give to log archives, we delete the oldest files based on the modified time of that file.
+
+When we look for files to delete, we look at all the files in the directory that:
+
+* Match up to the first % sign in the filename template
+* Have the same extension (excluding the .gz if you are compressing old files)
+
+Any files matching those criteria are considered part of the logging system and will be deleted based on the normal deletion rules.
+
+# Creating new files on startup
+
+When we startup we look for any existing log files to append to. If we find a viable file, we simply open it and start appending logs to it. This is the behaviour for all files, whether templated or not.
+
+## Rotating old files [{rotateExisting: true}]
+If an old file should have been rotated but your process wasn't running at the time (maybe you choose to have a new file every day, but the process wasn't running at midnight), we will still append to it. Force a rotation on old files using the option: `{rotateExisting: true}`. This will only rotate files that would have been rotated had we stayed running. This option works for templated or non-templated files.
+
+
+**Note 1: Timestamp in filename**: If your log files have a timestamp in the filename, the timestamp will match when the file would have last rotated, not the current time.
+
+**Note 2: Size thresholds**: If a file would be rotated because of a change in threshold size between runs, then that rotation will happen on the first log write as normal regardless of any flags that are set.
+
+## Force new files [{startNewFile: true}]
+Instead of appending logs to an existing file, you can force a new file to be created using the option: `{startNewFile: true}`.
+If the file date stamp clashes with an existing file, the dotted number notation will be used as normal.
+
+
+# Versioning
+
+The scheme I follow is most succinctly described by the bootstrap guys
+[here](https://github.com/twitter/bootstrap#versioning).
+
+tl;dr: All versions are `<major>.<minor>.<patch>` which will be incremented for
+breaking backward compat and major reworks, new features without breaking
+change, and bug fixes, respectively.

+# bunyan Changelog
+
+Known issues:
+
+- [issue #58] Can't install to a dir with spaces. This is [this node-gyp
+  bug](https://github.com/TooTallNate/node-gyp/issues/65).
+
+## not yet released
+
+(nothing yet)
+
+
+## 1.8.12
+
+- [issue #444] Fix the `bunyan` CLI to not duplicate the "HTTP/1.1 ..." status
+  line when serializing a "res" field.
+
+
+## 1.8.11
+
+- [issue #504] The `bunyan` 1.x CLI adds a `Host: $client_req.address[:$client_req.port]`
+  header when rendering a `client_req` field in a log record. Fix that here to:
+  (a) not add it if `client_req.headers` already includes a host header; and
+  (b) not include the given `port` if it is 80 or 443 (*assuming* that is the
+  default port.
+  Note: `bunyan` 2.x CLI will stop adding this Host header because it is a guess
+  that can be wrong and misleading.
+
+
+## 1.8.10
+
+- Ensure that `bunyan` errors out if attempting to use `-p PID` and
+  file args at the same time.
+
+
+## 1.8.9
+
+- [pull #409, issue #246] Revert a change added to the `bunyan` CLI version
+  1.0.1 where `SIGINT` was ignored, such that Ctrl+C could not be used to
+  terminate bunyan. (By @zbjornson and @davepacheco.)
+- [pull #469] Fix a strict mode (`"use strict;"`) error in some versions of
+  Safari.
+
+
+## 1.8.8
+
+- Fix breakage due to a silly last minute "fix 'make check'".
+
+
+## 1.8.7
+
+Note: *Bad release.* Use 1.8.8 or later.
+
+- [issue #484] Fix breakage due to #474 in previous release.
+
+
+## 1.8.6
+
+Note: *Bad release.* Use 1.8.7 or later.
+
+- [issue #474] Bunyan's `safeCycles` is too slow when logging large objects.
+
+
+## 1.8.5
+
+- [issue #401] Improved performance when using disabled log levels.
+
+
+## 1.8.4
+
+- [issue #454] Fix `src` usage with node v7.
+
+
+## 1.8.3
+
+- [issue #450] Fix `log.info(null)` crash that resulted from #426 in v1.8.2.
+
+
+## 1.8.2
+
+- [issue #449] Bump dtrace-provider dep to 0.7.0 to help avoid deprecation
+  warnings with node v6 in some cases.
+- [issue #426] Ensure `log.info({err: err})` results in a "msg" value, just
+  like `log.info(err)`.
+
+
+## 1.8.1
+
+- [pull #386] Fix bad bug in rotation that could cause a crash with
+  error message "cannot start a rotation when already rotating"
+  (by Frankie O'Rourke). The bug was introduced in 1.8.0.
+
+
+## 1.8.0
+
+Note: *Bad release.* An addition in this release broke 'rotating-file' usage.
+Use 1.8.1 or later.
+
+- [issue #370] Fix `bunyan -p ...` (i.e. DTrace integration) on node
+  4.x and 5.x.
+- [issue #329, pull #330] Update the 'rotating-file' stream to do a file
+  rotation on initialization if the mtime on the file path indicates the
+  last rotation time was missed -- i.e. if the app wasn't running at the
+  time. (by Paul Milham.)
+
+
+## 1.7.1
+
+- [issue #332, pull #355] Ensure stream for type='stream' stream is a writable
+  stream. (By Michael Nisi.)
+
+- [issue #344] Fix "rotating-file" Bunyan streams to not miss rotations when configured
+  for a period greater than approximately 25 days. Before this there was an issue
+  where periods greater than node.js's maximum `setTimeout` length would fail to rotate.
+  (By Martijn Schrage.)
+
+- [issue #234, pull #345] Improve `bunyan` CLI rendering of "res" field
+  HTTP responses to not show two blank lines for an empty body.
+  (By Michael Nisi.)
+
+
+## 1.7.0
+
+- [pull #311, #302, #310] Improve the runtime environment detection to fix
+  running under [NW.js](http://nwjs.io/). Contributions by Adam Lynch, Jeremy
+  Ruppel, and Aleksey Timchenko.
+
+- [pull #318] Add `reemitErrorEvents` optional boolean for streams added to a
+  Bunyan logger to control whether an "error" event on the stream will be
+  re-emitted on the `Logger` instance.
+
+        var log = bunyan.createLogger({
+            name: 'foo',
+            streams: [
+                {
+                    type: 'raw',
+                    stream: new MyCustomStream(),
+                    reemitErrorEvents: true
+                }
+            ]
+        });
+
+  Before this change, "error" events were re-emitted on [`file`
+  streams](https://github.com/trentm/node-bunyan#stream-type-file) only. The new
+  behaviour is as follows:
+
+    - `reemitErrorEvents` not specified: `file` streams will re-emit error events
+      on the Logger instance.
+    - `reemitErrorEvents: true`: error events will be re-emitted on the Logger
+      for any stream with a `.on()` function -- which includes file streams,
+      process.stdout/stderr, and any object that inherits from EventEmitter.
+    - `reemitErrorEvents: false`: error events will not be re-emitted for any
+      streams.
+
+  Dev Note: Bunyan `Logger` objects don't currently have a `.close()` method
+  in which registered error event handlers can be *un*registered. That means
+  that a (presumably rare) situation where code adds dozens of Bunyan Logger
+  streams to, e.g. process.stdout, and with `reemitErrorEvents: true`, could
+  result in leaking Logger objects.
+
+  Original work for allowing "error" re-emitting on non-file streams is
+  by Marc Udoff in pull #318.
+
+
+## 1.6.0
+
+- [pull #304, issue #245] Use [Moment.js][momentjs.com] library to handle
+  `bunyan` CLI time formatting in some cases, especially to fix display of
+  local time. It is now required for local time formatting (i.e. `bunyan -L`
+  or `bunyan --time local`). (By David M. Lee.)
+
+- [pull #252] Fix errant `client_res={}` in `bunyan` CLI rendering, and avoid
+  extra newlines in `client_req` rendering in some cases. (By Thomas Heymann.)
+
+- [pull #291, issue #303] Fix `LOG.child(...)` to *not* override the "hostname"
+  field of the parent. A use case is when one manually sets "hostname" to
+  something other than `os.hostname()`. (By github.com/Cactusbone.)
+
+- [issue #325] Allow one to set `level: 0` in `createLogger` to turn on
+  logging for all levels. (Adapted from #336 by github.com/sometimesalready.)
+
+- Add guards (to `resolveLevel`) so that all "level" values are validated.
+  Before this, a bogus level like "foo" or -12 or `['some', 'array']` would
+  silently be accepted -- with undefined results.
+
+- Doc updates for #340 and #305.
+
+- Update `make test` to test against node 5, 4, 0.12 and 0.10.
+
+
+## 1.5.1
+
+- [issue #296] Fix `src: true`, which was broken in v1.5.0.
+
+
+## 1.5.0
+
+Note: *Bad release.* The addition of `'use strict';` broke Bunyan's `src: true`
+feature. Use 1.5.1 instead.
+
+- [pull #236, issue #231, issue #223] Fix strict mode in the browser.
+- [pull #282, issue #213] Fixes bunyan to work with webpack. By Denis Izmaylov.
+- [pull #294] Update to dtrace-provider 0.6 to fix with node 4.0 and io.js 3.0.
+- Dropped support for 0.8 (can't install deps easily anymore for running
+  test suite). Bump to a recent iojs version for testing.
+
+
+## 1.4.0
+
+(Bumping minor ver b/c I'm wary of dtrace-provider changes. :)
+
+- [issue #258, pull #259] Update to dtrace-provider 0.5 to fix
+  install and tests on recent io.js versions.
+- safe-json-stringify@1.0.3 changed output, breaking some tests. Fix those.
+
+
+## 1.3.6
+
+- [issue #244] Make `bunyan` defensive on `res.header=null`.
+
+
+## 1.3.5
+
+- [issue #233] Make `bunyan` defensive on res.header as a boolean.
+- [issue #242] Make `bunyan` defensive on err.stack not being a string.
+
+
+## 1.3.4
+
+- Allow `log.child(...)` to work even if the logger is a *sub-class*
+  of Bunyan's Logger class.
+- [issue #219] Hide 'source-map-support' require from browserify.
+- [issue #218] Reset `haveNonRawStreams` on `<logger>.addStream`.
+
+
+## 1.3.3
+
+- [pull #127] Update to dtrace-provider 0.4.0, which gives io.js 1.x support
+  for dtrace-y parts of Bunyan.
+
+
+## 1.3.2
+
+- [pull #182] Fallback to using the optional 'safe-json-stringify' module
+  if `JSON.stringify` throws -- possibly with an enumerable property
+  getter than throws. By Martin Gausby.
+
+

+- [issue #164] Ensure a top-level `level` given in `bunyan.createLogger`
+  is *used* for given `streams`. For example, ensure that the following
+  results in the stream having a DEBUG level:
+
+        var log = bunyan.createLogger({
+            name: 'foo',
+            level: 'debug',
+            streams: [

+                }
+            ]
+        });
+
+  This was broken in the 1.0.1 release. Between that release and 1.3.0
+  the "/var/tmp/foo.log" stream would be at the INFO level (Bunyan's
+  default level).

+
+  Before this change, bunyan would throw. Now it emits a warning to stderr
+  *once*, and then silently ignores those log attempts, e.g.:
+
+        bunyan usage error: /Users/trentm/tm/node-bunyan/foo.js:12: attempt to log with an unbound log method: `this` is: { _events: { data: [Function] } }

+
+
+## 1.2.2
+
+- Drop the guard that a bunyan Logger level must be between TRACE (10)
+  and FATAL (60), inclusive. This allows a trick of setting the level

+## 1.0.0
+
+- [issue #87] **Backward incompatible change to `-c CODE`** improving
+  performance by over 10x (good!), with a backward incompatible change to
+  semantics (unfortunate), and adding some sugar (good!).
+
+  The `-c CODE` implementation was changed to use a JS function for processing
+  rather than `vm.runInNewContext`. The latter was specatularly slow, so
+  won't be missed. Unfortunately this does mean a few semantic differences in
+  the `CODE`, the most noticeable of which is that **`this` is required to
+  access the object fields:**
+
+        # Bad. Works with bunyan 0.x but not 1.x.
+        $ bunyan -c 'pid === 123' foo.log
+        ...
+
+        # Good. Works with all versions of bunyan
+        $ bunyan -c 'this.pid === 123' foo.log
+        ...
+
+  The old behaviour of `-c` can be restored with the `BUNYAN_EXEC=vm`
+  environment variable:
+
+        $ BUNYAN_EXEC=vm bunyan -c 'pid === 123' foo.log
+        ...
+
+  Some sugar was also added: the TRACE, DEBUG, ... constants are defined, so
+  one can:
+
+        $ bunyan -c 'this.level >= ERROR && this.component === "http"' foo.log
+        ...
+
+  And example of the speed improvement on a 10 MiB log example:
+
+        $ time BUNYAN_EXEC=vm bunyan -c 'this.level === ERROR' big.log | cat >slow
+
+        real    0m6.349s
+        user    0m6.292s
+        sys    0m0.110s
+
+        $ time bunyan -c 'this.level === ERROR' big.log | cat >fast
+
+        real    0m0.333s
+        user    0m0.303s
+        sys    0m0.028s
+
+  The change was courtesy Patrick Mooney (https://github.com/pfmooney). Thanks!
+
+- Add `bunyan -0 ...` shortcut for `bunyan -o bunyan ...`.
+
+- [issue #135] **Backward incompatible.** Drop dtrace-provider even from
+  `optionalDependencies`. Dtrace-provider has proven a consistent barrier to
+  installing bunyan, because it is a binary dep. Even as an *optional* dep it
+  still caused confusion and install noise.
+
+  Users of Bunyan on dtrace-y platforms (SmartOS, Mac, Illumos, Solaris) will
+  need to manually `npm install dtrace-provider` themselves to get [Bunyan's
+  dtrace support](https://github.com/trentm/node-bunyan#runtime-log-snooping-via-dtrace)
+  to work. If not installed, bunyan should stub it out properly.

+## 0.20.0
+
+- [Slight backward incompatibility] Fix serializer bug introduced in 0.18.3
+  (see below) to only apply serializers to log records when appropriate.
+
+  This also makes a semantic change to custom serializers. Before this change
+  a serializer function was called for a log record key when that value was
+  truth-y. The semantic change is to call the serializer function as long
+  as the value is not `undefined`. That means that a serializer function
+  should handle falsey values such as `false` and `null`.
+
+- Update to latest 'mv' dep (required for rotating-file support) to support
+  node v0.10.0.
+
+
+## 0.19.0
+
+**WARNING**: This release includes a bug introduced in bunyan 0.18.3 (see
+below). Please upgrade to bunyan 0.20.0.
+
+- [Slight backward incompatibility] Change the default error serialization
+  (a.k.a. `bunyan.stdSerializers.err`) to *not* serialize all additional
+  attributes of the given error object. This is an open door to unsafe logging
+  and logging should always be safe. With this change, error serialization
+  will log these attributes: message, name, stack, code, signal. The latter
+  two are added because some core node APIs include those fields (e.g.
+  `child_process.exec`).
+
+  Concrete examples where this has hurt have been the "domain" change
+  necessitating 0.18.3 and a case where
+  [node-restify](https://github.com/mcavage/node-restify) uses an error object
+  as the response object. When logging the `err` and `res` in the same log
+  statement (common for restify audit logging), the `res.body` would be JSON
+  stringified as '[Circular]' as it had already been emitted for the `err` key.
+  This results in a WTF with the bunyan CLI because the `err.body` is not
+  rendered.
+
+  If you need the old behaviour back you will need to do this:
+
+        var bunyan = require('bunyan');
+        var errSkips = {
+            // Skip domain keys. `domain` especially can have huge objects that can
+            // OOM your app when trying to JSON.stringify.
+            domain: true,
+            domain_emitter: true,
+            domain_bound: true,
+            domain_thrown: true
+        };
+        bunyan.stdSerializers.err = function err(err) {
+           if (!err || !err.stack)
+               return err;
+           var obj = {
+               message: err.message,
+               name: err.name,
+               stack: getFullErrorStack(err)
+           }
+           Object.keys(err).forEach(function (k) {
+               if (err[k] !== undefined && !errSkips[k]) {
+                   obj[k] = err[k];
+               }
+           });
+           return obj;
+         };
+
+- "long" and "bunyan" output formats for the CLI. `bunyan -o long` is the default
+  format, the same as before, just called "long" now instead of the cheesy "paul"
+  name. The "bunyan" output format is the same as "json-0", just with a more
+  convenient name.
+
+
+## 0.18.3
+
+**WARNING**: This release introduced a bug such that all serializers are
+applied to all log records even if the log record did not contain the key
+for that serializer. If a logger serializer function does not handle
+being given `undefined`, then you'll get warnings like this on stderr:
+
+    bunyan: ERROR: This should never happen. This is a bug in <https://github.com/trentm/node-bunyan> or in this application. Exception from "foo" Logger serializer: Error: ...
+        at Object.bunyan.createLogger.serializers.foo (.../myapp.js:20:15)
+        at Logger._applySerializers (.../lib/bunyan.js:644:46)
+        at Array.forEach (native)
+        at Logger._applySerializers (.../lib/bunyan.js:640:33)
+        ...
+
+and the following junk in written log records:
+
+    "foo":"(Error in Bunyan log "foo" serializer broke field. See stderr for details.)"
+
+Please upgrade to bunyan 0.20.0.
+
+
+- Change the `bunyan.stdSerializers.err` serializer for errors to *exclude*
+  [the "domain*" keys](http://nodejs.org/docs/latest/api/all.html#all_additions_to_error_objects).
+  `err.domain` will include its assigned members which can arbitrarily large
+  objects that are not intended for logging.
+
+- Make the "dtrace-provider" dependency optional. I hate to do this, but
+  installing bunyan on Windows is made very difficult with this as a required
+  dep.  Even though "dtrace-provider" stubs out for non-dtrace-y platforms,
+  without a compiler and Python around, node-gyp just falls over.
+
+
+## 0.18.2
+
+- [pull #67] Remove debugging prints in rotating-file support.
+  (by github.com/chad3814).
+- Update to dtrace-provider@0.2.7.
+
+
+## 0.18.1
+
+- Get the `bunyan` CLI to **not** automatically page (i.e. pipe to `less`)
+  if stdin isn't a TTY, or if following dtrace probe output (via `-p PID`),
+  or if not given log file arguments.
+
+
+## 0.18.0
+
+- Automatic paging support in the `bunyan` CLI (similar to `git log` et al).
+  IOW, `bunyan` will open your pager (by default `less`) and pipe rendered
+  log output through it. A main benefit of this is getting colored logs with
+  a pager without the pain. Before you had to explicit use `--color` to tell
+  bunyan to color output when the output was not a TTY:
+
+        bunyan foo.log --color | less -R        # before
+        bunyan foo.log                          # now
+
+  Disable with the `--no-pager` option or the `BUNYAN_NO_PAGER=1` environment
+  variable.
+
+  Limitations: Only supported for node >=0.8. Windows is not supported (at
+  least not yet).
+
+- Switch test suite to nodeunit (still using a node-tap'ish API via
+  a helper).
+
+
+## 0.17.0
+
+- [issue #33] Log rotation support:
+
+        var bunyan = require('bunyan');
+        var log = bunyan.createLogger({
+            name: 'myapp',
+            streams: [{
+                type: 'rotating-file',
+                path: '/var/log/myapp.log',
+                count: 7,
+                period: 'daily'
+            }]
+        });
+
+
+- Tweak to CLI default pretty output: don't special case "latency" field.
+  The special casing was perhaps nice, but less self-explanatory.
+  Before:
+
+        [2012-12-27T21:17:38.218Z]  INFO: audit/45769 on myserver: handled: 200 (15ms, audit=true, bar=baz)
+          GET /foo
+          ...
+
+  After:

+        [2012-12-27T21:17:38.218Z]  INFO: audit/45769 on myserver: handled: 200 (audit=true, bar=baz, latency=15)
+          GET /foo
+          ...
+
+- *Exit* CLI on EPIPE, otherwise we sit there useless processing a huge log
+  file with, e.g.  `bunyan huge.log | head`.
+
+
+## 0.16.8
+

+
+
+## 0.16.6
+
+- [issue #56] Support `bunyan -p NAME` to dtrace all PIDs matching 'NAME' in
+  their command and args (using `ps -A -o pid,command | grep NAME` or, on SunOS
+  `pgrep -lf NAME`). E.g.:
+
+        bunyan -p myappname
+
+  This is useful for usage of node's [cluster
+  module](http://nodejs.org/docs/latest/api/all.html#all_cluster) where you'll
+  have multiple worker processes.
+
+
+## 0.16.5
+
+- Allow `bunyan -p '*'` to capture bunyan dtrace probes from **all** processes.
+- issue #55: Add support for `BUNYAN_NO_COLOR` environment variable to
+  turn off all output coloring. This is still overridden by the `--color`
+  and `--no-color` options.
+
+
+## 0.16.4
+
+- issue #54: Ensure (again, see 0.16.2) that stderr from the dtrace child
+  process (when using `bunyan -p PID`) gets through. There had been a race
+  between exiting bunyan and the flushing of the dtrace process' stderr.
+
+
+## 0.16.3
+
+- Drop 'trentm-dtrace-provider' fork dep now that
+  <https://github.com/chrisa/node-dtrace-provider/pull/24> has been resolved.
+  Back to dtrace-provider.
+
+
+## 0.16.2
+
+- Ensure that stderr from the dtrace child process (when using `bunyan -p PID`)
+  gets through. The `pipe` usage wasn't working on SmartOS. This is important
+  to show the user if they need to 'sudo'.
+
+
+## 0.16.1
+
+- Ensure that a possible dtrace child process (with using `bunyan -p PID`) is
+  terminated on signal termination of the bunyan CLI (at least for SIGINT,
+  SIGQUIT, SIGTERM, SIGHUP).
+
+
+## 0.16.0
+
+- Add `bunyan -p PID` support. This is a convenience wrapper that effectively
+  calls:
+
+        dtrace -x strsize=4k -qn 'bunyan$PID:::log-*{printf("%s", copyinstr(arg0))}' | bunyan
+
+
+## 0.15.0
+
+- issue #48: Dtrace support! The elevator pitch is you can watch all logging
+  from all Bunyan-using process with something like this:
+
+        dtrace -x strsize=4k -qn 'bunyan*:::log-*{printf("%d: %s: %s", pid, probefunc, copyinstr(arg0))}'
+
+  And this can include log levels *below* what the service is actually configured
+  to log. E.g. if the service is only logging at INFO level and you need to see
+  DEBUG log messages, with this you can. Obviously this only works on dtrace-y
+  platforms: Illumos derivatives of SunOS (e.g. SmartOS, OmniOS), Mac, FreeBSD.
+
+  Or get the bunyan CLI to render logs nicely:
+
+        dtrace -x strsize=4k -qn 'bunyan*:::log-*{printf("%s", copyinstr(arg0))}' | bunyan
+
+  See <https://github.com/trentm/node-bunyan#dtrace-support> for details. By
+  Bryan Cantrill.
+
+
+## 0.14.6
+
+- Export `bunyan.safeCycles()`. This may be useful for custom `type == "raw"`
+  streams that may do JSON stringification of log records themselves. Usage:
+
+        var str = JSON.stringify(rec, bunyan.safeCycles());
+
+- [issue #49] Allow a `log.child()` to specify the level of inherited streams.

+        childLog.level('debug');
+
+        # After

+
+- Improve the Bunyan CLI crash message to make it easier to provide relevant
+  details in a bug report.
+
+
+## 0.14.5

+
+
+## 0.14.4

+- **Bad release. Use 0.14.5 instead.**
+- Improve error serialization to walk the chain of `.cause()` errors
+  from the likes of `WError` or `VError` error classes from

+- [pull #15] A new `bunyan.RingBuffer` stream class that is useful for
+  keeping the last N log messages in memory. This can be a fast way to keep
+  recent, and thus hopefully relevant, log messages. (by @dapsays,
+  github.com/davepacheco)
+
+  Potential uses: Live debugging if a running process could inspect those
+  messages. One could dump recent log messages at a finer log level than is
+  typically logged on
+  [`uncaughtException`](http://nodejs.org/docs/latest/api/all.html#all_event_uncaughtexception).
+
+        var ringbuffer = new bunyan.RingBuffer({ limit: 100 });
+        var log = new bunyan({
+            name: 'foo',
+            streams: [{
+                type: 'raw',
+                stream: ringbuffer,
+                level: 'debug'
+            }]
+        });
+
+        log.info('hello world');
+        console.log(ringbuffer.records);
+
+- Add support for "raw" streams. This is a logging stream that is given
+  raw log record objects instead of a JSON-stringified string.
+
+        function Collector() {
+            this.records = [];
+        }
+        Collector.prototype.write = function (rec) {
+            this.records.push(rec);
+        }
+        var log = new Logger({
+            name: 'mylog',
+            streams: [{
+                type: 'raw',
+                stream: new Collector()
+            }]
+        });
+
+  See "examples/raw-stream.js". I expect raw streams to be useful for
+  piping Bunyan logging to separate services (e.g. <http://www.loggly.com/>,
+  <https://github.com/etsy/statsd>) or to separate in-process handling.
+
+- Add test/corpus/*.log files (accidentally excluded) so the test suite

+
+
+## 0.8.0
+
+- [pull #21] Bunyan loggers now re-emit `fs.createWriteStream` error events.
+  By github.com/EvanOxfeld. See "examples/handle-fs-error.js" and

+            // Handle error writing to or creating FILENAME.
+        });
+
+- jsstyle'ing (via `make check`)
+
+
+## 0.7.0
+
+- [issue #12] Add `bunyan.createLogger(OPTIONS)` form, as is more typical in
+  node.js APIs.  This'll eventually become the preferred form.
+
+
+## 0.6.9
+
+- Change `bunyan` CLI default output to color "src" info red. Before the "src"
+  information was uncolored. The "src" info is the filename, line number and
+  function name resulting from using `src: true` in `Logger` creation. I.e.,
+  the `(/Users/trentm/tm/node-bunyan/examples/hi.js:10)` in:
+
+        [2012-04-10T22:28:58.237Z]  INFO: myapp/39339 on banana.local (/Users/trentm/tm/node-bunyan/examples/hi.js:10): hi
+
+- Tweak `bunyan` CLI default output to still show an "err" field if it doesn't
+  have a "stack" attribute.
+
+
+## 0.6.8
+
+- Fix bad bug in `log.child({...}, true);` where the added child fields **would
+  be added to the parent's fields**. This bug only existed for the "fast child"
+  path (that second `true` argument). A side-effect of fixing this is that
+  the "fast child" path is only 5 times as fast as the regular `log.child`,
+  instead of 10 times faster.
+
+
+## 0.6.7
+
+- [issue #6] Fix bleeding 'type' var to global namespace. (Thanks Mike!)
+
+
+## 0.6.6
+
+- Add support to the `bunyan` CLI taking log file path args, `bunyan foo.log`,
+  in addition to the usual `cat foo.log | bunyan`.
+- Improve reliability of the default output formatting of the `bunyan` CLI.
+  Before it could blow up processing log records missing some expected
+  fields.
+
+
+## 0.6.5
+
+- ANSI coloring output from `bunyan` CLI tool (for the default output mode/style).
+  Also add the '--color' option to force coloring if the output stream is not
+  a TTY, e.g. `cat my.log | bunyan --color | less -R`. Use `--no-color` to
+  disable coloring, e.g. if your terminal doesn't support ANSI codes.
+- Add 'level' field to log record before custom fields for that record. This
+  just means that the raw record JSON will show the 'level' field earlier,
+  which is a bit nicer for raw reading.
+
+
+## 0.6.4
+
+- [issue #5] Fix `log.info() -> boolean` to work properly. Previous all were
+  returning false. Ditto all trace/debug/.../fatal methods.
+
+
+## 0.6.3
+
+- Allow an optional `msg` and arguments to the `log.info(<Error> err)` logging
+  form. For example, before:
+
+        log.debug(my_error_instance)            // good
+        log.debug(my_error_instance, "boom!")   // wasn't allowed
+
+  Now the latter is allowed if you want to expliciting set the log msg. Of course
+  this applies to all the `log.{trace|debug|info...}()` methods.
+
+- `bunyan` cli output: clarify extra fields with quoting if empty or have
+  spaces. E.g. 'cmd' and 'stderr' in the following:
+
+        [2012-02-12T00:30:43.736Z] INFO: mo-docs/43194 on banana.local: buildDocs results (req_id=185edca2-2886-43dc-911c-fe41c09ec0f5, route=PutDocset, error=null, stderr="", cmd="make docs")
+
+
+## 0.6.2
+
+- Fix/guard against unintended inclusion of some files in npm published package
+  due to <https://github.com/isaacs/npm/issues/2144>
+
+
+## 0.6.1
+
+- Internal: starting jsstyle usage.
+- Internal: add .npmignore. Previous packages had reams of bunyan crud in them.
+
+
+## 0.6.0
+
+- Add 'pid' automatic log record field.
+
+
+## 0.5.3
+
+- Add 'client_req' (HTTP client request) standard formatting in `bunyan` CLI
+  default output.
+- Improve `bunyan` CLI default output to include *all* log record keys. Unknown keys
+  are either included in the first line parenthetical (if short) or in the indented
+  subsequent block (if long or multiline).
+
+
+## 0.5.2
+
+- [issue #3] More type checking of `new Logger(...)` and `log.child(...)`
+  options.
+- Start a test suite.
+
+
+## 0.5.1
+
+- [issue #2] Add guard on `JSON.stringify`ing of log records before emission.
+  This will prevent `log.info` et al throwing on record fields that cannot be
+  represented as JSON. An error will be printed on stderr and a clipped log
+  record emitted with a 'bunyanMsg' key including error details. E.g.:
+
+        bunyan: ERROR: could not stringify log record from /Users/trentm/tm/node-bunyan/examples/unstringifyable.js:12: TypeError: Converting circular structure to JSON
+        {
+          "name": "foo",
+          "hostname": "banana.local",
+          "bunyanMsg": "bunyan: ERROR: could not stringify log record from /Users/trentm/tm/node-bunyan/examples/unstringifyable.js:12: TypeError: Converting circular structure to JSON",
+        ...
+
+  Some timing shows this does effect log speed:
+
+        $ node tools/timeguard.js     # before
+        Time try/catch-guard on JSON.stringify:
+         - log.info:  0.07365ms per iteration
+        $ node tools/timeguard.js     # after
+        Time try/catch-guard on JSON.stringify:
+         - log.info:  0.07368ms per iteration
+
+
+## 0.5.0
+
+- Use 10/20/... instead of 1/2/... for level constant values. Ostensibly this
+  allows for intermediary levels from the defined "trace/debug/..." set.
+  However, that is discouraged. I'd need a strong user argument to add
+  support for easily using alternative levels. Consider using a separate
+  JSON field instead.
+- s/service/name/ for Logger name field. "service" is unnecessarily tied
+  to usage for a service. No need to differ from log4j Logger "name".
+- Add `log.level(...)` and `log.levels(...)` API for changing logger stream
+  levels.
+- Add `TRACE|DEBUG|INFO|WARN|ERROR|FATAL` level constants to exports.
+- Add `log.info(err)` special case for logging an `Error` instance. For
+  example `log.info(new TypeError("boom")` will produce:
+
+        ...
+        "err": {
+          "message": "boom",
+          "name": "TypeError",
+          "stack": "TypeError: boom\n    at Object.<anonymous> ..."
+        },
+        "msg": "boom",
+        ...
+
+
+## 0.4.0
+
+- Add `new Logger({src: true})` config option to have a 'src' attribute be
+  automatically added to log records with the log call source info. Example:
+
+        "src": {
+          "file": "/Users/trentm/tm/node-bunyan/examples/src.js",
+          "line": 20,
+          "func": "Wuzzle.woos"
+        },
+
+
+## 0.3.0
+
+- `log.child(options[, simple])` Added `simple` boolean arg. Set `true` to
+  assert that options only add fields (no config changes). Results in a 10x
+  speed increase in child creation. See "tools/timechild.js". On my Mac,
+  "fast child" creation takes about 0.001ms. IOW, if your app is dishing
+  10,000 req/s, then creating a log child for each request will take
+  about 1% of the request time.
+- `log.clone` -> `log.child` to better reflect the relationship: streams and
+  serializers are inherited. Streams can't be removed as part of the child
+  creation. The child doesn't own the parent's streams (so can't close them).
+- Clean up Logger creation. The goal here was to ensure `log.child` usage
+  is fast. TODO: measure that.
+- Add `Logger.stdSerializers.err` serializer which is necessary to get good
+  Error object logging with node 0.6 (where core Error object properties
+  are non-enumerable).
+
+
+## 0.2.0
+
+- Spec'ing core/recommended log record fields.
+- Add `LOG_VERSION` to exports.
+- Improvements to request/response serializations.
+
+
+## 0.1.0
+
+First release.

+# Contributing to node-bunyan
+
+Thanks for using node-bunyan and for considering contributing to it! Or perhaps
+you are just here to get a sniff for what is going on with node-bunyan
+development.
+
+
+## How you can help
+
+If you want to help me here, great! Thank you! Some ideas:
+
+- Do you have experience with and/or recommendations for a good automated
+  testing service? Ideally I'd like support for Mac, Linux, SmartOS, and maybe
+  Windows. Also, support for node.js versions 0.10 up to whatever the current
+  latest is. Are those too tall an order? What's more, Bunyan is meant to work
+  (at least partially) in the browser. Is there a good service for that?
+  Please discuss on [issue #342](https://github.com/trentm/node-bunyan/issues/342).
+
+- Fielding issues labelled with "[Type-Question][Type-Question]", if you are familiar
+  with Bunyan and know how to answer them, would be great.
+
+- If you want to dive into code, but aren't *that* familiar with node-bunyan,
+  then [issues labelled with Experience-Easy][Experience-Easy] are a good
+  place to start.
+
+- [Once I've made a once over
+  triaging](https://github.com/trentm/node-bunyan/issues/335) and consolodating
+  issues and PRs, volunteering for issues in a particular
+  [component](#component) with which you have familiarity would be great.
+
+[Type-Question]: https://github.com/trentm/node-bunyan/issues?q=is%3Aopen+is%3Aissue+label%3AType-Question
+
+
+## Trent's Biased Rules for Code
+
+In the hope that it makes it easier to get PRs into Bunyan, here is my biased
+list of what I typically want. Submitting a PR without all of these is
+*totally fine*! The only side-effect is that it may take longer for me to
+provide feedback on it and merge it. I'll politely request missing pieces.
+
+
+- Please follow existing code style. Contributed code must pass `make check`.
+  (Note: I intended to [change to eslint
+  soon](https://github.com/trentm/node-bunyan/issues/341), so currently `make
+  check` might be a moving target.)
+
+- Any user visible change in behaviour should almost certainly include an
+  update to the docs. Currently the "docs" is the README.md.
+
+- Adding a test case for code changes is **stronly recommended**, else I
+  can't easily promise to not break your fix/feature later. If you don't
+  grok the test suite, please ask. We can use it to form the basis for a
+  "test/README.md".
+
+- Typically a code change should have an associated issue or PR. This allows
+  addition of follow-up issues, discussion, test data, etc. to be associated
+  with the commit. Just using GitHub pull requests makes this easy.
+
+- All but the most trivial code changes should have an addition to the
+  [changelog](./CHANGES.md). The audience for the changelog is *Bunyan users*.
+  However, because rebasing longer-lived PRs against master is a pain
+  with a change to CHANGES.md, please **do not include a CHANGES.md change
+  in your PR. Instead suggest a CHANGES.md addition in a comment on the
+  PR.**
+
+- Good commit messages, please:
+    - The first line should be a succinct summary of the issue or fix. A
+      good candidate is to just cut 'n paste the issue title, if there is one.
+    - If the commit is for a particular issue/PR (see previous rule), please
+      list the issue number in the commit message. E.g. "Fixes #123" or "Related
+      to #234".
+    - The audience for commit messages is *Bunyan developers*.
+
+
+## Pull Request Lifecycle
+
+(Language adapted from
+[terraform](https://github.com/hashicorp/terraform/blob/master/CONTRIBUTING.md).)
+
+- You are welcome to submit your pull request for commentary or review before it
+  is fully completed. Please prefix the title of your pull request with "[WIP]"
+  to indicate this. It's also a good idea to include specific questions or items
+  you'd like feedback on.
+
+- Once you believe your pull request is ready to be merged, you can remove any
+  "[WIP]" prefix from the title and a core team member will review. See
+  Trent's Biased Rules above to help ensure that your contribution will be
+  merged quickly.
+
+- Trent or, if things go well, a node-bunyan maintainer will look over your
+  contribution and either provide comments letting you know if there is anything
+  left to do. Please be patient. Unfortunately, I'm not able to carve out
+  a *lot* of time for Bunyan development and maintenance.
+
+- Once all outstanding comments and checklist items have been addressed, your
+  contribution will be merged. Merged PRs will be included in the next
+  node-bunyan release.
+
+- In some cases, we might decide that a PR should be closed. We'll make sure to
+  provide clear reasoning when this happens.
+
+
+## Issue labels
+
+The point of issue labeling for node-bunyan is to help answer "what should be
+worked on now? what can be left for later?" I don't want issue labelling to
+become a burden for anyone, so (a) don't feel obliged to add them yourself and
+(b) I'm happy to reevaluate their usage.
+
+Bunyan shall have categories of [issue
+labels](https://github.com/trentm/node-bunyan/labels) named "$category-$value".
+An issue should have max *one* label from each set. Users of Google Code's
+dearly departed issue tracker may remember this kind of thing. This is a
+poorman's version of structured issue tracker metadata.
+
+I'm inclined to *not* do priorities right now. *Possibly* we'll use GitHub
+milestones to basically set targets for upcoming releases. But otherwise my
+sense is that for smaller OSS projects, assigning prios will get in the way.
+If people would think it helpful, I'd consider "Difficulty-" or "Experience-"
+categories (a la Rust's "E-" labels) to mark easier and intermediate tasks
+that someone interested but maybe not very familiar with Bunyan might want
+to tackle.
+
+For now, here are the various labels and their purpose:
+
+### Meta
+
+- needstriage: Temporary label to help me do a single triage pass through all
+  current open issues and PRs.
+  See [#335](https://github.com/trentm/node-bunyan/issues/335)
+  where I'm working through this.
+
+### Type
+
+Color: green
+
+- Type-Unknown: If it is still unclear or undecided if an issue is an intended
+  feature (perhaps arguing for better docs or examples to avoid confusion) or a
+  bug, I will use this category.
+- Type-Question: Asking a question on Bunyan usage, about the project, etc.
+- Type-Bug: A bug in Bunyan's behaviour.
+- Type-Improvement: A new feature or other improvement.
+- Type-Doc: Issues with Bunyan's documentation.
+- Type-Task: A project task to be done.
+
+TODO: consider Type-Unknown for the "unclear if bug or feature" tickets.
+
+### Component
+
+Color: blue
+
+- Component-Project: Project meta stuff like testing, linting, build, install,
+  etc.
+- Component-CLI: The `bunyan` command-line tool.
+- Component-Lib: catch-all for other library stuff
+    - Component-LibRotation: The bunyan library's log rotation support.
+    - Component-LibBrowser: Bunyan's handling/support for running in the browser.
+    - Component-LibFlush: A separate component for collecting the tickets related
+      to closing/flushing bunyan streams on process shutdown.
+
+The point of components is to find like issues to help with reference, search
+and resolving them. If no component fits an issue/PR, then don't add a label.
+
+### Resolution
+
+Color: red
+
+- Resolution-WontFix
+- Resolution-Duplicate
+- Resolution-Fixed: Also used to indicate "doc written", "question answered",
+  "feature implemented".
+- Resolution-CannotRepro: After some reasonable attempt by maintainers to
+  reproduce a bug report, I want it to be non-controversial to close it
+  and mark it with this. If given more info by someone able to repro, we
+  can happy re-open issues.
+
+### Experience
+
+Color: yellow
+
+- Experience-Easy: Relatively little experience with node-bunyan should be
+  required to complete this issue.
+- Experience-NeedsTest: Typically added to an issue or PR that needs a test
+  case. Someone familiar enough with node-bunyan's test suite could tackle this.
+- Experience-Hard: At a guess, this is a thorny issue that requires known
+  node-bunyan well, knowing node.js well, requires design review or all of
+  these.
+
+One of the "Experience-\*" labels can optionally be put on an issue or PR to
+indicate what kind of experience a contributor would need with node-bunyan
+(and/or node.js) to complete it. For example, if you're looking for somewhere to
+start, check out the [Experience-Easy][Experience-Easy] tag. This category idea
+is borrowed from [rust's E-\* labels][rust-issue-triage].
+
+[Experience-Easy]: https://github.com/trentm/node-bunyan/issues?q=is%3Aopen+is%3Aissue+label%3AExperience-Easy
+[rust-issue-triage]: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#issue-triage

+Bunyan is **a simple and fast JSON logging library** for node.js services:
+
+```js
+var bunyan = require('bunyan');
+var log = bunyan.createLogger({name: "myapp"});
+log.info("hi");
+```
+
+and **a `bunyan` CLI tool** for nicely viewing those logs:
+
+![bunyan CLI screenshot](https://raw.github.com/trentm/node-bunyan/master/tools/screenshot1.png)
+
+Manifesto: Server logs should be structured. JSON's a good format. Let's do
+that. A log record is one line of `JSON.stringify`'d output. Let's also
+specify some common names for the requisite and common fields for a log
+record (see below).

+
+# Current Status
+
+Solid core functionality is there. Joyent is using this for a number of
+production services. Bunyan supports node 0.10 and greater. Follow
+<a href="https://twitter.com/intent/user?screen_name=trentmick" target="_blank">@trentmick</a>
+for updates to Bunyan.
+
+There is an email discussion list
+[bunyan-logging@googlegroups.com](mailto:bunyan-logging@googlegroups.com),
+also [as a forum in the
+browser](https://groups.google.com/forum/?fromgroups#!forum/bunyan-logging).
+
+
+# Installation
+
+```sh
+npm install bunyan
+```
+
+**Tip**: The `bunyan` CLI tool is written to be compatible (within reason) with
+all versions of Bunyan logs. Therefore you might want to `npm install -g bunyan`
+to get the bunyan CLI on your PATH, then use local bunyan installs for
+node.js library usage of bunyan in your apps.
+
+
+# Features
+
+- elegant [log method API](#log-method-api)
+- extensible [streams](#streams) system for controlling where log records
+  go (to a stream, to a file, [log file rotation](#stream-type-rotating-file),
+  etc.)
+- [`bunyan` CLI](#cli-usage) for pretty-printing and filtering of Bunyan logs

+
+
+# Introduction
+
+Like most logging libraries you create a Logger instance and call methods
+named after the logging levels:
+
+```js
+// hi.js
+var bunyan = require('bunyan');
+var log = bunyan.createLogger({name: 'myapp'});
+log.info('hi');
+log.warn({lang: 'fr'}, 'au revoir');
+```
+
+All loggers must provide a "name". This is somewhat akin to the log4j logger
+"name", but Bunyan doesn't do hierarchical logger names.
+
+**Bunyan log records are JSON.** A few fields are added automatically:
+"pid", "hostname", "time" and "v".
+
+```sh
+$ node hi.js
+{"name":"myapp","hostname":"banana.local","pid":40161,"level":30,"msg":"hi","time":"2013-01-04T18:46:23.851Z","v":0}
+{"name":"myapp","hostname":"banana.local","pid":40161,"level":40,"lang":"fr","msg":"au revoir","time":"2013-01-04T18:46:23.853Z","v":0}
+```
+
+
+## Constructor API
+
+```js
+var bunyan = require('bunyan');
+var log = bunyan.createLogger({
+    name: <string>,                     // Required
+    level: <level name or number>,      // Optional, see "Levels" section
+    stream: <node.js stream>,           // Optional, see "Streams" section
+    streams: [<bunyan streams>, ...],   // Optional, see "Streams" section
+    serializers: <serializers mapping>, // Optional, see "Serializers" section
+    src: <boolean>,                     // Optional, see "src" section
+
+    // Any other fields are added to all log records as is.
+    foo: 'bar',
+    ...
+});
+```
+
+
+## Log Method API
+
+The example above shows two different ways to call `log.info(...)`. The
+full API is:
+
+```js
+log.info();     // Returns a boolean: is the "info" level enabled?
+                // This is equivalent to `log.isInfoEnabled()` or
+                // `log.isEnabledFor(INFO)` in log4j.
+
+log.info('hi');                     // Log a simple string message (or number).
+log.info('hi %s', bob, anotherVar); // Uses `util.format` for msg formatting.
+
+log.info({foo: 'bar'}, 'hi');
+                // The first field can optionally be a "fields" object, which
+                // is merged into the log record.
+
+log.info(err);  // Special case to log an `Error` instance to the record.
+                // This adds an "err" field with exception details
+                // (including the stack) and sets "msg" to the exception
+                // message.
+log.info(err, 'more on this: %s', more);
+                // ... or you can specify the "msg".
+
+log.info({foo: 'bar', err: err}, 'some msg about this error');
+                // To pass in an Error *and* other fields, use the `err`
+                // field name for the Error instance.
+```
+
+Note that this implies **you cannot blindly pass any object as the first
+argument to log it** because that object might include fields that collide with
+Bunyan's [core record fields](#core-fields). In other words,
+`log.info(mywidget)` may not yield what you expect. Instead of a string
+representation of `mywidget` that other logging libraries may give you, Bunyan
+will try to JSON-ify your object. It is a Bunyan best practice to always give a
+field name to included objects, e.g.:
+
+```js
+log.info({widget: mywidget}, ...)
+```
+
+This will dove-tail with [Bunyan serializer support](#serializers), discussed
+later.
+
+The same goes for all of Bunyan's log levels: `log.trace`, `log.debug`,
+`log.info`, `log.warn`, `log.error`, and `log.fatal`. See the [levels
+section](#levels) below for details and suggestions.
+
+
+## CLI Usage
+
+Bunyan log output is a stream of JSON objects. This is great for processing,
+but not for reading directly. A **`bunyan` tool** is provided **for
+pretty-printing bunyan logs** and for **filtering** (e.g.
+`| bunyan -c 'this.foo == "bar"'`). Using our example above:
+
+```sh
+$ node hi.js | ./node_modules/.bin/bunyan
+[2013-01-04T19:01:18.241Z]  INFO: myapp/40208 on banana.local: hi
+[2013-01-04T19:01:18.242Z]  WARN: myapp/40208 on banana.local: au revoir (lang=fr)
+```
+
+See the screenshot above for an example of the default coloring of rendered
+log output. That example also shows the nice formatting automatically done for
+some well-known log record fields (e.g. `req` is formatted like an HTTP request,
+`res` like an HTTP response, `err` like an error stack trace).
+
+One interesting feature is **filtering** of log content, which can be useful
+for digging through large log files or for analysis. We can filter only
+records above a certain level:
+
+```sh
+$ node hi.js | bunyan -l warn
+[2013-01-04T19:08:37.182Z]  WARN: myapp/40353 on banana.local: au revoir (lang=fr)
+```
+
+Or filter on the JSON fields in the records (e.g. only showing the French
+records in our contrived example):
+
+```sh
+$ node hi.js | bunyan -c 'this.lang == "fr"'
+[2013-01-04T19:08:26.411Z]  WARN: myapp/40342 on banana.local: au revoir (lang=fr)
+```
+
+See `bunyan --help` for other facilities.
+
+
+## Streams Introduction
+
+By default, log output is to stdout and at the "info" level. Explicitly that
+looks like:
+
+```js
+var log = bunyan.createLogger({
+    name: 'myapp',
+    stream: process.stdout,
+    level: 'info'
+});
+```
+
+That is an abbreviated form for a single stream. **You can define multiple
+streams at different levels**.
+
+```js
+var log = bunyan.createLogger({
+  name: 'myapp',
+  streams: [
+    {
+      level: 'info',
+      stream: process.stdout            // log INFO and above to stdout
+    },
+    {
+      level: 'error',
+      path: '/var/tmp/myapp-error.log'  // log ERROR and above to a file
+    }
+  ]
+});
+```
+
+More on streams in the [Streams section](#streams) below.
+
+## log.child
+
+Bunyan has a concept of a child logger to **specialize a logger for a
+sub-component of your application**, i.e. to create a new logger with
+additional bound fields that will be included in its log records. A child
+logger is created with `log.child(...)`.
+
+In the following example, logging on a "Wuzzle" instance's `this.log` will
+be exactly as on the parent logger with the addition of the `widget_type`
+field:
+
+```js
+var bunyan = require('bunyan');
+var log = bunyan.createLogger({name: 'myapp'});
+
+function Wuzzle(options) {
+    this.log = options.log.child({widget_type: 'wuzzle'});
+    this.log.info('creating a wuzzle')
+}
+Wuzzle.prototype.woos = function () {
+    this.log.warn('This wuzzle is woosey.')
+}
+
+log.info('start');
+var wuzzle = new Wuzzle({log: log});
+wuzzle.woos();
+log.info('done');
+```
+
+Running that looks like (raw):
+
+```sh
+$ node myapp.js
+{"name":"myapp","hostname":"myhost","pid":34572,"level":30,"msg":"start","time":"2013-01-04T07:47:25.814Z","v":0}
+{"name":"myapp","hostname":"myhost","pid":34572,"widget_type":"wuzzle","level":30,"msg":"creating a wuzzle","time":"2013-01-04T07:47:25.815Z","v":0}
+{"name":"myapp","hostname":"myhost","pid":34572,"widget_type":"wuzzle","level":40,"msg":"This wuzzle is woosey.","time":"2013-01-04T07:47:25.815Z","v":0}
+{"name":"myapp","hostname":"myhost","pid":34572,"level":30,"msg":"done","time":"2013-01-04T07:47:25.816Z","v":0}
+```
+
+And with the `bunyan` CLI (using the "short" output mode):
+
+```sh
+$ node myapp.js  | bunyan -o short
+07:46:42.707Z  INFO myapp: start
+07:46:42.709Z  INFO myapp: creating a wuzzle (widget_type=wuzzle)
+07:46:42.709Z  WARN myapp: This wuzzle is woosey. (widget_type=wuzzle)
+07:46:42.709Z  INFO myapp: done
+```
+
+A more practical example is in the
+[node-restify](https://github.com/mcavage/node-restify) web framework.
+Restify uses Bunyan for its logging. One feature of its integration, is that
+if `server.use(restify.requestLogger())` is used, each restify request handler
+includes a `req.log` logger that is:
+
+```js
+log.child({req_id: <unique request id>}, true)
+```
+
+Apps using restify can then use `req.log` and have all such log records
+include the unique request id (as "req\_id"). Handy.
+
+
+## Serializers
+
+Bunyan has a concept of **"serializer" functions to produce a JSON-able object
+from a JavaScript object**, so you can easily do the following:
+
+```js
+log.info({req: <request object>}, 'something about handling this request');
+```
+
+and have the `req` entry in the log record be just a reasonable subset of
+`<request object>` fields (or computed data about those fields).
+
+
+A logger instance can have a `serializers` mapping of log record field name
+("req" in this example) to a serializer function. When creating the log
+record, Bunyan will call the serializer function for fields of that name.
+An example:
+
+```js
+function reqSerializer(req) {
+    return {
+        method: req.method,
+        url: req.url,
+        headers: req.headers
+    };
+}
+var log = bunyan.createLogger({
+    name: 'myapp',
+    serializers: {
+        req: reqSerializer
+    }
+});
+```
+
+
+Typically serializers are added to a logger at creation time via
+`bunyan.createLogger({..., serializers: <serializers>})`. However, serializers
+can be added after creation via `<logger>.addSerializers(...)`, e.g.:
+
+```js
+var log = bunyan.createLogger({name: 'myapp'});
+log.addSerializers({req: reqSerializer});
+```
+
+### Requirements for serializers functions
+
+A serializer function is passed unprotected objects that are passed to the
+`log.info`, `log.debug`, etc. call. This means a poorly written serializer
+function can case side-effects. Logging shouldn't do that. Here are a few
+rules and best practices for serializer functions:
+
+- A serializer function *should never throw*. The bunyan library *does*
+  protect somewhat from this: if the serializer throws an error, then
+  bunyan will (a) write an ugly message on stderr (along with the traceback),
+  and (b) the field in the log record will be replace with a short error message.
+  For example:
+
+    ```
+    bunyan: ERROR: Exception thrown from the "foo" Bunyan serializer. This should never happen. This is a bug in that serializer function.
+    TypeError: Cannot read property 'not' of undefined
+        at Object.fooSerializer [as foo] (/Users/trentm/tm/node-bunyan/bar.js:8:26)
+        at /Users/trentm/tm/node-bunyan/lib/bunyan.js:873:50
+        at Array.forEach (native)
+        at Logger._applySerializers (/Users/trentm/tm/node-bunyan/lib/bunyan.js:865:35)
+        at mkRecord (/Users/trentm/tm/node-bunyan/lib/bunyan.js:978:17)
+        at Logger.info (/Users/trentm/tm/node-bunyan/lib/bunyan.js:1044:19)
+        at Object.<anonymous> (/Users/trentm/tm/node-bunyan/bar.js:13:5)
+        at Module._compile (module.js:409:26)
+        at Object.Module._extensions..js (module.js:416:10)
+        at Module.load (module.js:343:32)
+    {"name":"bar","hostname":"danger0.local","pid":47411,"level":30,"foo":"(Error in Bunyan log \"foo\" serializer broke field. See stderr for details.)","msg":"one","time":"2017-03-08T02:53:51.173Z","v":0}
+    ```
+
+- A serializer function *should never mutate the given object*. Doing so will
+  change the object in your application.
+
+- A serializer function *should be defensive*. In my experience it is common to
+  set a serializer in an app, say for field name "foo", and then accidentally
+  have a log line that passes a "foo" that is undefined, or null, or of some
+  unexpected type. A good start at defensiveness is to start with this:
+
+    ```javascript
+    function fooSerializers(foo) {
+        // Guard against foo be null/undefined. Check that expected fields
+        // are defined.
+        if (!foo || !foo.bar)
+            return foo;
+        var obj = {
+            // Create the object to be logged.
+            bar: foo.bar
+        }
+        return obj;
+    };
+    ```
+
+
+### Standard Serializers
+
+Bunyan includes a small set of "standard serializers", exported as
+`bunyan.stdSerializers`. Their use is completely optional. Example using
+all of them:
+
+```js
+var log = bunyan.createLogger({
+    name: 'myapp',
+    serializers: bunyan.stdSerializers
+});
+```
+
+or particular ones:
+
+```js
+var log = bunyan.createLogger({
+    name: 'myapp',
+    serializers: {err: bunyan.stdSerializers.err}
+});
+```
+
+Standard serializers are:
+
+| Field | Description |
+| ----- | ----------- |
+| err   | Used for serializing JavaScript error objects, including traversing an error's cause chain for error objects with a `.cause()` -- e.g. as from [verror](https://github.com/davepacheco/node-verror). |
+| req   | Common fields from a node.js HTTP request object. |
+| res   | Common fields from a node.js HTTP response object. |
+
+Note that the `req` and `res` serializers intentionally do not include the
+request/response *body*, as that can be prohibitively large. If helpful, the
+[restify framework's audit logger plugin](https://github.com/restify/node-restify/blob/ac13902ad9716dcb20aaa62295403983075b1841/lib/plugins/audit.js#L38-L87)
+has its own req/res serializers that include more information (optionally
+including the body).
+
+
+## src
+
+The **source file, line and function of the log call site** can be added to
+log records by using the `src: true` config option:
+
+```js
+var log = bunyan.createLogger({src: true, ...});
+```
+
+This adds the call source info with the 'src' field, like this:
+
+```js
+{
+  "name": "src-example",
+  "hostname": "banana.local",
+  "pid": 123,
+  "component": "wuzzle",
+  "level": 4,
+  "msg": "This wuzzle is woosey.",
+  "time": "2012-02-06T04:19:35.605Z",
+  "src": {
+    "file": "/Users/trentm/tm/node-bunyan/examples/src.js",
+    "line": 20,
+    "func": "Wuzzle.woos"
+  },
+  "v": 0
+}
+```
+
+**WARNING: Determining the call source info is slow. Never use this option
+in production.**
+
+
+# Levels
+
+The log levels in bunyan are as follows. The level descriptions are best
+practice *opinions* of the author.
+
+- "fatal" (60): The service/app is going to stop or become unusable now.
+  An operator should definitely look into this soon.
+- "error" (50): Fatal for a particular request, but the service/app continues
+  servicing other requests. An operator should look at this soon(ish).
+- "warn" (40): A note on something that should probably be looked at by an
+  operator eventually.
+- "info" (30): Detail on regular operation.
+- "debug" (20): Anything else, i.e. too verbose to be included in "info" level.
+- "trace" (10): Logging from external libraries used by your app or *very*
+  detailed application logging.
+
+Setting a logger instance (or one of its streams) to a particular level implies
+that all log records *at that level and above* are logged. E.g. a logger set to
+level "info" will log records at level info and above (warn, error, fatal).
+
+While using log level *names* is preferred, the actual level values are integers
+internally (10 for "trace", ..., 60 for "fatal"). Constants are defined for
+the levels: `bunyan.TRACE` ... `bunyan.FATAL`. The lowercase level names are
+aliases supported in the API, e.g. `log.level("info")`. There is one exception:
+DTrace integration uses the level names. The fired DTrace probes are named
+'bunyan-$levelName'.
+
+Here is the API for querying and changing levels on an existing logger.
+Recall that a logger instance has an array of output "streams":
+
+```js
+log.level() -> INFO   // gets current level (lowest level of all streams)
+
+log.level(INFO)       // set all streams to level INFO
+log.level("info")     // set all streams to level INFO
+
+log.levels() -> [DEBUG, INFO]   // get array of levels of all streams
+log.levels(0) -> DEBUG          // get level of stream at index 0
+log.levels("foo")               // get level of stream with name "foo"
+
+log.levels(0, INFO)             // set level of stream 0 to INFO
+log.levels(0, "info")           // can use "info" et al aliases
+log.levels("foo", WARN)         // set stream named "foo" to WARN
+```
+
+
+## Level suggestions
+
+Trent's biased suggestions for server apps: Use "debug" sparingly. Information
+that will be useful to debug errors *post mortem* should usually be included in
+"info" messages if it's generally relevant or else with the corresponding
+"error" event. Don't rely on spewing mostly irrelevant debug messages all the
+time and sifting through them when an error occurs.
+
+Trent's biased suggestions for node.js libraries: IMHO, libraries should only
+ever log at `trace`-level. Fine control over log output should be up to the
+app using a library. Having a library that spews log output at higher levels
+gets in the way of a clear story in the *app* logs.
+
+
+# Log Record Fields
+
+This section will describe *rules* for the Bunyan log format: field names,
+field meanings, required fields, etc. However, a Bunyan library doesn't
+strictly enforce all these rules while records are being emitted. For example,
+Bunyan will add a `time` field with the correct format to your log records,
+but you can specify your own. It is the caller's responsibility to specify
+the appropriate format.
+
+The reason for the above leniency is because IMO logging a message should
+never break your app. This leads to this rule of logging: **a thrown
+exception from `log.info(...)` or equivalent (other than for calling with the
+incorrect signature) is always a bug in Bunyan.**
+
+
+A typical Bunyan log record looks like this:
+
+```js
+{"name":"myserver","hostname":"banana.local","pid":123,"req":{"method":"GET","url":"/path?q=1#anchor","headers":{"x-hi":"Mom","connection":"close"}},"level":3,"msg":"start request","time":"2012-02-03T19:02:46.178Z","v":0}
+```
+
+Pretty-printed:
+
+```js
+{
+  "name": "myserver",
+  "hostname": "banana.local",
+  "pid": 123,
+  "req": {
+    "method": "GET",
+    "url": "/path?q=1#anchor",
+    "headers": {
+      "x-hi": "Mom",
+      "connection": "close"
+    },
+    "remoteAddress": "120.0.0.1",
+    "remotePort": 51244
+  },
+  "level": 3,
+  "msg": "start request",
+  "time": "2012-02-03T19:02:57.534Z",
+  "v": 0
+}
+```
+
+## Core fields
+
+- `v`: Required. Integer. Added by Bunyan. Cannot be overridden.
+  This is the Bunyan log format version (`require('bunyan').LOG_VERSION`).
+  The log version is a single integer. `0` is until I release a version
+  "1.0.0" of node-bunyan. Thereafter, starting with `1`, this will be
+  incremented if there is any backward incompatible change to the log record
+  format. Details will be in "CHANGES.md" (the change log).
+- `level`: Required. Integer. Added by Bunyan. Cannot be overridden.
+  See the "Levels" section.
+- `name`: Required. String. Provided at Logger creation.
+  You must specify a name for your logger when creating it. Typically this
+  is the name of the service/app using Bunyan for logging.
+- `hostname`: Required. String. Provided or determined at Logger creation.
+  You can specify your hostname at Logger creation or it will be retrieved
+  vi `os.hostname()`.
+- `pid`: Required. Integer. Filled in automatically at Logger creation.
+- `time`: Required. String. Added by Bunyan. Can be overridden.
+  The date and time of the event in [ISO 8601
+  Extended Format](http://en.wikipedia.org/wiki/ISO_8601) format and in UTC,
+  as from
+  [`Date.toISOString()`](https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/toISOString).
+- `msg`: Required. String.
+  Every `log.debug(...)` et al call must provide a log message.
+- `src`: Optional. Object giving log call source info. This is added
+  automatically by Bunyan if the "src: true" config option is given to the
+  Logger. Never use in production as this is really slow.
+
+
+Go ahead and add more fields, and nested ones are fine (and recommended) as
+well. This is why we're using JSON. Some suggestions and best practices
+follow (feedback from actual users welcome).
+
+
+## Recommended/Best Practice Fields
+
+- `err`: Object. A caught JS exception. Log that thing with `log.info(err)`
+    to get:
+
+    ```js
+    ...
+    "err": {
+      "message": "boom",
+      "name": "TypeError",
+      "stack": "TypeError: boom\n    at Object.<anonymous> ..."
+    },
+    "msg": "boom",
+    ...
+    ```
+
+    Or use the `bunyan.stdSerializers.err` serializer in your Logger and
+    do this `log.error({err: err}, "oops")`. See "examples/err.js".
+
+- `req_id`: String. A request identifier. Including this field in all logging
+  tied to handling a particular request to your server is strongly suggested.
+  This allows post analysis of logs to easily collate all related logging
+  for a request. This really shines when you have a SOA with multiple services
+  and you carry a single request ID from the top API down through all APIs
+  (as [node-restify](https://github.com/mcavage/node-restify) facilitates
+  with its 'Request-Id' header).
+
+- `req`: An HTTP server request. Bunyan provides `bunyan.stdSerializers.req`
+  to serialize a request with a suggested set of keys. Example:
+
+    ```js
+    {
+      "method": "GET",
+      "url": "/path?q=1#anchor",
+      "headers": {
+        "x-hi": "Mom",
+        "connection": "close"
+      },
+      "remoteAddress": "120.0.0.1",
+      "remotePort": 51244
+    }
+    ```
+
+- `res`: An HTTP server response. Bunyan provides `bunyan.stdSerializers.res`
+  to serialize a response with a suggested set of keys. Example:
+
+    ```js
+    {
+      "statusCode": 200,
+      "header": "HTTP/1.1 200 OK\r\nContent-Type: text/plain\r\nConnection: keep-alive\r\nTransfer-Encoding: chunked\r\n\r\n"
+    }
+    ```
+
+## Other fields to consider
+
+- `req.username`: Authenticated user (or for a 401, the user attempting to
+  auth).
+- Some mechanism to calculate response latency. "restify" users will have
+  a "X-Response-Time" header. A `latency` custom field would be fine.
+- `req.body`: If you know that request bodies are small (common in APIs,
+  for example), then logging the request body is good.
+

+A "stream" is Bunyan's name for where it outputs log messages (the equivalent
+to a log4j Appender). Ultimately Bunyan uses a
+[Writable Stream](https://nodejs.org/docs/latest/api/all.html#writable_Stream)
+interface, but there are some additional attributes used to create and
+manage the stream. A Bunyan Logger instance has one or more streams.
+In general streams are specified with the "streams" option:
+
+```js
+var bunyan = require('bunyan');
+var log = bunyan.createLogger({
+    name: "foo",
+    streams: [
+        {
+            stream: process.stderr,
+            level: "debug"
+        },
+        ...
+    ]
+});
+```
+
+For convenience, if there is only one stream, it can specified with the
+"stream" and "level" options (internally converted to a `Logger.streams`).
+
+```js
+var log = bunyan.createLogger({
+    name: "foo",
+    stream: process.stderr,
+    level: "debug"
+});
+```
+
+Note that "file" streams do not support this shortcut (partly for historical
+reasons and partly to not make it difficult to add a literal "path" field
+on log records).
+
+If neither "streams" nor "stream" are specified, the default is a stream of
+type "stream" emitting to `process.stdout` at the "info" level.
+
+## Adding a Stream
+
+After a bunyan instance has been initialized, you may add additional streams by
+calling the `addStream` function.
+
+```js
+var bunyan = require('bunyan');
+var log = bunyan.createLogger('myLogger');
+log.addStream({
+  name: "myNewStream",
+  stream: process.stderr,
+  level: "debug"
+});
+```
+
+## stream errors
+
+A Bunyan logger instance can be made to re-emit "error" events from its
+streams. Bunyan does so by default for [`type === "file"`
+streams](#stream-type-file), so you can do this:
+
+```js
+var log = bunyan.createLogger({name: 'mylog', streams: [{path: LOG_PATH}]});
+log.on('error', function (err, stream) {
+    // Handle stream write or create error here.
+});
+```
+
+As of bunyan@1.7.0, the `reemitErrorEvents` field can be used when adding a
+stream to control whether "error" events are re-emitted on the Logger. For
+example:
+
+    var EventEmitter = require('events').EventEmitter;
+    var util = require('util');
+
+    function MyFlakyStream() {}
+    util.inherits(MyFlakyStream, EventEmitter);
+
+    MyFlakyStream.prototype.write = function (rec) {
+        this.emit('error', new Error('boom'));
+    }
+
+    var log = bunyan.createLogger({
+        name: 'this-is-flaky',
+        streams: [
+            {
+                type: 'raw',
+                stream: new MyFlakyStream(),
+                reemitErrorEvents: true
+            }
+        ]
+    });
+    log.info('hi there');
+
+The behaviour is as follows:
+
+- `reemitErrorEvents` not specified: `file` streams will re-emit error events
+  on the Logger instance.
+- `reemitErrorEvents: true`: error events will be re-emitted on the Logger
+  for any stream with a `.on()` function -- which includes file streams,
+  process.stdout/stderr, and any object that inherits from EventEmitter.
+- `reemitErrorEvents: false`: error events will not be re-emitted for any
+  streams.
+
+Note: "error" events are **not** related to log records at the "error" level
+as produced by `log.error(...)`. See [the node.js docs on error
+events](https://nodejs.org/api/events.html#events_error_events) for details.
+
+
+## stream type: `stream`
+
+A `type === 'stream'` is a plain ol' node.js [Writable
+Stream](http://nodejs.org/docs/latest/api/all.html#writable_Stream). A
+"stream" (the writable stream) field is required. E.g.: `process.stdout`,
+`process.stderr`.
+
+```js
+var log = bunyan.createLogger({
+    name: 'foo',
+    streams: [{
+        stream: process.stderr
+        // `type: 'stream'` is implied
+    }]
+});
+```

+
+## stream type: `file`
+
+A `type === 'file'` stream requires a "path" field. Bunyan will open this
+file for appending. E.g.:
+
+```js
+var log = bunyan.createLogger({
+    name: 'foo',
+    streams: [{
+        path: '/var/log/foo.log',

+
+## stream type: `rotating-file`
+
+**WARNING on node 0.8 usage:** Users of Bunyan's `rotating-file` should (a) be
+using at least bunyan 0.23.1 (with the fix for [this
+issue](https://github.com/trentm/node-bunyan/pull/97)), and (b) should use at
+least node 0.10 (node 0.8 does not support the `unref()` method on
+`setTimeout(...)` needed for the mentioned fix). The symptom is that process
+termination will hang for up to a full rotation period.
+
+**WARNING on [cluster](http://nodejs.org/docs/latest/api/all.html#all_cluster)
+usage:** Using Bunyan's `rotating-file` stream with node.js's "cluster" module
+can result in unexpected file rotation. You must not have multiple processes
+in the cluster logging to the same file path. In other words, you must have
+a separate log file path for the master and each worker in the cluster.
+Alternatively, consider using a system file rotation facility such as
+`logrotate` on Linux or `logadm` on SmartOS/Illumos. See
+[this comment on issue #117](https://github.com/trentm/node-bunyan/issues/117#issuecomment-44804938)
+for details.
+
+A `type === 'rotating-file'` is a file stream that handles file automatic
+rotation.
+
+```js
+var log = bunyan.createLogger({
+    name: 'foo',
+    streams: [{
+        type: 'rotating-file',
+        path: '/var/log/foo.log',
+        period: '1d',   // daily rotation
+        count: 3        // keep 3 back copies
+    }]
+});
+```
+
+This will rotate '/var/log/foo.log' every day (at midnight) to:
+
+```sh
+/var/log/foo.log.0     # yesterday
+/var/log/foo.log.1     # 1 day ago
+/var/log/foo.log.2     # 2 days ago
+```
+
+*Currently*, there is no support for providing a template for the rotated
+files, or for rotating when the log reaches a threshold size.

+</table>
+
+
+**Note on log rotation**: Often you may be using external log rotation utilities
+like `logrotate` on Linux or `logadm` on SmartOS/Illumos. In those cases, unless
+your are ensuring "copy and truncate" semantics (via `copytruncate` with
+logrotate or `-c` with logadm) then the fd for your 'file' stream will change.
+You can tell bunyan to reopen the file stream with code like this in your
+app:
+
+```js
+var log = bunyan.createLogger(...);
+...
+process.on('SIGUSR2', function () {
+    log.reopenFileStreams();
+});
+```
+
+where you'd configure your log rotation to send SIGUSR2 (or some other signal)
+to your process. Any other mechanism to signal your app to run
+`log.reopenFileStreams()` would work as well.
+
+
+## stream type: `raw`
+
+- `raw`: Similar to a "stream" writable stream, except that the write method
+  is given raw log record *Object*s instead of a JSON-stringified string.
+  This can be useful for hooking on further processing to all Bunyan logging:
+  pushing to an external service, a RingBuffer (see below), etc.
+
+
+
+## `raw` + RingBuffer Stream
+
+Bunyan comes with a special stream called a RingBuffer which keeps the last N
+records in memory and does *not* write the data anywhere else.  One common
+strategy is to log 'info' and higher to a normal log file but log all records
+(including 'trace') to a ringbuffer that you can access via a debugger, or your
+own HTTP interface, or a post-mortem facility like MDB or node-panic.
+
+To use a RingBuffer:
+
+```js
+/* Create a ring buffer that stores the last 100 records. */
+var bunyan = require('bunyan');
+var ringbuffer = new bunyan.RingBuffer({ limit: 100 });
+var log = bunyan.createLogger({
+    name: 'foo',
+    streams: [
+        {
+            level: 'info',
+            stream: process.stdout
+        },
+        {
+            level: 'trace',
+            type: 'raw',    // use 'raw' to get raw log record objects
+            stream: ringbuffer
+        }
+    ]
+});
+
+log.info('hello world');
+console.log(ringbuffer.records);
+```
+
+This example emits:
+
+```js
+[ { name: 'foo',
+    hostname: '912d2b29',
+    pid: 50346,
+    level: 30,
+    msg: 'hello world',
+    time: '2012-06-19T21:34:19.906Z',
+    v: 0 } ]
+```
+
+## third-party streams
+
+See the [user-maintained list in the Bunyan
+wiki](https://github.com/trentm/node-bunyan/wiki/Awesome-Bunyan).
+
+
+# Runtime log snooping via DTrace
+
+On systems that support DTrace (e.g., illumos derivatives like SmartOS and
+OmniOS, FreeBSD, Mac), Bunyan will create a DTrace provider (`bunyan`) that
+makes available the following probes:
+
+```sh
+log-trace
+log-debug
+log-info
+log-warn
+log-error
+log-fatal
+```
+
+Each of these probes has a single argument: the string that would be
+written to the log.  Note that when a probe is enabled, it will
+fire whenever the corresponding function is called, even if the level of
+the log message is less than that of any stream.
+
+
+## DTrace examples
+
+Trace all log messages coming from any Bunyan module on the system.
+(The `-x strsize=4k` is to raise dtrace's default 256 byte buffer size
+because log messages are longer than typical dtrace probes.)
+
+```sh
+dtrace -x strsize=4k -qn 'bunyan*:::log-*{printf("%d: %s: %s", pid, probefunc, copyinstr(arg0))}'
+```
+
+Trace all log messages coming from the "wuzzle" component:
+
+```sh
+dtrace -x strsize=4k -qn 'bunyan*:::log-*/strstr(this->str = copyinstr(arg0), "\"component\":\"wuzzle\"") != NULL/{printf("%s", this->str)}'
+```
+
+Aggregate debug messages from process 1234, by message:
+
+```sh
+dtrace -x strsize=4k -n 'bunyan1234:::log-debug{@[copyinstr(arg0)] = count()}'
+```
+
+Have the bunyan CLI pretty-print the traced logs:
+
+```sh
+dtrace -x strsize=4k -qn 'bunyan1234:::log-*{printf("%s", copyinstr(arg0))}' | bunyan
+```
+
+A convenience handle has been made for this:
+
+```sh
+bunyan -p 1234
+```
+
+On systems that support the
+[`jstack`](http://dtrace.org/blogs/dap/2012/04/25/profiling-node-js/) action
+via a node.js helper, get a stack backtrace for any debug message that
+includes the string "danger!":
+
+```sh
+dtrace -x strsize=4k -qn 'log-debug/strstr(copyinstr(arg0), "danger!") != NULL/{printf("\n%s", copyinstr(arg0)); jstack()}'
+```
+
+Output of the above might be:
+
+```
+{"name":"foo","hostname":"763bf293-d65c-42d5-872b-4abe25d5c4c7.local","pid":12747,"level":20,"msg":"danger!","time":"2012-10-30T18:28:57.115Z","v":0}

+# Runtime environments
+
+Node-bunyan supports running in a few runtime environments:
+
+- [Node.js](https://nodejs.org/)
+- [Browserify](http://browserify.org/): See the
+  [Browserify section](#browserify) below.
+- [Webpack](https://webpack.github.io/): See the [Webpack section](#webpack) below.
+- [NW.js](http://nwjs.io/)
+
+Support for other runtime environments is welcome. If you have suggestions,
+fixes, or mentions that node-bunyan already works in some other JavaScript
+runtime, please open an [issue](https://github.com/trentm/node-bunyan/issues/new)
+or a pull request.
+
+The primary target is Node.js. It is the only environment in which I
+regularly test. If you have suggestions for how to automate testing for other
+environments, I'd appreciate feedback on [this automated testing
+issue](https://github.com/trentm/node-bunyan/issues/342).
+
+## Browserify
+
+As the [Browserify](http://browserify.org/) site says it "lets you
+`require('modules')` in the browser by bundling up all of your dependencies."
+It is a build tool to run on your node.js script to bundle up your script and
+all its node.js dependencies into a single file that is runnable in the
+browser via:
+
+```html
+<script src="play.browser.js"></script>
+```
+
+As of version 1.1.0, node-bunyan supports being run via Browserify. The
+default [stream](#streams) when running in the browser is one that emits
+raw log records to `console.log/info/warn/error`.
+
+Here is a quick example showing you how you can get this working for your
+script.
+
+1. Get browserify and bunyan installed in your module:
+
+    ```sh
+    $ npm install browserify bunyan
+    ```
+
+2. An example script using Bunyan, "play.js":
+
+    ```js
+    var bunyan = require('bunyan');
+    var log = bunyan.createLogger({name: 'play', level: 'debug'});
+    log.trace('this one does not emit');
+    log.debug('hi on debug');   // console.log
+    log.info('hi on info');     // console.info
+    log.warn('hi on warn');     // console.warn
+    log.error('hi on error');   // console.error
+    ```
+
+3. Build this into a bundle to run in the browser, "play.browser.js":
+
+    ```sh
+    $ ./node_modules/.bin/browserify play.js -o play.browser.js
+    ```
+
+4. Put that into an HTML file, "play.html":
+
+    ```html
+    <!DOCTYPE html>
+    <html>
+    <head>
+      <meta charset="utf-8">
+      <script src="play.browser.js"></script>
+    </head>
+    <body>
+      <div>hi</div>
+    </body>
+    </html>
+    ```
+
+5. Open that in your browser and open your browser console:
+
+    ```sh
+    $ open play.html
+    ```
+
+Here is what it looks like in Firefox's console: ![Bunyan + Browserify in the
+Firefox console](./docs/img/bunyan.browserify.png)
+
+For some, the raw log records might not be desired. To have a rendered log line
+you'll want to add your own stream, starting with something like this:
+
+```js
+var bunyan = require('./lib/bunyan');
+
+function MyRawStream() {}
+MyRawStream.prototype.write = function (rec) {
+    console.log('[%s] %s: %s',
+        rec.time.toISOString(),
+        bunyan.nameFromLevel[rec.level],
+        rec.msg);
+}
+
+var log = bunyan.createLogger({
+    name: 'play',
+    streams: [
+        {

+            stream: new MyRawStream(),
+            type: 'raw'
+        }
+    ]
+});
+
+log.info('hi on info');
+```
+
+## Webpack
+Webpack can work with the same example Browserify above. To do this, we need to make webpack ignore optional files:
+Create "empty_shim.js":
+```javascript
+// This is an empty shim for things that should be not be included in webpack
+```
+Now tell webpack to use this file for
+[optional dependencies](https://webpack.github.io/docs/configuration.html#resolve-alias)
+in your "webpack.config.js":
+```
+resolve: {
+    // These shims are needed for bunyan
+    alias: {
+        'dtrace-provider': '/path/to/shim/empty_shim.js',
+        fs: '/path/to/shim/empty_shim.js',
+        'safe-json-stringify': '/path/to/shim/empty_shim.js',
+        mv: '/path/to/shim/empty_shim.js',
+        'source-map-support': '/path/to/shim/empty_shim.js'
+    }
+}
+```
+Now webpack builds, ignoring these optional dependencies via shimming in an empty JS file!

+# higher prio
+
+- `bunyan` (without redir) ^C should stop, doesn't since recent change
+- man page for the bunyan CLI (refer to it in the readme)
+    - perhaps wait for a bunyan new version with deps, and use dashdash
+      with a (vapour) man page generator
+
+# v2
+
+- ^C fix
+- node-exeunt
+- `createLogger(<config-and-fields>, <fields>)` changes (#460)
+    - see section below
+- the dtrace-provider thing (#487)
+    TODO: answer Cody email
+- use package.json version for VERSION
+- use deps
+    - dashdash
+    - assert-plus?
+    - verror?
+- break out to multiple files
+    - want to work through PRs before that, so don't just break them all
+- TODO: a quick pass through tickets and pulls for other things to include
+- get ticket refs for the above, if any
+- formatters: read up again on `glp master..1.x`
+- support for customer formatters
+    - for the CLI as well? How? ~/.bunyanrc?
+
+
+# changes to ctor and log.child to separate fields from config
+
+<https://github.com/trentm/node-bunyan/issues/460>
+
+Current:
+
+    createLogger(<config-and-fields>)
+    log.child(<config-and-fields>, <just-fields-bool>)
+
+Could be:
+
+    createLogger(<config-and-fields>, <fields>)
+    log.child(<config-and-fields>, <fields>)
+        # Still support: log.child(<config-and-fields>, <just-fields-bool>)
+
+Pros: Compat issues are minimal: a change is only required if there is a
+collision with used field and a new config var name.
+Cons: A *slight* con is that my guess is the common usage of child is
+`log.child(<fields>)`, so the more future-proof common usage becomes:
+
+    log.child(null, <fields>)
+
+That's not too bad. It is clearer at least than:
+
+    log.child(<fields>, true)
+
+TODO:
+
+- is there a ticket for this work already?
+- make the change
+- do a migration guide? i.e. provide the grep commands to find all
+  possible calls to inspect. E.g. if don't have `rg logUndefined` in your
+  code, then you are fine. And one time future-proofing via changing
+  to fields in the *second* arg.
+- list of issues/pulls that wanted to add new config fields
+
+
+
+# docs
+
+- document log.addStream() and log.addSerializers()
+
+
+# someday/maybe
+
+- 2.0 (?) with `v: 1` in log records. Fwd/bwd compat in `bunyan` CLI
+- `tail -f`-like support
+- full-on docs
+- better examples/
+- better coloring
+- look at pino (bunyan style, perf benefits)
+- would be exciting to have bunyan support in http://lnav.org/ if that
+  made sense
+- "template" support for 'rotating-file' stream to get dated rolled files
+- "all" or "off" levels? log4j? logging.py?
+  logging.py has NOTSET === 0. I think that is only needed/used for
+  multi-level hierarchical effective level.
+- buffered writes to increase speed:
+    - I'd start with a tools/timeoutput.js for some numbers to compare
+      before/after. Sustained high output to a file.
+    - perhaps this would be a "buffered: true" option on the stream object
+    - then wrap the "stream" with a local class that handles the buffering
+    - to finish this, need the 'log.close' and `process.on('exit', ...)`
+      work that Trent has started.
+- "canWrite" handling for full streams. Need to buffer a la log4js
+- test file log with logadm rotation: does it handle that?
+- test suite:
+    - test for a cloned logger double-`stream.end()` causing problems.
+      Perhaps the "closeOnExit" for existing streams should be false for
+      clones.
+    - test that a `log.clone(...)` adding a new field matching a serializer
+      works *and* that an existing field in the parent is not *re-serialized*.
+- split out `bunyan` cli to a "bunyan" or "bunyan-reader" or "node-bunyan-reader"
+  as the basis for tools to consume bunyan logs. It can grow indep of node-bunyan
+  for generating the logs.
+  It would take a Bunyan log record object and be expected to emit it.
+
+        node-bunyan-reader
+            .createReadStream(path, [options]) ?
+
+- coloring bug: in less the indented extra info lines only have the first
+  line colored. Do we need the ANSI char on *each* line? That'll be
+  slower.
+- document "well-known" keys from bunyan CLI p.o.v.. Add "client_req".
+- More `bunyan` output formats and filtering features.
+- Think about a bunyan dashboard that supports organizing and viewing logs
+  from multiple hosts and services.
+- doc the restify RequestCaptureStream usage of RingBuffer. Great example.
+- A vim plugin (a la http://vim.cybermirror.org/runtime/autoload/zip.vim ?) to
+  allow browsing (read-only) a bunyan log in rendered form.
+- Some speed comparisons with others to get a feel for Bunyan's speed.
+- what about promoting 'latency' field and making that easier?
+- `log.close` to close streams and shutdown and `this.closed`
+  process.on('exit', log.close)
+  -> 'end' for the name
+- bunyan cli: more layouts (http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/EnhancedPatternLayout.html)
+  Custom log formats (in config file? in '-f' arg) using printf or hogan.js
+  or whatever. Dap wants field width control for lining up. Hogan.js is
+  probably overkill for this.
+- loggly example using raw streams, hook.io?, whatever.
+- serializer support:
+    - restify-server.js example -> restifyReq ? or have `req` detect that.
+      That is nicer for the "use all standard ones". *Does* restify req
+      have anything special?
+    - differential HTTP *client* req/res with *server* req/res.
+- statsd stream? http://codeascraft.etsy.com/2011/02/15/measure-anything-measure-everything/
+  Think about it.
+- web ui. Ideas: http://googlecloudplatform.blogspot.ca/2014/04/a-new-logs-viewer-for-google-cloud.html

+.
+.SH "NAME"
+\fBbunyan\fR \- filter and pretty\-print Bunyan log file content
+.
+.SH "SYNOPSIS"
+\fBbunyan\fR [OPTIONS]
+.
+.P
+\&\.\.\. | \fBbunyan\fR [OPTIONS]
+.
+.P
+\fBbunyan\fR [OPTIONS] \-p PID
+.
+.SH "DESCRIPTION"
+"Bunyan" is \fBa simple and fast a JSON logging library\fR for node\.js services, a one\-JSON\-object\-per\-line log format, and \fBa \fBbunyan\fR CLI tool\fR for nicely viewing those logs\. This man page describes the latter\.
+.
+.SS "Pretty\-printing"
+A bunyan log file is a stream of JSON objects, optionally interspersed with non\-JSON log lines\. The primary usage of bunyan(1) is to pretty print, for example:
+.
+.IP "" 4
+.
+.nf
+
+$ bunyan foo\.log          # or `cat foo\.log | bunyan
+[2012\-02\-08T22:56:52\.856Z]  INFO: myservice/123 on example\.com: My message
+    extra: multi
+    line
+[2012\-02\-08T22:56:54\.856Z] ERROR: myservice/123 on example\.com: My message
+\.\.\.
+.
+.fi
+.
+.IP "" 0
+.
+.P
+By default the "long" output format is used\. Use the \fB\-o FORMAT\fR option to emit other formats\. E\.g\.:
+.
+.IP "" 4
+.
+.nf
+
+$ bunyan foo\.log \-o short
+22:56:52\.856Z  INFO myservice: My message
+    extra: multi
+    line
+22:56:54\.856Z ERROR myservice: My message
+\.\.\.
+.
+.fi
+.
+.IP "" 0
+.
+.P
+These will color the output if supported in your terminal\. See "OUTPUT FORMATS" below\.
+.
+.SS "Filtering"
+The \fBbunyan\fR CLI can also be used to filter a bunyan log\. Use \fB\-l LEVEL\fR to filter by level:
+.
+.IP "" 4
+.
+.nf
+
+$ bunyan foo\.log \-l error       # show only \'error\' level records
+[2012\-02\-08T22:56:54\.856Z] ERROR: myservice/123 on example\.com: My message
+.
+.fi
+.
+.IP "" 0
+.
+.P
+Use \fB\-c COND\fR to filter on a JavaScript expression returning true on the record data\. In the COND code, \fBthis\fR refers to the record object:
+.
+.IP "" 4
+.
+.nf
+
+$ bunyan foo\.log \-c `this\.three`     # show records with the \'extra\' field
+[2012\-02\-08T22:56:52\.856Z]  INFO: myservice/123 on example\.com: My message
+    extra: multi
+    line
+.
+.fi
+.
+.IP "" 0
+.
+.SH "OPTIONS"
+.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Print this help info and exit\.
+.
+.TP
+\fB\-\-version\fR
+Print version of this command and exit\.
+.
+.TP
+\fB\-q\fR, \fB\-\-quiet\fR
+Don\'t warn if input isn\'t valid JSON\.
+.
+.P
+Dtrace options (only on dtrace\-supporting platforms):
+.
+.TP
+\fB\-p PID\fR, \fB\-p NAME\fR
+Process bunyan:log\-* probes from the process with the given PID\. Can be used multiple times, or specify all processes with \'*\', or a set of processes whose command & args match a pattern with \'\-p NAME\'\.
+.
+.P
+Filtering options:
+.
+.TP
+\fB\-l\fR, \fB\-\-level LEVEL\fR
+Only show messages at or above the specified level\. You can specify level \fInames\fR or numeric values\. (See \'Log Levels\' below\.)
+.
+.TP
+\fB\-c COND\fR, \fB\-\-condition COND\fR
+Run each log message through the condition and only show those that resolve to a truish value\. E\.g\. \fB\-c \'this\.pid == 123\'\fR\.
+.
+.TP
+\fB\-\-strict\fR
+Suppress all but legal Bunyan JSON log lines\. By default non\-JSON, and non\-Bunyan lines are passed through\.
+.
+.P
+Output options:
+.
+.TP
+\fB\-\-color\fR
+Colorize output\. Defaults to try if output stream is a TTY\.
+.
+.TP
+\fB\-\-no\-color\fR
+Force no coloring (e\.g\. terminal doesn\'t support it)
+.
+.TP
+\fB\-o FORMAT\fR, \fB\-\-output FORMAT\fR
+Specify an output format\. One of \fBlong\fR (the default), \fBshort\fR, \fBjson\fR, \fBjson\-N\fR, \fBbunyan\fR (the native bunyan 0\-indent JSON output) or \fBinspect\fR\.
+.
+.TP
+\fB\-j\fR
+Shortcut for \fB\-o json\fR\.
+.
+.TP
+\fB\-L\fR, \fB\-\-time local\fR
+Display the time field in \fIlocal\fR time, rather than the default UTC time\.
+.
+.SH "LOG LEVELS"
+In Bunyan log records, then \fBlevel\fR field is a number\. For the \fB\-l|\-\-level\fR argument the level \fBnames\fR are supported as shortcuts\. In \fB\-c|\-\-condition\fR scripts, uppercase symbols like "DEBUG" are defined for convenience\.
+.
+.IP "" 4
+.
+.nf
+
+Level Name      Level Number    Symbol in COND Scripts
+trace           10              TRACE

+.
+.IP "" 0
+.
+.SH "OUTPUT FORMATS"
+.
+.nf
+
+FORMAT NAME         DESCRIPTION
+long (default)      The default output\. Long form\. Colored and "pretty"\.
+                    \'req\' and \'res\' and \'err\' fields are rendered specially
+                    as an HTTP request, HTTP response and exception
+                    stack trace, respectively\. For backward compat, the
+                    name "paul" also works for this\.
+short               Like the default output, but more concise\. Some
+                    typically redundant fields are ellided\.
+json                JSON output, 2\-space indentation\.
+json\-N              JSON output, N\-space indentation, e\.g\. "json\-4"
+bunyan              Alias for "json\-0", the Bunyan "native" format\.
+inspect             Node\.js `util\.inspect` output\.
+.
+.fi
+.
+.SH "DTRACE SUPPORT"
+On systems that support DTrace (e\.g\., MacOS, FreeBSD, illumos derivatives like SmartOS and OmniOS), Bunyan will create a DTrace provider (\fBbunyan\fR) that makes available the following probes:
+.
+.IP "" 4
+.
+.nf
+
+log\-trace
+log\-debug
+log\-info
+log\-warn
+log\-error
+log\-fatal
+.
+.fi
+.
+.IP "" 0
+.
+.P
+Each of these probes has a single argument: the string that would be written to the log\. Note that when a probe is enabled, it will fire whenever the corresponding function is called, even if the level of the log message is less than that of any stream\.
+.
+.P
+See \fIhttps://github\.com/trentm/node\-bunyan#dtrace\-support\fR for more details and the \'\-p PID\' option above for convenience usage\.
+.
+.SH "ENVIRONMENT"
+.
+.TP
+\fBBUNYAN_NO_COLOR\fR
+Set to a non\-empty value to force no output coloring\. See \'\-\-no\-color\'\.
+.
+.SH "PROJECT & BUGS"
+\fBbunyan\fR is written in JavaScript and requires node\.js (\fBnode\fR)\. The project lives at \fIhttps://github\.com/trentm/node\-bunyan\fR and is published to npm as "bunyan"\.

+# bunyan(1) -- filter and pretty-print Bunyan log file content
+
+
+## SYNOPSIS
+
+`bunyan` \[OPTIONS\]
+
+... | `bunyan` \[OPTIONS\]
+
+`bunyan` \[OPTIONS\] -p PID
+
+
+## DESCRIPTION
+
+"Bunyan" is **a simple and fast a JSON logging library** for node.js services,
+a one-JSON-object-per-line log format, and **a `bunyan` CLI tool** for nicely
+viewing those logs. This man page describes the latter.
+
+
+### Pretty-printing
+
+A bunyan log file is a stream of JSON objects, optionally interspersed with
+non-JSON log lines. The primary usage of bunyan(1) is to pretty print,
+for example:
+
+    $ bunyan foo.log          # or `cat foo.log | bunyan
+    [2012-02-08T22:56:52.856Z]  INFO: myservice/123 on example.com: My message
+        extra: multi
+        line
+    [2012-02-08T22:56:54.856Z] ERROR: myservice/123 on example.com: My message
+    ...
+
+By default the "long" output format is used. Use the `-o FORMAT` option to
+emit other formats. E.g.:
+
+    $ bunyan foo.log -o short
+    22:56:52.856Z  INFO myservice: My message
+        extra: multi
+        line
+    22:56:54.856Z ERROR myservice: My message
+    ...
+
+These will color the output if supported in your terminal.
+See "OUTPUT FORMATS" below.
+
+
+### Filtering
+
+The `bunyan` CLI can also be used to filter a bunyan log. Use `-l LEVEL`
+to filter by level:
+
+    $ bunyan foo.log -l error       # show only 'error' level records
+    [2012-02-08T22:56:54.856Z] ERROR: myservice/123 on example.com: My message
+
+Use `-c COND` to filter on a JavaScript expression returning true on the
+record data. In the COND code, `this` refers to the record object:
+
+    $ bunyan foo.log -c `this.three`     # show records with the 'extra' field
+    [2012-02-08T22:56:52.856Z]  INFO: myservice/123 on example.com: My message
+        extra: multi
+        line
+
+
+## OPTIONS
+
+  * `-h`, `--help`:
+    Print this help info and exit.
+
+  * `--version`:
+    Print version of this command and exit.
+
+  * `-q`, `--quiet`:
+    Don't warn if input isn't valid JSON.
+
+Dtrace options (only on dtrace-supporting platforms):
+
+  * `-p PID`, `-p NAME`:
+    Process bunyan:log-\* probes from the process with the given PID.
+    Can be used multiple times, or specify all processes with '\*',
+    or a set of processes whose command & args match a pattern with
+    '-p NAME'.
+
+Filtering options:
+
+  * `-l`, `--level LEVEL`:
+    Only show messages at or above the specified level. You can specify level
+    *names* or numeric values. (See 'Log Levels' below.)
+
+  * `-c COND`, `--condition COND`:
+    Run each log message through the condition and only show those that
+    resolve to a truish value. E.g. `-c 'this.pid == 123'`.
+
+  * `--strict`:
+    Suppress all but legal Bunyan JSON log lines. By default non-JSON, and
+    non-Bunyan lines are passed through.
+
+Output options:
+
+  * `--color`:
+    Colorize output. Defaults to try if output stream is a TTY.
+
+  * `--no-color`:
+    Force no coloring (e.g. terminal doesn't support it)
+
+  * `-o FORMAT`, `--output FORMAT`:
+    Specify an output format. One of `long` (the default), `short`, `json`,
+    `json-N`, `bunyan` (the native bunyan 0-indent JSON output) or `inspect`.
+
+  * `-j`:
+    Shortcut for `-o json`.
+
+  * `-L`, `--time local`:
+    Display the time field in *local* time, rather than the default UTC
+    time.
+
+
+## LOG LEVELS
+
+In Bunyan log records, then `level` field is a number. For the `-l|--level`
+argument the level **names** are supported as shortcuts. In `-c|--condition`
+scripts, uppercase symbols like "DEBUG" are defined for convenience.
+
+    Level Name      Level Number    Symbol in COND Scripts
+    trace           10              TRACE
+    debug           20              DEBUG
+    info            30              INFO
+    warn            40              WARN
+    error           50              ERROR
+    fatal           60              FATAL
+
+
+## OUTPUT FORMATS
+
+    FORMAT NAME         DESCRIPTION
+    long (default)      The default output. Long form. Colored and "pretty".
+                        'req' and 'res' and 'err' fields are rendered specially
+                        as an HTTP request, HTTP response and exception
+                        stack trace, respectively. For backward compat, the
+                        name "paul" also works for this.
+    short               Like the default output, but more concise. Some
+                        typically redundant fields are ellided.
+    json                JSON output, 2-space indentation.
+    json-N              JSON output, N-space indentation, e.g. "json-4"
+    bunyan              Alias for "json-0", the Bunyan "native" format.
+    inspect             Node.js `util.inspect` output.
+
+
+## DTRACE SUPPORT
+
+On systems that support DTrace (e.g., MacOS, FreeBSD, illumos derivatives
+like SmartOS and OmniOS), Bunyan will create a DTrace provider (`bunyan`)
+that makes available the following probes:
+
+    log-trace
+    log-debug
+    log-info
+    log-warn
+    log-error
+    log-fatal
+
+Each of these probes has a single argument: the string that would be
+written to the log.  Note that when a probe is enabled, it will
+fire whenever the corresponding function is called, even if the level of
+the log message is less than that of any stream.
+
+See <https://github.com/trentm/node-bunyan#dtrace-support> for more details
+and the '-p PID' option above for convenience usage.
+
+
+## ENVIRONMENT
+
+  * `BUNYAN_NO_COLOR`:
+    Set to a non-empty value to force no output coloring. See '--no-color'.
+
+

+ * - node.js: The primary target environment.
+ * - NW.js: http://nwjs.io/  An *app* environment that feels like both a
+ *   node env -- it has node-like globals (`process`, `global`) and
+ *   browser-like globals (`window`, `navigator`). My *understanding* is that
+ *   bunyan can operate as if this is vanilla node.js.
+ * - browser: Failing the above, we sniff using the `window` global
+ *   <https://developer.mozilla.org/en-US/docs/Web/API/Window/window>.
+ *      - browserify: http://browserify.org/  A browser-targetting bundler of
+ *        node.js deps. The runtime is a browser env, so can't use fs access,
+ *        etc. Browserify's build looks for `require(<single-string>)` imports
+ *        to bundle. For some imports it won't be able to handle, we "hide"
+ *        from browserify with `require('frobshizzle' + '')`.
+ * - Other? Please open issues if things are broken.

+# Emitter [![Build Status](https://travis-ci.org/component/emitter.png)](https://travis-ci.org/component/emitter)
+
+  Event emitter component.
+
+## Installation
+
+```
+$ component install component/emitter
+```
+
+## API
+
+### Emitter(obj)
+
+  The `Emitter` may also be used as a mixin. For example
+  a "plain" object may become an emitter, or you may
+  extend an existing prototype.
+
+  As an `Emitter` instance:
+
+```js
+var Emitter = require('emitter');
+var emitter = new Emitter;
+emitter.emit('something');
+```
+
+  As a mixin:
+
+```js
+var Emitter = require('emitter');
+var user = { name: 'tobi' };
+Emitter(user);
+
+user.emit('im a user');
+```
+
+  As a prototype mixin:
+
+```js
+var Emitter = require('emitter');
+Emitter(User.prototype);
+```
+
+### Emitter#on(event, fn)
+
+  Register an `event` handler `fn`.
+
+### Emitter#once(event, fn)
+
+  Register a single-shot `event` handler `fn`,
+  removed immediately after it is invoked the
+  first time.
+
+### Emitter#off(event, fn)
+
+  * Pass `event` and `fn` to remove a listener.
+  * Pass `event` to remove all listeners on that event.
+  * Pass nothing to remove all listeners on all events.
+
+### Emitter#emit(event, ...)
+
+  Emit an `event` with variable option args.
+
+### Emitter#listeners(event)
+
+  Return an array of callbacks, or an empty array.
+
+### Emitter#hasListeners(event)
+
+  Check if this emitter has `event` handlers.

+concatMap(xs, fn)
+-----------------
+
+Return an array of concatenated elements by calling `fn(x, i)` for each element
+`x` and each index `i` in the array `xs`.
+
+When `fn(x, i)` returns an array, its result will be concatenated with the
+result array. If `fn(x, i)` returns anything else, that value will be pushed
+onto the end of the result array.

+
+Basic HTTP cookie parser and serializer for HTTP servers.
+
+## Installation
+
+```sh
+$ npm install cookie
+```
+
+## API
+
+```js
+var cookie = require('cookie');
+```
+
+### cookie.parse(str, options)
+
+Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs.
+The `str` argument is the string representing a `Cookie` header value and `options` is an
+optional object containing additional parsing options.
+
+```js
+var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2');
+// { foo: 'bar', equation: 'E=mc^2' }
+```
+
+#### Options
+
+`cookie.parse` accepts these properties in the options object.
+
+##### decode
+
+Specifies a function that will be used to decode a cookie's value. Since the value of a cookie
+has a limited character set (and must be a simple string), this function can be used to decode
+a previously-encoded cookie value into a JavaScript string or other object.
+
+The default function is the global `decodeURIComponent`, which will decode any URL-encoded
+sequences into their byte representations.
+
+**note** if an error is thrown from this function, the original, non-decoded cookie value will
+be returned as the cookie's value.
+
+### cookie.serialize(name, value, options)
+
+Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the
+name for the cookie, the `value` argument is the value to set the cookie to, and the `options`
+argument is an optional object containing additional serialization options.
+
+```js
+var setCookie = cookie.serialize('foo', 'bar');
+// foo=bar
+```
+
+#### Options
+
+`cookie.serialize` accepts these properties in the options object.
+
+##### domain
+
+Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6266-5.2.3]. By default, no
+domain is set, and most clients will consider the cookie to apply to only the current domain.
+
+##### encode
+
+Specifies a function that will be used to encode a cookie's value. Since value of a cookie
+has a limited character set (and must be a simple string), this function can be used to encode
+a value into a string suited for a cookie's value.
+
+The default function is the global `ecodeURIComponent`, which will encode a JavaScript string
+into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range.
+
+##### expires
+
+Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6266-5.2.1].
+By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and
+will delete it on a condition like exiting a web browser application.
+
+**note** the [cookie storage model specification][rfc-6266-5.3] states that if both `expires` and
+`magAge` are set, then `maxAge` takes precedence, but it is possiblke not all clients by obey this,
+so if both are set, they should point to the same date and time.
+
+##### httpOnly
+
+Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6266-5.2.6]. When truthy,
+the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set.
+
+**note** be careful when setting this to `true`, as compliant clients will not allow client-side
+JavaScript to see the cookie in `document.cookie`.
+
+##### maxAge
+
+Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6266-5.2.2].
+The given number will be converted to an integer by rounding down. By default, no maximum age is set.
+
+**note** the [cookie storage model specification][rfc-6266-5.3] states that if both `expires` and
+`magAge` are set, then `maxAge` takes precedence, but it is possiblke not all clients by obey this,
+so if both are set, they should point to the same date and time.
+
+##### path
+
+Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6266-5.2.4]. By default, the path
+is considered the ["default path"][rfc-6266-5.1.4]. By default, no maximum age is set, and most
+clients will consider this a "non-persistent cookie" and will delete it on a condition like exiting
+a web browser application.
+
+##### sameSite
+
+Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][draft-west-first-party-cookies-07].
+
+  - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+  - `false` will not set the `SameSite` attribute.
+  - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement.
+  - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+
+More information about the different enforcement levels can be found in the specification
+https://tools.ietf.org/html/draft-west-first-party-cookies-07#section-4.1.1
+
+**note** This is an attribute that has not yet been fully standardized, and may change in the future.
+This also means many clients may ignore this attribute until they understand it.
+
+##### secure
+
+Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6266-5.2.5]. When truthy,
+the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set.
+
+**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to
+the server in the future if the browser does not have an HTTPS connection.
+
+## Example
+
+The following example uses this module in conjunction with the Node.js core HTTP server
+to prompt a user for their name and display it back on future visits.
+
+```js
+var cookie = require('cookie');
+var escapeHtml = require('escape-html');
+var http = require('http');
+var url = require('url');
+
+function onRequest(req, res) {
+  // Parse the query string
+  var query = url.parse(req.url, true, true).query;
+
+  if (query && query.name) {
+    // Set a new cookie with the name
+    res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), {
+      httpOnly: true,
+      maxAge: 60 * 60 * 24 * 7 // 1 week
+    }));
+
+    // Redirect back after setting cookie
+    res.statusCode = 302;
+    res.setHeader('Location', req.headers.referer || '/');
+    res.end();
+    return;
+  }
+
+  // Parse the cookies on the request
+  var cookies = cookie.parse(req.headers.cookie || '');
+
+  // Get the visitor name set in the cookie
+  var name = cookies.name;
+
+  res.setHeader('Content-Type', 'text/html; charset=UTF-8');
+
+  if (name) {

+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+  , b = require('debug')('worker:b');
+
+function work() {
+  a('doing lots of uninteresting work');
+  setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+  b('doing some work');
+  setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
+
+#### Windows note
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Note that PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Then, run the program to be debugged as usual.
+
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".  If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable.  You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name      | Purpose                                         |
+|-----------|-------------------------------------------------|
+| `DEBUG`   | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY).  |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth.                    |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O`      | Pretty-print an Object on multiple lines. |
+| `%o`      | Pretty-print an Object all on a single line. |
+| `%s`      | String. |
+| `%d`      | Number (both integer and float). |
+| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%`      | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+  return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+  // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

+# dtrace-provider - Native DTrace providers for Node.js apps.
+
+This extension allows you to create native DTrace providers for your
+Node.js applications. That is, to create providers and probes which
+expose information specific to your application, rather than
+information about the node runtime.
+
+You could use this to expose high-level information about the inner
+workings of your application, or to create a specific context in which
+to look at information from other runtime or system-level providers. 
+
+The provider is not created in the usual way, by declaring it and then
+changing the build process to include it, but instead dynamically at
+runtime. This is done entirely in-process, and there is no background
+compiler or [dtrace(1M)](https://illumos.org/man/1M/dtrace) invocation.
+The process creating the provider need not run as root.
+
+## INSTALL
+
+    $ npm install dtrace-provider
+
+## EXAMPLE
+
+Here's a simple example of creating a provider:
+
+```javascript
+var d = require('dtrace-provider');
+
+var dtp = d.createDTraceProvider("nodeapp");
+var p1 = dtp.addProbe("probe1", "int", "int");
+var p2 = dtp.addProbe("probe2", "char *");
+dtp.enable();
+```
+
+Probes may be fired via the provider object:
+
+```javascript
+dtp.fire("probe1", function() {
+    return [1, 2];
+});
+dtp.fire("probe2", function() {
+    return ["hello, dtrace via provider", "foo"];
+});
+```
+
+or via the probe objects themselves:
+
+```javascript
+p1.fire(function() {
+  return [1, 2, 3, 4, 5, 6];
+});
+p2.fire(function() {
+  return ["hello, dtrace via probe", "foo"];
+});
+```
+
+Note that `.fire()` takes a callback that returns the arguments to be
+provided when the DTrace probe actually fires. This allows you to call
+`.fire()` unconditionally when you want to fire the probe, but the
+callback will be invoked only when the DTrace probe is actually
+enabled. This allows you to create probes whose arguments might be
+expensive to construct, and only do any work when the probe is
+actually enabled. (Examples might include converting a large object to
+a string representation or gathering large amounts of information.)
+
+In some cases, creating a new closure to pass to `.fire()` each time
+it's called may introduce unwanted overhead. For extremely
+CPU-intensive or memory-conscious workloads, you can avoid this by
+lifting the closures for your hot probes into an outer scope. You can
+then supply arguments to that function as additional arguments to
+`.fire()`. As an example, you can convert the following program:
+
+```javascript
+function manipulateObj(largeObj) {
+    var count = 0;
+    var name = null;
+    ...
+    p1.fire(function () {
+        return [count, keyToValue(name), JSON.stringify(largeObj)];
+    });
+}
+```
+
+Into this one:
+
+```javascript
+function f(a, b, c) {
+    return [a, keyToValue(b), JSON.stringify(c)];
+}
+
+function manipulateObj(largeObj) {
+    var count = 0;
+    var name = null;
+    ...
+    p1.fire(f, count, name, largeObj);
+}
+```
+
+Be careful to avoid passing `.fire()` additional arguments that are
+themselves expensive to construct, as that undermines the design goal
+here: minimizing the effect of disabled probes.
+
+This example creates a provider called "nodeapp", and adds two
+probes. It then enables the provider, at which point the provider
+becomes visible to DTrace.
+
+The probes are then fired, which produces this output:
+
+    $ sudo dtrace -Z -n 'nodeapp*:::probe1{ trace(arg0); trace(arg1) }'  \
+                     -n 'nodeapp*:::probe2{ trace(copyinstr(arg0));  }'
+    dtrace: description 'nodeapp*:::probe1' matched 0 probes
+    dtrace: description 'nodeapp*:::probe2' matched 0 probes
+    CPU     ID                    FUNCTION:NAME
+      1 123562                      func:probe1                 1                2
+      1 123563                      func:probe2   hello, dtrace                    
+
+Arguments are captured by a callback only executed when the probe is
+enabled. This means you can do more expensive work to gather arguments.
+
+The maximum number of arguments supported is 32. 
+
+Available argument types are "int", for integer numeric values,
+"char *" for strings, and "json" for objects rendered into JSON strings.
+
+Arguments typed as "json" will be created as "char *" probes in
+DTrace, but objects passed to these probe arguments will be
+automatically serialized to JSON before being passed to DTrace. This
+feature is best used in conjunction with the json() D subroutine, but
+is available whether or not the platform supports it.
+
+    # create a json probe:
+
+    var dtp = d.createDTraceProvider("nodeapp");
+    var p1 = dtp.addProbe("j1", "json");
+    dtp.enable();
+    p1.fire(function() { return { "foo": "bar" }; });
+
+    # on a platform supporting json():
+
+    $ sudo dtrace -Z -n 'nodeapp*:::j1{ this->j = copyinstr(arg0); \
+                                        trace(json(this->j, "foo")) }'
+    dtrace: description 'nodeapp$target:::j1' matched 0 probes
+    CPU     ID                    FUNCTION:NAME
+      0  68712                            j1:j1   bar
+
+## PLATFORM SUPPORT
+
+This libusdt-based Node.JS module supports 64 and 32 bit processes on
+Mac OS X and Solaris-like systems such as illumos or SmartOS. As more
+platform support is added to libusdt, those platforms will be
+supported by this module. See libusdt's status at:
+
+  https://github.com/chrisa/libusdt#readme
+
+When using Mac OS X, be aware that as of 10.11 (El Capitan), DTrace use
+is restricted, and you'll probably want to
+[disable SIP](http://internals.exposed/blog/dtrace-vs-sip.html) to
+effectively use DTrace.
+
+FreeBSD 10 and 11 are also supported, but you'll need to make sure that
+you have the DTrace headers installed in `/usr/src` otherwise libusdt
+won't be able to compile. You can
+[clone them using SVN](https://www.freebsd.org/doc/handbook/svn.html),
+or find the correct `src.txz`
+[here](http://ftp.freebsd.org/pub/FreeBSD/releases/) and extract that.
+Also note that FreeBSD 10 is restricted to only 4 working arguments per
+probe.
+
+Platforms not supporting DTrace (notably, Linux and Windows) may
+install this module without building libusdt, with a stub no-op
+implementation provided for compatibility. This allows cross-platform
+npm modules to embed probes and include a dependency on this module.
+
+GNU Make is required to build libusdt; the build scripts will look for
+gmake in `PATH` first, and then for make.
+
+### TROUBLESHOOTING BUILD ISSUES
+
+If compilation fails during installation on platforms with DTrace, then
+the library will fall back to the stub implementation that does nothing.
+To force an installation failure when compiling fails, set the environment
+variable `NODE_DTRACE_PROVIDER_REQUIRE` to `hard`:
+
+```shell
+$ NODE_DTRACE_PROVIDER_REQUIRE=hard npm install
+```
+
+This will then show you the output of the build process so you can see at
+which point it's having an issue. Common issues are:
+
+- Missing a C/C++ compiler toolchain for your platform.
+- `python` is Python 3 instead of Python 2; run `npm config set python python2.7`
+  (or similar) to set the Python binary npm uses.
+- On OS X you may need to agree to the XCode license if that's the compiler
+  toolchain you're using. This will usually manifest with an error like
+  `Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo.`
+  To accept the license, you can run `sudo xcodebuild -license`.
+
+Once you've found and fixed the issue, you can run `npm rebuild` to rerun
+the lifecycle scripts.
+
+## CAVEATS
+
+There is some overhead to probes, even when disabled. Probes are
+already using the "is-enabled" feature of DTrace to control execution
+of the arguments-gathering callback, but some work still needs to be
+done before that's checked. This overhead should not be a problem
+unless probes are placed in particularly hot code paths.

+## RUNNING THE TESTS
+
+```shell
+$ npm install
+$ sudo ./node_modules/.bin/tap --tap test/*.test.js
+```
+
+## OTHER IMPLEMENTATIONS
+
+This node extension is derived from the ruby-dtrace gem, via the Perl
+module Devel::DTrace::Provider, both of which provide the same
+functionality to those languages.

+libusdt
+=======
+
+This is "libusdt", a library for creating DTrace USDT providers.
+
+The idea here is to allow the specification of a DTrace provider
+dynamically in code and then create the provider at runtime. This
+allows providers to be specified in dynamic languages, given suitable
+bindings.
+
+The general approach is to create two stub functions for each probe,
+one for the is-enabled check and one for the probe itself. These
+contain the appropriate instruction sequences to appear to DTrace as
+compiled-in tracepoints. A minimal DOF document is built describing
+the provider and indicating these stub functions as the tracepoints,
+then submitted to the kernel, creating the provider. The API then
+exposes the stubs, through which the probes may be fired.
+
+Status
+------
+
+The implementation here works as shown in test_usdt.c on Mac OS X,
+i386 and x86_64, on Solaris-like systems, i386 and x86_64 and on
+FreeBSD and Oracle Linux, x86_64 only.
+
+Is-enabled probes are supported and exposed in the API.
+
+There is a "test" target which runs a number of tests of the library,
+for which perl is required.
+
+OS X builds are Universal by default, and on Solaris, the ARCH
+variable may be set to either i386 or x86_64 to force a particular
+build.
+
+FreeBSD builds suffer from broken argument handling; this is a known
+issue with the current state of DTrace generally on FreeBSD: only the
+first five arguments work reliably. See:
+
+  http://wiki.freebsd.org/DTraceTODO
+
+See Also
+--------
+
+There are various language bindings available:
+
+Lua:
+
+  https://github.com/chrisa/lua-usdt
+
+Ruby (by Kevin Chan):
+
+  https://github.com/kevinykchan/ruby-usdt
+
+Node.JS:
+
+  https://github.com/chrisa/node-dtrace-provider
+
+Perl:
+
+  https://github.com/chrisa/perl-Devel-DTrace-Provider
+
+To Do
+-----
+
+Platform support:
+
+ * add support for FreeBSD 9.0 i386
+ * add support for Mac OS X PowerPC
+ * add support for Solaris SPARC
+
+Features:
+
+ * add a "low level" API, allowing alternative provision of
+   tracepoints for closer integration with language VMs. 
+
+ * support structured types, with close integration with the host
+   DTrace system.

+# Engine.IO client
+
+[![Build Status](https://travis-ci.org/socketio/engine.io-client.svg?branch=master)](http://travis-ci.org/socketio/engine.io-client)
+[![NPM version](https://badge.fury.io/js/engine.io-client.svg)](http://badge.fury.io/js/engine.io-client)
+
+This is the client for [Engine.IO](http://github.com/socketio/engine.io),
+the implementation of transport-based cross-browser/cross-device
+bi-directional communication layer for [Socket.IO](http://github.com/socketio/socket.io).
+
+## How to use
+
+### Standalone
+
+You can find an `engine.io.js` file in this repository, which is a
+standalone build you can use as follows:
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+  // eio = Socket
+  var socket = eio('ws://localhost');
+  socket.on('open', function(){
+    socket.on('message', function(data){});
+    socket.on('close', function(){});
+  });
+</script>
+```
+
+### With browserify
+
+Engine.IO is a commonjs module, which means you can include it by using
+`require` on the browser and package using [browserify](http://browserify.org/):
+
+1. install the client package
+
+    ```bash
+    $ npm install engine.io-client
+    ```
+
+1. write your app code
+
+    ```js
+    var socket = require('engine.io-client')('ws://localhost');
+    socket.on('open', function(){
+      socket.on('message', function(data){});
+      socket.on('close', function(){});
+    });
+    ```
+
+1. build your app bundle
+
+    ```bash
+    $ browserify app.js > bundle.js
+    ```
+
+1. include on your page
+
+    ```html
+    <script src="/path/to/bundle.js"></script>
+    ```
+
+### Sending and receiving binary
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+  var socket = new eio.Socket('ws://localhost/');
+  socket.binaryType = 'blob';
+  socket.on('open', function () {
+    socket.send(new Int8Array(5));
+    socket.on('message', function(blob){});
+    socket.on('close', function(){ });
+  });
+</script>
+```
+
+### Node.JS
+
+Add `engine.io-client` to your `package.json` and then:
+
+```js
+var socket = require('engine.io-client')('ws://localhost');
+socket.on('open', function(){
+  socket.on('message', function(data){});
+  socket.on('close', function(){});
+});
+```
+
+### Node.js with certificates
+```js
+var opts = {
+  key: fs.readFileSync('test/fixtures/client.key'),
+  cert: fs.readFileSync('test/fixtures/client.crt'),
+  ca: fs.readFileSync('test/fixtures/ca.crt')
+};
+
+var socket = require('engine.io-client')('ws://localhost', opts);
+socket.on('open', function(){
+  socket.on('message', function(data){});
+  socket.on('close', function(){});
+});
+```
+
+### Node.js with extraHeaders
+```js
+var opts = {
+  extraHeaders: {
+    'X-Custom-Header-For-My-Project': 'my-secret-access-token',
+    'Cookie': 'user_session=NI2JlCKF90aE0sJZD9ZzujtdsUqNYSBYxzlTsvdSUe35ZzdtVRGqYFr0kdGxbfc5gUOkR9RGp20GVKza; path=/; expires=Tue, 07-Apr-2015 18:18:08 GMT; secure; HttpOnly'
+  }
+};
+
+var socket = require('engine.io-client')('ws://localhost', opts);
+socket.on('open', function(){
+  socket.on('message', function(data){});
+  socket.on('close', function(){});
+});
+```
+
+## Features
+
+- Lightweight
+- Runs on browser and node.js seamlessly
+- Transports are independent of `Engine`
+  - Easy to debug
+  - Easy to unit test
+- Runs inside HTML5 WebWorker
+- Can send and receive binary data
+  - Receives as ArrayBuffer or Blob when in browser, and Buffer or ArrayBuffer
+    in Node
+  - When XHR2 or WebSockets are used, binary is emitted directly. Otherwise
+    binary is encoded into base64 strings, and decoded when binary types are
+    supported.
+  - With browsers that don't support ArrayBuffer, an object { base64: true,
+    data: dataAsBase64String } is emitted on the `message` event.
+
+## API
+
+### Socket
+
+The client class. Mixes in [Emitter](http://github.com/component/emitter).
+Exposed as `eio` in the browser standalone build.
+
+#### Properties
+
+- `protocol` _(Number)_: protocol revision number
+- `binaryType` _(String)_ : can be set to 'arraybuffer' or 'blob' in browsers,
+  and `buffer` or `arraybuffer` in Node. Blob is only used in browser if it's
+  supported.
+
+#### Events
+
+- `open`
+  - Fired upon successful connection.
+- `message`
+  - Fired when data is received from the server.
+  - **Arguments**
+    - `String` | `ArrayBuffer`: utf-8 encoded data or ArrayBuffer containing
+      binary data
+- `close`
+  - Fired upon disconnection. In compliance with the WebSocket API spec, this event may be
+    fired even if the `open` event does not occur (i.e. due to connection error or `close()`).
+- `error`
+  - Fired when an error occurs.
+- `flush`
+  - Fired upon completing a buffer flush
+- `drain`
+  - Fired after `drain` event of transport if writeBuffer is empty
+- `upgradeError`
+  - Fired if an error occurs with a transport we're trying to upgrade to.
+- `upgrade`
+  - Fired upon upgrade success, after the new transport is set
+- `ping`
+  - Fired upon _flushing_ a ping packet (ie: actual packet write out)
+- `pong`
+  - Fired upon receiving a pong packet.
+
+#### Methods
+
+- **constructor**
+    - Initializes the client
+    - **Parameters**
+      - `String` uri
+      - `Object`: optional, options object
+    - **Options**
+      - `agent` (`http.Agent`): `http.Agent` to use, defaults to `false` (NodeJS only)
+      - `upgrade` (`Boolean`): defaults to true, whether the client should try
+      to upgrade the transport from long-polling to something better.
+      - `forceJSONP` (`Boolean`): forces JSONP for polling transport.
+      - `jsonp` (`Boolean`): determines whether to use JSONP when
+        necessary for polling. If disabled (by settings to false) an error will
+        be emitted (saying "No transports available") if no other transports
+        are available. If another transport is available for opening a
+        connection (e.g. WebSocket) that transport
+        will be used instead.
+      - `forceBase64` (`Boolean`): forces base 64 encoding for polling transport even when XHR2 responseType is available and WebSocket even if the used standard supports binary.
+      - `enablesXDR` (`Boolean`): enables XDomainRequest for IE8 to avoid loading bar flashing with click sound. default to `false` because XDomainRequest has a flaw of not sending cookie.
+      - `timestampRequests` (`Boolean`): whether to add the timestamp with each
+        transport request. Note: polling requests are always stamped unless this
+        option is explicitly set to `false` (`false`)
+      - `timestampParam` (`String`): timestamp parameter (`t`)
+      - `policyPort` (`Number`): port the policy server listens on (`843`)
+      - `path` (`String`): path to connect to, default is `/engine.io`
+      - `transports` (`Array`): a list of transports to try (in order).
+      Defaults to `['polling', 'websocket']`. `Engine`
+      always attempts to connect directly with the first one, provided the
+      feature detection test for it passes.
+      - `transportOptions` (`Object`): hash of options, indexed by transport name, overriding the common options for the given transport
+      - `rememberUpgrade` (`Boolean`): defaults to false.
+        If true and if the previous websocket connection to the server succeeded,
+        the connection attempt will bypass the normal upgrade process and will initially
+        try websocket. A connection attempt following a transport error will use the
+        normal upgrade process. It is recommended you turn this on only when using
+        SSL/TLS connections, or if you know that your network does not block websockets.
+      - `pfx` (`String`): Certificate, Private key and CA certificates to use for SSL. Can be used in Node.js client environment to manually specify certificate information.
+      - `key` (`String`): Private key to use for SSL. Can be used in Node.js client environment to manually specify certificate information.
+      - `passphrase` (`String`): A string of passphrase for the private key or pfx. Can be used in Node.js client environment to manually specify certificate information.
+      - `cert` (`String`): Public x509 certificate to use. Can be used in Node.js client environment to manually specify certificate information.
+      - `ca` (`String`|`Array`): An authority certificate or array of authority certificates to check the remote host against.. Can be used in Node.js client environment to manually specify certificate information.
+      - `ciphers` (`String`): A string describing the ciphers to use or exclude. Consult the [cipher format list](http://www.openssl.org/docs/apps/ciphers.html#CIPHER_LIST_FORMAT) for details on the format. Can be used in Node.js client environment to manually specify certificate information.
+      - `rejectUnauthorized` (`Boolean`): If true, the server certificate is verified against the list of supplied CAs. An 'error' event is emitted if verification fails. Verification happens at the connection level, before the HTTP request is sent. Can be used in Node.js client environment to manually specify certificate information.
+      - `perMessageDeflate` (`Object|Boolean`): parameters of the WebSocket permessage-deflate extension
+        (see [ws module](https://github.com/einaros/ws) api docs). Set to `false` to disable. (`true`)
+        - `threshold` (`Number`): data is compressed only if the byte size is above this value. This option is ignored on the browser. (`1024`)
+      - `extraHeaders` (`Object`): Headers that will be passed for each request to the server (via xhr-polling and via websockets). These values then can be used during handshake or for special proxies. Can only be used in Node.js client environment.
+      - `onlyBinaryUpgrades` (`Boolean`): whether transport upgrades should be restricted to transports supporting binary data (`false`)
+      - `forceNode` (`Boolean`): Uses NodeJS implementation for websockets - even if there is a native Browser-Websocket available, which is preferred by default over the NodeJS implementation. (This is useful when using hybrid platforms like nw.js or electron) (`false`, NodeJS only)
+      - `localAddress` (`String`): the local IP address to connect to
+    - **Polling-only options**
+      - `requestTimeout` (`Number`): Timeout for xhr-polling requests in milliseconds (`0`)
+    - **Websocket-only options**
+      - `protocols` (`Array`): a list of subprotocols (see [MDN reference](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#Subprotocols))
+- `send`
+    - Sends a message to the server
+    - **Parameters**
+      - `String` | `ArrayBuffer` | `ArrayBufferView` | `Blob`: data to send
+      - `Object`: optional, options object
+      - `Function`: optional, callback upon `drain`
+    - **Options**
+      - `compress` (`Boolean`): whether to compress sending data. This option is ignored and forced to be `true` on the browser. (`true`)
+- `close`
+    - Disconnects the client.
+
+### Transport
+
+The transport class. Private. _Inherits from EventEmitter_.
+
+#### Events
+
+- `poll`: emitted by polling transports upon starting a new request
+- `pollComplete`: emitted by polling transports upon completing a request
+- `drain`: emitted by polling transports upon a buffer drain
+
+## Tests
+
+`engine.io-client` is used to test
+[engine](http://github.com/socketio/engine.io). Running the `engine.io`
+test suite ensures the client works and vice-versa.
+
+Browser tests are run using [zuul](https://github.com/defunctzombie/zuul). You can
+run the tests locally using the following command.
+
+```
+./node_modules/.bin/zuul --local 8080 -- test/index.js
+```
+
+Additionally, `engine.io-client` has a standalone test suite you can run
+with `make test` which will run node.js and browser tests. You must have zuul setup with
+a saucelabs account.
+
+## Support
+
+The support channels for `engine.io-client` are the same as `socket.io`:
+  - irc.freenode.net **#socket.io**
+  - [Google Groups](http://groups.google.com/group/socket_io)
+  - [Website](http://socket.io)
+
+## Development
+
+To contribute patches, run tests or benchmarks, make sure to clone the
+repository:
+
+```bash
+git clone git://github.com/socketio/engine.io-client.git
+```
+
+Then:
+
+```bash
+cd engine.io-client
+npm install
+```
+
+See the `Tests` section above for how to run tests before submitting any patches.

+
+ws is a simple to use, blazing fast, and thoroughly tested WebSocket client
+and server implementation.
+
+Passes the quite extensive Autobahn test suite: [server][server-report],
+[client][client-report].
+
+**Note**: This module does not work in the browser. The client in the docs is a
+reference to a back end with the role of a client in the WebSocket
+communication. Browser clients must use the native
+[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket) object.

+## Protocol support
+
+* **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
+* **HyBi drafts 13-17** (Current default, alternatively option `protocolVersion: 13`)
+
+## Installing
+
+```
+npm install --save ws
+```
+
+### Opt-in for performance and spec compliance
+
+There are 2 optional modules that can be installed along side with the ws
+module. These modules are binary addons which improve certain operations.
+Prebuilt binaries are available for the most popular platforms so you don't
+necessarily need to have a C++ compiler installed on your machine.
+
+- `npm install --save-optional bufferutil`: Allows to efficiently perform
+  operations such as masking and unmasking the data payload of the WebSocket
+  frames.
+- `npm install --save-optional utf-8-validate`: Allows to efficiently check
+  if a message contains valid UTF-8 as required by the spec.
+
+## API docs
+
+See [`/doc/ws.md`](./doc/ws.md) for Node.js-like docs for the ws classes.
+
+## WebSocket compression
+
+ws supports the [permessage-deflate extension][permessage-deflate] which
+enables the client and server to negotiate a compression algorithm and its
+parameters, and then selectively apply it to the data payloads of each
+WebSocket message.
+
+The extension is disabled by default on the server and enabled by default on
+the client. It adds a significant overhead in terms of performance and memory
+consumption so we suggest to enable it only if it is really needed.
+
+The client will only use the extension if it is supported and enabled on the
+server. To always disable the extension on the client set the
+`perMessageDeflate` option to `false`.
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path', {
+  perMessageDeflate: false
+});
+```
+
+## Usage examples
+
+### Sending and receiving text data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+  ws.send('something');
+});
+
+ws.on('message', function incoming(data) {
+  console.log(data);
+});
+```
+
+### Sending binary data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+  const array = new Float32Array(5);
+
+  for (var i = 0; i < array.length; ++i) {
+    array[i] = i / 2;
+  }
+
+  ws.send(array);
+});
+```
+
+### Server example
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(message) {
+    console.log('received: %s', message);
+  });
+
+  ws.send('something');
+});
+```
+
+### Broadcast example
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+// Broadcast to all.
+wss.broadcast = function broadcast(data) {
+  wss.clients.forEach(function each(client) {
+    if (client.readyState === WebSocket.OPEN) {
+      client.send(data);
+    }
+  });
+};
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(data) {
+    // Broadcast to everyone else.
+    wss.clients.forEach(function each(client) {
+      if (client !== ws && client.readyState === WebSocket.OPEN) {
+        client.send(data);
+      }
+    });
+  });
+});
+```
+
+### ExpressJS example
+
+```js
+const express = require('express');
+const http = require('http');
+const url = require('url');
+const WebSocket = require('ws');
+
+const app = express();
+
+app.use(function (req, res) {
+  res.send({ msg: "hello" });
+});
+
+const server = http.createServer(app);
+const wss = new WebSocket.Server({ server });
+
+wss.on('connection', function connection(ws, req) {
+  const location = url.parse(req.url, true);
+  // You might use location.query.access_token to authenticate or share sessions
+  // or req.headers.cookie (see http://stackoverflow.com/a/16395220/151312)
+
+  ws.on('message', function incoming(message) {
+    console.log('received: %s', message);
+  });
+
+  ws.send('something');
+});
+
+server.listen(8080, function listening() {
+  console.log('Listening on %d', server.address().port);
+});
+```
+
+### echo.websocket.org demo
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+  origin: 'https://websocket.org'
+});
+
+ws.on('open', function open() {
+  console.log('connected');
+  ws.send(Date.now());
+});
+
+ws.on('close', function close() {
+  console.log('disconnected');
+});
+
+ws.on('message', function incoming(data) {
+  console.log(`Roundtrip time: ${Date.now() - data} ms`);
+
+  setTimeout(function timeout() {
+    ws.send(Date.now());
+  }, 500);
+});
+```
+
+### Other examples
+
+For a full example with a browser client communicating with a ws server, see the
+examples folder.
+
+Otherwise, see the test cases.
+
+## Error handling best practices
+
+```js
+// If the WebSocket is closed before the following send is attempted
+ws.send('something');
+
+// Errors (both immediate and async write errors) can be detected in an optional
+// callback. The callback is also the only way of being notified that data has
+// actually been sent.
+ws.send('something', function ack(error) {
+  // If error is not defined, the send has been completed, otherwise the error
+  // object will indicate what failed.
+});
+
+// Immediate errors can also be handled with `try...catch`, but **note** that
+// since sends are inherently asynchronous, socket write failures will *not* be
+// captured when this technique is used.
+try { ws.send('something'); }
+catch (e) { /* handle error */ }
+```
+
+## FAQ
+
+### How to get the IP address of the client?
+
+The remote IP address can be obtained from the raw socket.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws, req) {
+  const ip = req.connection.remoteAddress;
+});
+```
+
+When the server runs behind a proxy like NGINX, the de-facto standard is to use
+the `X-Forwarded-For` header.
+
+```js
+wss.on('connection', function connection(ws, req) {
+  const ip = req.headers['x-forwarded-for'];
+});
+```
+
+### How to detect and close broken connections?
+
+Sometimes the link between the server and the client can be interrupted in a
+way that keeps both the server and the client unaware of the broken state of the
+connection (e.g. when pulling the cord).
+
+In these cases ping messages can be used as a means to verify that the remote
+endpoint is still responsive.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+function heartbeat() {
+  this.isAlive = true;
+}
+
+wss.on('connection', function connection(ws) {
+  ws.isAlive = true;
+  ws.on('pong', heartbeat);
+});
+
+const interval = setInterval(function ping() {
+  wss.clients.forEach(function each(ws) {
+    if (ws.isAlive === false) return ws.terminate();
+
+    ws.isAlive = false;
+    ws.ping('', false, true);
+  });
+}, 30000);
+```
+
+Pong messages are automatically sent in response to ping messages as required
+by the spec.
+
+### How to connect via a proxy?
+
+Use a custom `http.Agent` implementation like [https-proxy-agent][] or
+[socks-proxy-agent][].

+# engine.io-parser
+
+[![Build Status](https://secure.travis-ci.org/socketio/engine.io-parser.svg)](http://travis-ci.org/socketio/engine.io-parser)
+[![NPM version](https://badge.fury.io/js/engine.io-parser.svg)](http://badge.fury.io/js/engine.io-parser)
+
+This is the JavaScript parser for the engine.io protocol encoding,
+shared by both
+[engine.io-client](https://github.com/socketio/engine.io-client) and
+[engine.io](https://github.com/socketio/engine.io).
+
+## How to use
+
+### Standalone
+
+The parser can encode/decode packets, payloads, and payloads as binary
+with the following methods: `encodePacket`, `decodePacket`, `encodePayload`,
+`decodePayload`, `encodePayloadAsBinary`, `decodePayloadAsBinary`.
+
+The browser-side parser also includes `encodePayloadAsArrayBuffer` and `encodePayloadAsBlob`.
+
+Example:
+
+```js
+var parser = require('engine.io-parser');
+
+var data = new Buffer(5);
+for (var i = 0; i < data.length; i++) { data[i] = i; }
+
+parser.encodePacket({ type: 'message', data: data }, function(encoded) {
+  var decodedData = parser.decodePacket(encoded); // { type: 'message', data: data }
+});
+```
+
+### With browserify
+
+Engine.IO Parser is a commonjs module, which means you can include it by using
+`require` on the browser and package using [browserify](http://browserify.org/):
+
+1. install the parser package
+
+    ```shell
+    npm install engine.io-parser
+    ```
+
+1. write your app code
+
+    ```js
+    var parser = require('engine.io-parser');
+
+    var testBuffer = new Int8Array(10);
+    for (var i = 0; i < testBuffer.length; i++) testBuffer[i] = i;
+
+    var packets = [{ type: 'message', data: testBuffer.buffer }, { type: 'message', data: 'hello' }];
+
+    parser.encodePayload(packets, function(encoded) {
+      parser.decodePayload(encoded,
+        function(packet, index, total) {
+          var isLast = index + 1 == total;
+          if (!isLast) {
+            var buffer = new Int8Array(packet.data); // testBuffer
+          } else {
+            var message = packet.data; // 'hello'
+          }
+        });
+    });
+    ```
+
+1. build your app bundle
+
+    ```bash
+    $ browserify app.js > bundle.js
+    ```
+
+1. include on your page
+
+    ```html
+    <script src="/path/to/bundle.js"></script>
+    ```
+
+## Features
+
+- Runs on browser and node.js seamlessly
+- Runs inside HTML5 WebWorker
+- Can encode and decode packets
+  - Encodes from/to ArrayBuffer or Blob when in browser, and Buffer or ArrayBuffer in Node
+
+## API
+
+Note: `cb(type)` means the type is a callback function that contains a parameter of type `type` when called.
+
+### Node
+
+- `encodePacket`
+    - Encodes a packet.
+    - **Parameters**
+      - `Object`: the packet to encode, has `type` and `data`.
+        - `data`: can be a `String`, `Number`, `Buffer`, `ArrayBuffer`
+      - `Boolean`: optional, binary support
+      - `Function`: callback, returns the encoded packet (`cb(String)`)
+- `decodePacket`
+    - Decodes a packet. Data also available as an ArrayBuffer if requested.
+    - Returns data as `String` or (`Blob` on browser, `ArrayBuffer` on Node)
+    - **Parameters**
+      - `String` | `ArrayBuffer`: the packet to decode, has `type` and `data`
+      - `String`: optional, the binary type
+
+- `encodeBase64Packet`
+    - Encodes a packet with binary data in a base64 string (`String`)
+    - **Parameters**
+      - `Object`: the packet to encode, has `type` and `data`
+      - `Function`: callback, returns the base64 encoded message (`cb(String)`)
+- `decodeBase64Packet`
+    - Decodes a packet encoded in a base64 string.
+    - **Parameters**
+      - `String`: the base64 encoded message
+      - `String`: optional, the binary type
+
+- `encodePayload`
+    - Encodes multiple messages (payload).
+    - If any contents are binary, they will be encoded as base64 strings. Base64
+      encoded strings are marked with a b before the length specifier
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Boolean`: optional, binary support
+      - `Function`: callback, returns the encoded payload (`cb(String)`)
+- `decodePayload`
+    - Decodes data when a payload is maybe expected. Possible binary contents are
+      decoded from their base64 representation.
+    - **Parameters**
+      - `String`: the payload
+      - `String`: optional, the binary type
+      - `Function`: callback, returns (cb(`Object`: packet, `Number`:packet index, `Number`:packet total))
+
+- `encodePayloadAsBinary`
+    - Encodes multiple messages (payload) as binary.
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Function`: callback, returns the encoded payload (`cb(Buffer)`)
+- `decodePayloadAsBinary`
+    - Decodes data when a payload is maybe expected. Strings are decoded by
+      interpreting each byte as a key code for entries marked to start with 0. See
+      description of encodePayloadAsBinary.
+    - **Parameters**
+      - `Buffer`: the buffer
+      - `String`: optional, the binary type
+      - `Function`: callback, returns the decoded packet (`cb(Object)`)
+
+### Browser
+
+- `encodePayloadAsArrayBuffer`
+    - Encodes multiple messages (payload) as binary.
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Function`: callback, returns the encoded payload (`cb(ArrayBuffer)`)
+- `encodePayloadAsBlob`
+    - Encodes multiple messages (payload) as blob.
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Function`: callback, returns the encoded payload (`cb(Blob)`)
+
+## Tests
+
+Standalone tests can be run with `make test` which will run both node.js and browser tests.
+
+Browser tests are run using [zuul](https://github.com/defunctzombie/zuul).
+(You must have zuul setup with a saucelabs account.)
+
+You can run the tests locally using the following command:
+
+```
+./node_modules/.bin/zuul --local 8080 -- test/index.js
+```
+
+## Support
+
+The support channels for `engine.io-parser` are the same as `socket.io`:
+  - irc.freenode.net **#socket.io**
+  - [Google Groups](http://groups.google.com/group/socket_io)
+  - [Website](http://socket.io)
+

+# Engine.IO: the realtime engine
+
+[![Build Status](https://travis-ci.org/socketio/engine.io.svg?branch=master)](http://travis-ci.org/socketio/engine.io)
+[![NPM version](https://badge.fury.io/js/engine.io.svg)](http://badge.fury.io/js/engine.io)
+
+`Engine.IO` is the implementation of transport-based
+cross-browser/cross-device bi-directional communication layer for
+[Socket.IO](http://github.com/socketio/socket.io).
+
+## How to use
+
+### Server
+
+#### (A) Listening on a port
+
+```js
+var engine = require('engine.io');
+var server = engine.listen(80);
+
+server.on('connection', function(socket){
+  socket.send('utf 8 string');
+  socket.send(new Buffer([0, 1, 2, 3, 4, 5])); // binary data
+});
+```
+
+#### (B) Intercepting requests for a http.Server
+
+```js
+var engine = require('engine.io');
+var http = require('http').createServer().listen(3000);
+var server = engine.attach(http);
+
+server.on('connection', function (socket) {
+  socket.on('message', function(data){ });
+  socket.on('close', function(){ });
+});
+```
+
+#### (C) Passing in requests
+
+```js
+var engine = require('engine.io');
+var server = new engine.Server();
+
+server.on('connection', function(socket){
+  socket.send('hi');
+});
+
+// …
+httpServer.on('upgrade', function(req, socket, head){
+  server.handleUpgrade(req, socket, head);
+});
+httpServer.on('request', function(req, res){
+  server.handleRequest(req, res);
+});
+```
+
+### Client
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+  var socket = new eio.Socket('ws://localhost/');
+  socket.on('open', function(){
+    socket.on('message', function(data){});
+    socket.on('close', function(){});
+  });
+</script>
+```
+
+For more information on the client refer to the
+[engine-client](http://github.com/learnboost/engine.io-client) repository.
+
+## What features does it have?
+
+- **Maximum reliability**. Connections are established even in the presence of:
+  - proxies and load balancers.
+  - personal firewall and antivirus software.
+  - for more information refer to **Goals** and **Architecture** sections
+- **Minimal client size** aided by:
+  - lazy loading of flash transports.
+  - lack of redundant transports.
+- **Scalable**
+  - load balancer friendly
+- **Future proof**
+- **100% Node.JS core style**
+  - No API sugar (left for higher level projects)
+  - Written in readable vanilla JavaScript
+
+## API
+
+### Server
+
+<hr><br>
+
+#### Top-level
+
+These are exposed by `require('engine.io')`:
+
+##### Events
+
+- `flush`
+    - Called when a socket buffer is being flushed.
+    - **Arguments**
+      - `Socket`: socket being flushed
+      - `Array`: write buffer
+- `drain`
+    - Called when a socket buffer is drained
+    - **Arguments**
+      - `Socket`: socket being flushed
+
+##### Properties
+
+- `protocol` _(Number)_: protocol revision number
+- `Server`: Server class constructor
+- `Socket`: Socket class constructor
+- `Transport` _(Function)_: transport constructor
+- `transports` _(Object)_: map of available transports
+
+##### Methods
+
+- `()`
+    - Returns a new `Server` instance. If the first argument is an `http.Server` then the
+      new `Server` instance will be attached to it. Otherwise, the arguments are passed
+      directly to the `Server` constructor.
+    - **Parameters**
+      - `http.Server`: optional, server to attach to.
+      - `Object`: optional, options object (see `Server#constructor` api docs below)
+
+  The following are identical ways to instantiate a server and then attach it.
+  ```js
+  var httpServer; // previously created with `http.createServer();` from node.js api.
+
+  // create a server first, and then attach
+  var eioServer = require('engine.io').Server();
+  eioServer.attach(httpServer);
+
+  // or call the module as a function to get `Server`
+  var eioServer = require('engine.io')();
+  eioServer.attach(httpServer);
+
+  // immediately attach
+  var eioServer = require('engine.io')(httpServer);
+  ```
+
+- `listen`
+    - Creates an `http.Server` which listens on the given port and attaches WS
+      to it. It returns `501 Not Implemented` for regular http requests.
+    - **Parameters**
+      - `Number`: port to listen on.
+      - `Object`: optional, options object
+      - `Function`: callback for `listen`.
+    - **Options**
+      - All options from `Server.attach` method, documented below.
+      - **Additionally** See Server `constructor` below for options you can pass for creating the new Server
+    - **Returns** `Server`
+- `attach`
+    - Captures `upgrade` requests for a `http.Server`. In other words, makes
+      a regular http.Server WebSocket-compatible.
+    - **Parameters**
+      - `http.Server`: server to attach to.
+      - `Object`: optional, options object
+    - **Options**
+      - All options from `Server.attach` method, documented below.
+      - **Additionally** See Server `constructor` below for options you can pass for creating the new Server
+    - **Returns** `Server` a new Server instance.
+
+<hr><br>
+
+#### Server
+
+The main server/manager. _Inherits from EventEmitter_.
+
+##### Events
+
+- `connection`
+    - Fired when a new connection is established.
+    - **Arguments**
+      - `Socket`: a Socket object
+
+##### Properties
+
+**Important**: if you plan to use Engine.IO in a scalable way, please
+keep in mind the properties below will only reflect the clients connected
+to a single process.
+
+- `clients` _(Object)_: hash of connected clients by id.
+- `clientsCount` _(Number)_: number of connected clients.
+
+##### Methods
+
+- **constructor**
+    - Initializes the server
+    - **Parameters**
+      - `Object`: optional, options object
+    - **Options**
+      - `pingTimeout` (`Number`): how many ms without a pong packet to
+        consider the connection closed (`5000`)
+      - `pingInterval` (`Number`): how many ms before sending a new ping
+        packet (`25000`)
+      - `upgradeTimeout` (`Number`): how many ms before an uncompleted transport upgrade is cancelled (`10000`)
+      - `maxHttpBufferSize` (`Number`): how many bytes or characters a message
+        can be, before closing the session (to avoid DoS). Default
+        value is `10E7`.
+      - `allowRequest` (`Function`): A function that receives a given handshake
+        or upgrade request as its first parameter, and can decide whether to
+        continue or not. The second argument is a function that needs to be
+        called with the decided information: `fn(err, success)`, where
+        `success` is a boolean value where false means that the request is
+        rejected, and err is an error code.
+      - `transports` (`<Array> String`): transports to allow connections
+        to (`['polling', 'websocket']`)
+      - `allowUpgrades` (`Boolean`): whether to allow transport upgrades
+        (`true`)
+      - `perMessageDeflate` (`Object|Boolean`): parameters of the WebSocket permessage-deflate extension
+        (see [ws module](https://github.com/einaros/ws) api docs). Set to `false` to disable. (`true`)
+        - `threshold` (`Number`): data is compressed only if the byte size is above this value (`1024`)
+      - `httpCompression` (`Object|Boolean`): parameters of the http compression for the polling transports
+        (see [zlib](http://nodejs.org/api/zlib.html#zlib_options) api docs). Set to `false` to disable. (`true`)
+        - `threshold` (`Number`): data is compressed only if the byte size is above this value (`1024`)
+      - `cookie` (`String|Boolean`): name of the HTTP cookie that
+        contains the client sid to send as part of handshake response
+        headers. Set to `false` to not send one. (`io`)
+      - `cookiePath` (`String|Boolean`): path of the above `cookie`
+        option. If false, no path will be sent, which means browsers will only send the cookie on the engine.io attached path (`/engine.io`).
+        Set false to not save io cookie on all requests. (`/`)
+      - `cookieHttpOnly` (`Boolean`): If `true` HttpOnly io cookie cannot be accessed by client-side APIs, such as JavaScript. (`true`) _This option has no effect if `cookie` or `cookiePath` is set to `false`._
+      - `wsEngine` (`String`): what WebSocket server implementation to use. Specified module must conform to the `ws` interface (see [ws module api docs](https://github.com/websockets/ws/blob/master/doc/ws.md)). Default value is `ws`.

+      - `Buffer`: legacy tail bytes
+    - **Returns** `Server` for chaining
+- `attach`
+    - Attach this Server instance to an `http.Server`
+    - Captures `upgrade` requests for a `http.Server`. In other words, makes
+      a regular http.Server WebSocket-compatible.
+    - **Parameters**
+      - `http.Server`: server to attach to.
+      - `Object`: optional, options object

+In order to see all the debug output, run your app with the environment variable
+`DEBUG` including the desired scope.
+
+To see the output from all of Engine.IO's debugging scopes you can use:
+
+```
+DEBUG=engine* node myapp
+```
+
+## Transports
+
+- `polling`: XHR / JSONP polling transport.
+- `websocket`: WebSocket transport.
+
+## Plugins
+
+- [engine.io-conflation](https://github.com/EugenDueck/engine.io-conflation): Makes **conflation and aggregation** of messages straightforward.
+
+## Support
+
+The support channels for `engine.io` are the same as `socket.io`:

+## Development
+
+To contribute patches, run tests or benchmarks, make sure to clone the
+repository:
+
+```
+git clone git://github.com/LearnBoost/engine.io.git
+```
+
+Then:
+
+```
+cd engine.io
+npm install
+```
+
+## Tests
+
+Tests run with `npm test`. It runs the server tests that are aided by
+the usage of `engine.io-client`.
+
+Make sure `npm install` is run first.
+
+## Goals
+
+The main goal of `Engine` is ensuring the most reliable realtime communication.
+Unlike the previous Socket.IO core, it always establishes a long-polling
+connection first, then tries to upgrade to better transports that are "tested" on
+the side.
+
+During the lifetime of the Socket.IO projects, we've found countless drawbacks
+to relying on `HTML5 WebSocket` or `Flash Socket` as the first connection
+mechanisms.
+
+Both are clearly the _right way_ of establishing a bidirectional communication,
+with HTML5 WebSocket being the way of the future. However, to answer most business
+needs, alternative traditional HTTP 1.1 mechanisms are just as good as delivering
+the same solution.
+
+WebSocket based connections have two fundamental benefits:
+
+1. **Better server performance**
+  - _A: Load balancers_<br>
+      Load balancing a long polling connection poses a serious architectural nightmare
+      since requests can come from any number of open sockets by the user agent, but
+      they all need to be routed to the process and computer that owns the `Engine`
+      connection. This negatively impacts RAM and CPU usage.
+  - _B: Network traffic_<br>
+      WebSocket is designed around the premise that each message frame has to be
+      surrounded by the least amount of data. In HTTP 1.1 transports, each message
+      frame is surrounded by HTTP headers and chunked encoding frames. If you try to
+      send the message _"Hello world"_ with xhr-polling, the message ultimately
+      becomes larger than if you were to send it with WebSocket.
+  - _C: Lightweight parser_<br>
+      As an effect of **B**, the server has to do a lot more work to parse the network
+      data and figure out the message when traditional HTTP requests are used
+      (as in long polling). This means that another advantage of WebSocket is
+      less server CPU usage.
+
+2. **Better user experience**
+
+    Due to the reasons stated in point **1**, the most important effect of being able
+    to establish a WebSocket connection is raw data transfer speed, which translates
+    in _some_ cases in better user experience.
+
+    Applications with heavy realtime interaction (such as games) will benefit greatly,
+    whereas applications like realtime chat (Gmail/Facebook), newsfeeds (Facebook) or
+    timelines (Twitter) will have negligible user experience improvements.
+
+Having said this, attempting to establish a WebSocket connection directly so far has
+proven problematic:
+
+1. **Proxies**<br>
+    Many corporate proxies block WebSocket traffic.
+
+2. **Personal firewall and antivirus software**<br>
+    As a result of our research, we've found that at least 3 personal security
+    applications block WebSocket traffic.
+
+3. **Cloud application platforms**<br>
+    Platforms like Heroku or No.de have had trouble keeping up with the fast-paced
+    nature of the evolution of the WebSocket protocol. Applications therefore end up
+    inevitably using long polling, but the seamless installation experience of
+    Socket.IO we strive for (_"require() it and it just works"_) disappears.
+
+Some of these problems have solutions. In the case of proxies and personal programs,
+however, the solutions many times involve upgrading software. Experience has shown
+that relying on client software upgrades to deliver a business solution is
+fruitless: the very existence of this project has to do with a fragmented panorama
+of user agent distribution, with clients connecting with latest versions of the most
+modern user agents (Chrome, Firefox and Safari), but others with versions as low as
+IE 5.5.
+
+From the user perspective, an unsuccessful WebSocket connection can translate in
+up to at least 10 seconds of waiting for the realtime application to begin
+exchanging data. This **perceptively** hurts user experience.
+
+To summarize, **Engine** focuses on reliability and user experience first, marginal
+potential UX improvements and increased server performance second. `Engine` is the
+result of all the lessons learned with WebSocket in the wild.
+
+## Architecture
+
+The main premise of `Engine`, and the core of its existence, is the ability to
+swap transports on the fly. A connection starts as xhr-polling, but it can
+switch to WebSocket.
+
+The central problem this poses is: how do we switch transports without losing
+messages?
+
+`Engine` only switches from polling to another transport in between polling
+cycles. Since the server closes the connection after a certain timeout when
+there's no activity, and the polling transport implementation buffers messages
+in between connections, this ensures no message loss and optimal performance.
+
+Another benefit of this design is that we workaround almost all the limitations
+of **Flash Socket**, such as slow connection times, increased file size (we can
+safely lazy load it without hurting user experience), etc.
+
+## FAQ
+
+### Can I use engine without Socket.IO ?
+
+Absolutely. Although the recommended framework for building realtime applications
+is Socket.IO, since it provides fundamental features for real-world applications
+such as multiplexing, reconnection support, etc.
+
+`Engine` is to Socket.IO what Connect is to Express. An essential piece for building
+realtime frameworks, but something you _probably_ won't be using for building
+actual applications.
+
+### Does the server serve the client?
+
+No. The main reason is that `Engine` is meant to be bundled with frameworks.
+Socket.IO includes `Engine`, therefore serving two clients is not necessary. If
+you use Socket.IO, including
+
+```html
+<script src="/socket.io/socket.io.js">
+```
+
+has you covered.
+
+### Can I implement `Engine` in other languages?
+
+Absolutely. The [engine.io-protocol](https://github.com/LearnBoost/engine.io-protocol)
+repository contains the most up to date description of the specification
+at all times, and the parser implementation in JavaScript.

+
+ws is a simple to use, blazing fast, and thoroughly tested WebSocket client
+and server implementation.
+
+Passes the quite extensive Autobahn test suite: [server][server-report],
+[client][client-report].
+
+**Note**: This module does not work in the browser. The client in the docs is a
+reference to a back end with the role of a client in the WebSocket
+communication. Browser clients must use the native
+[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket) object.

+## Protocol support
+
+* **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
+* **HyBi drafts 13-17** (Current default, alternatively option `protocolVersion: 13`)
+
+## Installing
+
+```
+npm install --save ws
+```
+
+### Opt-in for performance and spec compliance
+
+There are 2 optional modules that can be installed along side with the ws
+module. These modules are binary addons which improve certain operations.
+Prebuilt binaries are available for the most popular platforms so you don't
+necessarily need to have a C++ compiler installed on your machine.
+
+- `npm install --save-optional bufferutil`: Allows to efficiently perform
+  operations such as masking and unmasking the data payload of the WebSocket
+  frames.
+- `npm install --save-optional utf-8-validate`: Allows to efficiently check
+  if a message contains valid UTF-8 as required by the spec.
+
+## API docs
+
+See [`/doc/ws.md`](./doc/ws.md) for Node.js-like docs for the ws classes.
+
+## WebSocket compression
+
+ws supports the [permessage-deflate extension][permessage-deflate] which
+enables the client and server to negotiate a compression algorithm and its
+parameters, and then selectively apply it to the data payloads of each
+WebSocket message.
+
+The extension is disabled by default on the server and enabled by default on
+the client. It adds a significant overhead in terms of performance and memory
+consumption so we suggest to enable it only if it is really needed.
+
+The client will only use the extension if it is supported and enabled on the
+server. To always disable the extension on the client set the
+`perMessageDeflate` option to `false`.
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path', {
+  perMessageDeflate: false
+});
+```
+
+## Usage examples
+
+### Sending and receiving text data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+  ws.send('something');
+});
+
+ws.on('message', function incoming(data) {
+  console.log(data);
+});
+```
+
+### Sending binary data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+  const array = new Float32Array(5);
+
+  for (var i = 0; i < array.length; ++i) {
+    array[i] = i / 2;
+  }
+
+  ws.send(array);
+});
+```
+
+### Server example
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(message) {
+    console.log('received: %s', message);
+  });
+
+  ws.send('something');
+});
+```
+
+### Broadcast example
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+// Broadcast to all.
+wss.broadcast = function broadcast(data) {
+  wss.clients.forEach(function each(client) {
+    if (client.readyState === WebSocket.OPEN) {
+      client.send(data);
+    }
+  });
+};
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(data) {
+    // Broadcast to everyone else.
+    wss.clients.forEach(function each(client) {
+      if (client !== ws && client.readyState === WebSocket.OPEN) {
+        client.send(data);
+      }
+    });
+  });
+});
+```
+
+### ExpressJS example
+
+```js
+const express = require('express');
+const http = require('http');
+const url = require('url');
+const WebSocket = require('ws');
+
+const app = express();
+
+app.use(function (req, res) {
+  res.send({ msg: "hello" });
+});
+
+const server = http.createServer(app);
+const wss = new WebSocket.Server({ server });
+
+wss.on('connection', function connection(ws, req) {
+  const location = url.parse(req.url, true);
+  // You might use location.query.access_token to authenticate or share sessions
+  // or req.headers.cookie (see http://stackoverflow.com/a/16395220/151312)
+
+  ws.on('message', function incoming(message) {
+    console.log('received: %s', message);
+  });
+
+  ws.send('something');
+});
+
+server.listen(8080, function listening() {
+  console.log('Listening on %d', server.address().port);
+});
+```
+
+### echo.websocket.org demo
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+  origin: 'https://websocket.org'
+});
+
+ws.on('open', function open() {
+  console.log('connected');
+  ws.send(Date.now());
+});
+
+ws.on('close', function close() {
+  console.log('disconnected');
+});
+
+ws.on('message', function incoming(data) {
+  console.log(`Roundtrip time: ${Date.now() - data} ms`);
+
+  setTimeout(function timeout() {
+    ws.send(Date.now());
+  }, 500);
+});
+```
+
+### Other examples
+
+For a full example with a browser client communicating with a ws server, see the
+examples folder.
+
+Otherwise, see the test cases.
+
+## Error handling best practices
+
+```js
+// If the WebSocket is closed before the following send is attempted
+ws.send('something');
+
+// Errors (both immediate and async write errors) can be detected in an optional
+// callback. The callback is also the only way of being notified that data has
+// actually been sent.
+ws.send('something', function ack(error) {
+  // If error is not defined, the send has been completed, otherwise the error
+  // object will indicate what failed.
+});
+
+// Immediate errors can also be handled with `try...catch`, but **note** that
+// since sends are inherently asynchronous, socket write failures will *not* be
+// captured when this technique is used.
+try { ws.send('something'); }
+catch (e) { /* handle error */ }
+```
+
+## FAQ
+
+### How to get the IP address of the client?
+
+The remote IP address can be obtained from the raw socket.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws, req) {
+  const ip = req.connection.remoteAddress;
+});
+```
+
+When the server runs behind a proxy like NGINX, the de-facto standard is to use
+the `X-Forwarded-For` header.
+
+```js
+wss.on('connection', function connection(ws, req) {
+  const ip = req.headers['x-forwarded-for'];
+});
+```
+
+### How to detect and close broken connections?
+
+Sometimes the link between the server and the client can be interrupted in a
+way that keeps both the server and the client unaware of the broken state of the
+connection (e.g. when pulling the cord).
+
+In these cases ping messages can be used as a means to verify that the remote
+endpoint is still responsive.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+function heartbeat() {
+  this.isAlive = true;
+}
+
+wss.on('connection', function connection(ws) {
+  ws.isAlive = true;
+  ws.on('pong', heartbeat);
+});
+
+const interval = setInterval(function ping() {
+  wss.clients.forEach(function each(ws) {
+    if (ws.isAlive === false) return ws.terminate();
+
+    ws.isAlive = false;
+    ws.ping('', false, true);
+  });
+}, 30000);
+```
+
+Pong messages are automatically sent in response to ping messages as required
+by the spec.
+
+### How to connect via a proxy?
+
+Use a custom `http.Agent` implementation like [https-proxy-agent][] or
+[socks-proxy-agent][].

+
+[![Sauce Test Status](https://saucelabs.com/browser-matrix/eventemitter3.svg)](https://saucelabs.com/u/eventemitter3)
+
+EventEmitter3 is a high performance EventEmitter. It has been micro-optimized
+for various of code paths making this, one of, if not the fastest EventEmitter
+available for Node.js and browsers. The module is API compatible with the
+EventEmitter that ships by default with Node.js but there are some slight
+differences:
+
+- Domain support has been removed.
+- We do not `throw` an error when you emit an `error` event and nobody is
+  listening.
+- The `newListener` and `removeListener` events have been removed as they
+  are useful only in some uncommon use-cases.
+- The `setMaxListeners`, `getMaxListeners`, `prependListener` and
+  `preperndOnceListener` methods are not available.
+- Support for custom context for events so there is no need to use `fn.bind`.
+- The `removeListener` method removes all matching listeners, not only the
+  first.
+
+It's a drop in replacement for existing EventEmitters, but just faster. Free
+performance, who wouldn't want that? The EventEmitter is written in EcmaScript 3
+so it will work in the oldest browsers and node versions that you need to
+support.
+
+## Installation
+
+```bash
+$ npm install --save eventemitter3
+```
+
+## CDN
+
+Recommended CDN:
+
+```text
+https://unpkg.com/eventemitter3@latest/umd/eventemitter3.min.js
+```
+
+## Usage
+
+After installation the only thing you need to do is require the module:
+
+```js
+var EventEmitter = require('eventemitter3');
+```
+
+And you're ready to create your own EventEmitter instances. For the API
+documentation, please follow the official Node.js documentation:
+
+http://nodejs.org/api/events.html
+
+### Contextual emits
+
+We've upgraded the API of the `EventEmitter.on`, `EventEmitter.once` and
+`EventEmitter.removeListener` to accept an extra argument which is the `context`
+or `this` value that should be set for the emitted events. This means you no
+longer have the overhead of an event that required `fn.bind` in order to get a
+custom `this` value.
+
+```js
+var EE = new EventEmitter()
+  , context = { foo: 'bar' };
+
+function emitted() {
+  console.log(this === context); // true
+}
+
+EE.once('event-name', emitted, context);
+EE.on('another-event', emitted, context);
+EE.removeListener('another-event', emitted, context);
+```
+
+### Tests and benchmarks
+
+This module is well tested. You can run:
+
+- `npm test` to run the tests under Node.js.
+- `npm run test-browser` to run the tests in real browsers via Sauce Labs.
+
+We also have a set of benchmarks to compare EventEmitter3 with some available
+alternatives. To run the benchmarks run `npm run benchmark`.
+
+Tests and benchmarks are not included in the npm package. If you want to play
+with them you have to clone the GitHub repository.

+## Follow Redirects
+
+Drop-in replacement for Nodes `http` and `https` that automatically follows redirects.
+
+[![npm version](https://badge.fury.io/js/follow-redirects.svg)](https://www.npmjs.com/package/follow-redirects)
+[![Build Status](https://travis-ci.org/olalonde/follow-redirects.svg?branch=master)](https://travis-ci.org/olalonde/follow-redirects)
+[![Coverage Status](https://coveralls.io/repos/olalonde/follow-redirects/badge.svg?branch=master)](https://coveralls.io/r/olalonde/follow-redirects?branch=master)
+[![Dependency Status](https://david-dm.org/olalonde/follow-redirects.svg)](https://david-dm.org/olalonde/follow-redirects)
+[![devDependency Status](https://david-dm.org/olalonde/follow-redirects/dev-status.svg)](https://david-dm.org/olalonde/follow-redirects#info=devDependencies)
+
+[![NPM](https://nodei.co/npm/follow-redirects.png?downloads=true)](https://nodei.co/npm/follow-redirects/)
+
+`follow-redirects` provides [request](https://nodejs.org/api/http.html#http_http_request_options_callback) and [get](https://nodejs.org/api/http.html#http_http_get_options_callback)
+ methods that behave identically to those found on the native [http](https://nodejs.org/api/http.html#http_http_request_options_callback) and [https](https://nodejs.org/api/https.html#https_https_request_options_callback)
+ modules, with the exception that they will seamlessly follow redirects.
+
+```javascript
+var http = require('follow-redirects').http;
+var https = require('follow-redirects').https;
+
+http.get('http://bit.ly/900913', function (response) {
+  response.on('data', function (chunk) {
+    console.log(chunk);
+  });
+}).on('error', function (err) {
+  console.error(err);
+});
+```
+
+You can inspect the final redirected URL through the `responseUrl` property on the `response`.
+If no redirection happened, `responseUrl` is the original request URL.
+
+```javascript
+https.request({
+  host: 'bitly.com',
+  path: '/UHfDGO',
+}, function (response) {
+  console.log(response.responseUrl);
+  // 'http://duckduckgo.com/robots.txt'
+});
+```
+
+## Options
+### Global options
+Global options are set directly on the `follow-redirects` module:
+
+```javascript
+var followRedirects = require('follow-redirects');
+followRedirects.maxRedirects = 10;
+followRedirects.maxBodyLength = 20 * 1024 * 1024; // 20 MB
+```
+
+The following global options are supported:
+
+- `maxRedirects` (default: `21`) – sets the maximum number of allowed redirects; if exceeded, an error will be emitted.
+
+- `maxBodyLength` (default: 10MB) – sets the maximum size of the request body; if exceeded, an error will be emitted.
+
+
+### Per-request options
+Per-request options are set by passing an `options` object:
+
+```javascript
+var url = require('url');
+var followRedirects = require('follow-redirects');
+
+var options = url.parse('http://bit.ly/900913');
+options.maxRedirects = 10;
+http.request(options);
+```
+
+In addition to the [standard HTTP](https://nodejs.org/api/http.html#http_http_request_options_callback) and [HTTPS options](https://nodejs.org/api/https.html#https_https_request_options_callback),
+the following per-request options are supported:
+- `followRedirects` (default: `true`) – whether redirects should be followed.
+
+- `maxRedirects` (default: `21`) – sets the maximum number of allowed redirects; if exceeded, an error will be emitted.
+
+- `maxBodyLength` (default: 10MB) – sets the maximum size of the request body; if exceeded, an error will be emitted.
+
+- `agents` (default: `undefined`) – sets the `agent` option per protocol, since HTTP and HTTPS use different agents. Example value: `{ http: new http.Agent(), https: new https.Agent() }`
+
+- `trackRedirects` (default: `false`) – whether to store the redirected response details into the `redirects` array on the response object.
+
+
+### Advanced usage
+By default, `follow-redirects` will use the Node.js default implementations
+of [`http`](https://nodejs.org/api/http.html)
+and [`https`](https://nodejs.org/api/https.html).
+To enable features such as caching and/or intermediate request tracking,
+you might instead want to wrap `follow-redirects` around custom protocol implementations:
+
+```javascript
+var followRedirects = require('follow-redirects').wrap({
+  http: require('your-custom-http'),
+  https: require('your-custom-https'),
+});
+```
+
+Such custom protocols only need an implementation of the `request` method.
+
+## Browserify Usage
+
+Due to the way `XMLHttpRequest` works, the `browserify` versions of `http` and `https` already follow redirects.
+ If you are *only* targeting the browser, then this library has little value for you. If you want to write cross
+ platform code for node and the browser, `follow-redirects` provides a great solution for making the native node
+ modules behave the same as they do in browserified builds in the browser. To avoid bundling unnecessary code
+ you should tell browserify to swap out `follow-redirects` with the standard modules when bundling.
+ To make this easier, you need to change how you require the modules:
+
+```javascript
+var http = require('follow-redirects/http');
+var https = require('follow-redirects/https');
+```
+
+You can then replace `follow-redirects` in your browserify configuration like so:
+
+```javascript
+"browser": {
+  "follow-redirects/http"  : "http",
+  "follow-redirects/https" : "https"
+}
+```
+
+The `browserify-http` module has not kept pace with node development, and no long behaves identically to the native
+ module when running in the browser. If you are experiencing problems, you may want to check out
+ [browserify-http-2](https://www.npmjs.com/package/http-browserify-2). It is more actively maintained and
+ attempts to address a few of the shortcomings of `browserify-http`. In that case, your browserify config should
+ look something like this:
+
+```javascript
+"browser": {
+  "follow-redirects/http"  : "browserify-http-2/http",
+  "follow-redirects/https" : "browserify-http-2/https"
+}
+```
+
+## Contributing
+
+Pull Requests are always welcome. Please [file an issue](https://github.com/olalonde/follow-redirects/issues)
+ detailing your proposal before you invest your valuable time. Additional features and bug fixes should be accompanied
+ by tests. You can run the test suite locally with a simple `npm test` command.
+
+## Debug Logging
+
+`follow-redirects` uses the excellent [debug](https://www.npmjs.com/package/debug) for logging. To turn on logging
+ set the environment variable `DEBUG=follow-redirects` for debug output from just this module. When running the test
+ suite it is sometimes advantageous to set `DEBUG=*` to see output from the express server as well.

+# Glob
+
+Match files using the patterns the shell uses, like stars and stuff.
+
+[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
+
+This is a glob implementation in JavaScript.  It uses the `minimatch`
+library to do its matching.
+
+![](oh-my-glob.gif)
+
+## Usage
+
+```javascript
+var glob = require("glob")
+
+// options is optional
+glob("**/*.js", options, function (er, files) {
+  // files is an array of filenames.
+  // If the `nonull` option is set, and nothing
+  // was found, then files is ["**/*.js"]
+  // er is an error object or null.
+})
+```
+
+## Glob Primer
+
+"Globs" are the patterns you type when you do stuff like `ls *.js` on
+the command line, or put `build/*` in a `.gitignore` file.
+
+Before parsing the path part patterns, braced sections are expanded
+into a set.  Braced sections start with `{` and end with `}`, with any
+number of comma-delimited sections within.  Braced sections may contain
+slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
+
+The following characters have special magic meaning when used in a
+path portion:
+
+* `*` Matches 0 or more characters in a single path portion
+* `?` Matches 1 character
+* `[...]` Matches a range of characters, similar to a RegExp range.
+  If the first character of the range is `!` or `^` then it matches
+  any character not in the range.
+* `!(pattern|pattern|pattern)` Matches anything that does not match
+  any of the patterns provided.
+* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
+  patterns provided.
+* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
+  patterns provided.
+* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
+* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
+  provided
+* `**` If a "globstar" is alone in a path portion, then it matches
+  zero or more directories and subdirectories searching for matches.
+  It does not crawl symlinked directories.
+
+### Dots
+
+If a file or directory path portion has a `.` as the first character,
+then it will not match any glob pattern unless that pattern's
+corresponding path part also has a `.` as its first character.
+
+For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
+However the pattern `a/*/c` would not, because `*` does not start with
+a dot character.
+
+You can make glob treat dots as normal characters by setting
+`dot:true` in the options.
+
+### Basename Matching
+
+If you set `matchBase:true` in the options, and the pattern has no
+slashes in it, then it will seek for any file anywhere in the tree
+with a matching basename.  For example, `*.js` would match
+`test/simple/basic.js`.
+
+### Empty Sets
+
+If no matching files are found, then an empty array is returned.  This
+differs from the shell, where the pattern itself is returned.  For
+example:
+
+    $ echo a*s*d*f
+    a*s*d*f
+
+To get the bash-style behavior, set the `nonull:true` in the options.
+
+### See Also:
+
+* `man sh`
+* `man bash` (Search for "Pattern Matching")
+* `man 3 fnmatch`
+* `man 5 gitignore`
+* [minimatch documentation](https://github.com/isaacs/minimatch)
+
+## glob.hasMagic(pattern, [options])
+
+Returns `true` if there are any special characters in the pattern, and
+`false` otherwise.
+
+Note that the options affect the results.  If `noext:true` is set in
+the options object, then `+(a|b)` will not be considered a magic
+pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
+then that is considered magical, unless `nobrace:true` is set in the
+options.
+
+## glob(pattern, [options], cb)
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* `cb` `{Function}`
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Perform an asynchronous glob search.
+
+## glob.sync(pattern, [options])
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* return: `{Array<String>}` filenames found matching the pattern
+
+Perform a synchronous glob search.
+
+## Class: glob.Glob
+
+Create a Glob object by instantiating the `glob.Glob` class.
+
+```javascript
+var Glob = require("glob").Glob
+var mg = new Glob(pattern, options, cb)
+```
+
+It's an EventEmitter, and starts walking the filesystem to find matches
+immediately.
+
+### new glob.Glob(pattern, [options], [cb])
+
+* `pattern` `{String}` pattern to search for
+* `options` `{Object}`
+* `cb` `{Function}` Called when an error occurs, or matches are found
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Note that if the `sync` flag is set in the options, then matches will
+be immediately available on the `g.found` member.
+
+### Properties
+
+* `minimatch` The minimatch object that the glob uses.
+* `options` The options object passed in.
+* `aborted` Boolean which is set to true when calling `abort()`.  There
+  is no way at this time to continue a glob search after aborting, but
+  you can re-use the statCache to avoid having to duplicate syscalls.
+* `cache` Convenience object.  Each field has the following possible
+  values:
+  * `false` - Path does not exist
+  * `true` - Path exists
+  * `'FILE'` - Path exists, and is not a directory
+  * `'DIR'` - Path exists, and is a directory
+  * `[file, entries, ...]` - Path exists, is a directory, and the
+    array value is the results of `fs.readdir`
+* `statCache` Cache of `fs.stat` results, to prevent statting the same
+  path multiple times.
+* `symlinks` A record of which paths are symbolic links, which is
+  relevant in resolving `**` patterns.
+* `realpathCache` An optional object which is passed to `fs.realpath`
+  to minimize unnecessary syscalls.  It is stored on the instantiated
+  Glob object, and may be re-used.
+
+### Events
+
+* `end` When the matching is finished, this is emitted with all the
+  matches found.  If the `nonull` option is set, and no match was found,
+  then the `matches` list contains the original pattern.  The matches
+  are sorted, unless the `nosort` flag is set.
+* `match` Every time a match is found, this is emitted with the specific
+  thing that matched. It is not deduplicated or resolved to a realpath.
+* `error` Emitted when an unexpected error is encountered, or whenever
+  any fs error occurs if `options.strict` is set.
+* `abort` When `abort()` is called, this event is raised.
+
+### Methods
+
+* `pause` Temporarily stop the search
+* `resume` Resume the search
+* `abort` Stop the search forever
+
+### Options
+
+All the options that can be passed to Minimatch can also be passed to
+Glob to change pattern matching behavior.  Also, some have been added,
+or have glob-specific ramifications.
+
+All options are false by default, unless otherwise noted.
+
+All options are added to the Glob object, as well.
+
+If you are running many `glob` operations, you can pass a Glob object
+as the `options` argument to a subsequent operation to shortcut some
+`stat` and `readdir` calls.  At the very least, you may pass in shared
+`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
+parallel glob operations will be sped up by sharing information about
+the filesystem.
+
+* `cwd` The current working directory in which to search.  Defaults
+  to `process.cwd()`.
+* `root` The place where patterns starting with `/` will be mounted
+  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
+  systems, and `C:\` or some such on Windows.)
+* `dot` Include `.dot` files in normal matches and `globstar` matches.
+  Note that an explicit dot in a portion of the pattern will always
+  match dot files.
+* `nomount` By default, a pattern starting with a forward-slash will be
+  "mounted" onto the root setting, so that a valid filesystem path is
+  returned.  Set this flag to disable that behavior.
+* `mark` Add a `/` character to directory matches.  Note that this
+  requires additional stat calls.
+* `nosort` Don't sort the results.
+* `stat` Set to true to stat *all* results.  This reduces performance
+  somewhat, and is completely unnecessary, unless `readdir` is presumed
+  to be an untrustworthy indicator of file existence.
+* `silent` When an unusual error is encountered when attempting to
+  read a directory, a warning will be printed to stderr.  Set the
+  `silent` option to true to suppress these warnings.
+* `strict` When an unusual error is encountered when attempting to
+  read a directory, the process will just continue on in search of
+  other matches.  Set the `strict` option to raise an error in these
+  cases.
+* `cache` See `cache` property above.  Pass in a previously generated
+  cache object to save some fs calls.
+* `statCache` A cache of results of filesystem information, to prevent
+  unnecessary stat calls.  While it should not normally be necessary
+  to set this, you may pass the statCache from one glob() call to the
+  options object of another, if you know that the filesystem will not
+  change between calls.  (See "Race Conditions" below.)
+* `symlinks` A cache of known symbolic links.  You may pass in a
+  previously generated `symlinks` object to save `lstat` calls when
+  resolving `**` matches.
+* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
+* `nounique` In some cases, brace-expanded patterns can result in the
+  same file showing up multiple times in the result set.  By default,
+  this implementation prevents duplicates in the result set.  Set this
+  flag to disable that behavior.
+* `nonull` Set to never return an empty set, instead returning a set
+  containing the pattern itself.  This is the default in glob(3).
+* `debug` Set to enable debug logging in minimatch and glob.
+* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
+* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
+  treat it as a normal `*` instead.)
+* `noext` Do not match `+(a|b)` "extglob" patterns.
+* `nocase` Perform a case-insensitive match.  Note: on
+  case-insensitive filesystems, non-magic patterns will match by
+  default, since `stat` and `readdir` will not raise errors.
+* `matchBase` Perform a basename-only match if the pattern does not
+  contain any slash characters.  That is, `*.js` would be treated as
+  equivalent to `**/*.js`, matching all js files in all directories.
+* `nodir` Do not match directories, only files.  (Note: to match
+  *only* directories, simply put a `/` at the end of the pattern.)
+* `ignore` Add a pattern or an array of glob patterns to exclude matches.
+  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
+  of any other settings.
+* `follow` Follow symlinked directories when expanding `**` patterns.
+  Note that this can result in a lot of duplicate references in the
+  presence of cyclic links.
+* `realpath` Set to true to call `fs.realpath` on all of the results.
+  In the case of a symlink that cannot be resolved, the full absolute
+  path to the matched entry is returned (though it will usually be a
+  broken symlink)
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between node-glob and other
+implementations, and are intentional.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.3, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+Note that symlinked directories are not crawled as part of a `**`,
+though their contents may match against subsequent portions of the
+pattern.  This prevents infinite loops and duplicates and the like.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then glob returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.
+
+### Comments and Negation
+
+Previously, this module let you mark a pattern as a "comment" if it
+started with a `#` character, or a "negated" pattern if it started
+with a `!` character.
+
+These options were deprecated in version 5, and removed in version 6.
+
+To specify things that should not match, use the `ignore` option.
+
+## Windows
+
+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes will always
+be interpreted as escape characters, not path separators.
+
+Results from absolute patterns such as `/foo/*` are mounted onto the
+root setting using `path.join`.  On windows, this will by default result
+in `/foo/*` matching `C:\foo\bar.txt`.
+
+## Race Conditions
+
+Glob searching, by its very nature, is susceptible to race conditions,
+since it relies on directory walking and such.
+
+As a result, it is possible that a file that exists when glob looks for
+it may have been deleted or modified by the time it returns the result.
+
+As part of its internal implementation, this program caches all stat
+and readdir calls that it makes, in order to cut down on system
+overhead.  However, this also makes it even more susceptible to races,
+especially if the cache or statCache objects are reused between glob
+calls.
+
+Users are thus advised not to use a glob result as a guarantee of
+filesystem state in the face of rapid changes.  For the vast majority
+of operations, this is never a problem.
+

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at <https://github.com/nodejitsu/node-http-proxy>. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+

+### Installation
+
+`npm install http-proxy --save`
+
+**[Back to top](#table-of-contents)**
+
+### Upgrading from 0.8.x ?
+
+Click [here](UPGRADING.md)
+
+**[Back to top](#table-of-contents)**
+
+### Core Concept
+
+A new proxy is created by calling `createProxyServer` and passing
+an `options` object as argument ([valid properties are available here](lib/http-proxy.js#L22-L50))
+
+```javascript
+var httpProxy = require('http-proxy');
+
+var proxy = httpProxy.createProxyServer(options); // See (†)
+```
+†Unless listen(..) is invoked on the object, this does not create a webserver. See below.
+
+An object will be returned with four methods:
+
+* web `req, res, [options]` (used for proxying regular HTTP(S) requests)
+* ws `req, socket, head, [options]` (used for proxying WS(S) requests)
+* listen `port` (a function that wraps the object in a webserver, for your convenience)
+* close `[callback]` (a function that closes the inner webserver and stops listening on given port)
+
+It is then possible to proxy requests by calling these functions
+
+```javascript
+http.createServer(function(req, res) {
+  proxy.web(req, res, { target: 'http://mytarget.com:8080' });
+});
+```
+
+Errors can be listened on either using the Event Emitter API
+
+```javascript
+proxy.on('error', function(e) {
+  ...
+});
+```
+
+or using the callback API
+
+```javascript
+proxy.web(req, res, { target: 'http://mytarget.com:8080' }, function(e) { ... });
+```
+
+When a request is proxied it follows two different pipelines ([available here](lib/http-proxy/passes))
+which apply transformations to both the `req` and `res` object.
+The first pipeline (incoming) is responsible for the creation and manipulation of the stream that connects your client to the target.
+The second pipeline (outgoing) is responsible for the creation and manipulation of the stream that, from your target, returns data
+to the client.
+
+**[Back to top](#table-of-contents)**
+
+### Use Cases
+
+#### Setup a basic stand-alone proxy server
+
+```js
+var http = require('http'),
+    httpProxy = require('http-proxy');
+//
+// Create your proxy server and set the target in the options.
+//
+httpProxy.createProxyServer({target:'http://localhost:9000'}).listen(8000); // See (†)
+
+//
+// Create your target server
+//
+http.createServer(function (req, res) {
+  res.writeHead(200, { 'Content-Type': 'text/plain' });
+  res.write('request successfully proxied!' + '\n' + JSON.stringify(req.headers, true, 2));
+  res.end();
+}).listen(9000);
+```
+†Invoking listen(..) triggers the creation of a web server. Otherwise, just the proxy instance is created.
+
+**[Back to top](#table-of-contents)**
+
+#### Setup a stand-alone proxy server with custom server logic
+This example shows how you can proxy a request using your own HTTP server
+and also you can put your own logic to handle the request.
+
+```js
+var http = require('http'),
+    httpProxy = require('http-proxy');
+
+//
+// Create a proxy server with custom application logic
+//
+var proxy = httpProxy.createProxyServer({});
+
+//
+// Create your custom server and just call `proxy.web()` to proxy
+// a web request to the target passed in the options
+// also you can use `proxy.ws()` to proxy a websockets request
+//
+var server = http.createServer(function(req, res) {
+  // You can define here your custom logic to handle the request
+  // and then proxy the request.
+  proxy.web(req, res, { target: 'http://127.0.0.1:5060' });
+});
+
+console.log("listening on port 5050")
+server.listen(5050);
+```
+
+**[Back to top](#table-of-contents)**
+
+#### Setup a stand-alone proxy server with proxy request header re-writing
+This example shows how you can proxy a request using your own HTTP server that
+modifies the outgoing proxy request by adding a special header.
+
+```js
+var http = require('http'),
+    httpProxy = require('http-proxy');
+
+//
+// Create a proxy server with custom application logic
+//
+var proxy = httpProxy.createProxyServer({});
+
+// To modify the proxy connection before data is sent, you can listen
+// for the 'proxyReq' event. When the event is fired, you will receive
+// the following arguments:
+// (http.ClientRequest proxyReq, http.IncomingMessage req,
+//  http.ServerResponse res, Object options). This mechanism is useful when
+// you need to modify the proxy request before the proxy connection
+// is made to the target.
+//
+proxy.on('proxyReq', function(proxyReq, req, res, options) {
+  proxyReq.setHeader('X-Special-Proxy-Header', 'foobar');
+});
+
+var server = http.createServer(function(req, res) {
+  // You can define here your custom logic to handle the request
+  // and then proxy the request.
+  proxy.web(req, res, {
+    target: 'http://127.0.0.1:5060'
+  });
+});
+
+console.log("listening on port 5050")
+server.listen(5050);
+```
+
+**[Back to top](#table-of-contents)**
+
+#### Modify a response from a proxied server
+Sometimes when you have received a HTML/XML document from the server of origin you would like to modify it before forwarding it on.
+
+[Harmon](https://github.com/No9/harmon) allows you to do this in a streaming style so as to keep the pressure on the proxy to a minimum.
+
+**[Back to top](#table-of-contents)**
+
+#### Setup a stand-alone proxy server with latency
+
+```js
+var http = require('http'),
+    httpProxy = require('http-proxy');
+
+//
+// Create a proxy server with latency
+//
+var proxy = httpProxy.createProxyServer();
+
+//
+// Create your server that makes an operation that waits a while
+// and then proxies the request
+//
+http.createServer(function (req, res) {
+  // This simulates an operation that takes 500ms to execute
+  setTimeout(function () {
+    proxy.web(req, res, {
+      target: 'http://localhost:9008'
+    });
+  }, 500);
+}).listen(8008);
+
+//
+// Create your target server
+//
+http.createServer(function (req, res) {
+  res.writeHead(200, { 'Content-Type': 'text/plain' });
+  res.write('request successfully proxied to: ' + req.url + '\n' + JSON.stringify(req.headers, true, 2));
+  res.end();
+}).listen(9008);
+```
+
+**[Back to top](#table-of-contents)**
+
+#### Using HTTPS
+You can activate the validation of a secure SSL certificate to the target connection (avoid self-signed certs), just set `secure: true` in the options.
+
+##### HTTPS -> HTTP
+
+```js
+//
+// Create the HTTPS proxy server in front of a HTTP server
+//
+httpProxy.createServer({
+  target: {
+    host: 'localhost',
+    port: 9009
+  },
+  ssl: {
+    key: fs.readFileSync('valid-ssl-key.pem', 'utf8'),
+    cert: fs.readFileSync('valid-ssl-cert.pem', 'utf8')
+  }
+}).listen(8009);
+```
+
+##### HTTPS -> HTTPS
+
+```js
+//
+// Create the proxy server listening on port 443
+//
+httpProxy.createServer({
+  ssl: {
+    key: fs.readFileSync('valid-ssl-key.pem', 'utf8'),
+    cert: fs.readFileSync('valid-ssl-cert.pem', 'utf8')
+  },
+  target: 'https://localhost:9010',
+  secure: true // Depends on your needs, could be false.
+}).listen(443);
+```
+
+##### HTTP -> HTTPS (using a PKCS12 client certificate)
+
+```js
+//
+// Create an HTTP proxy server with an HTTPS target
+//
+httpProxy.createProxyServer({
+  target: {
+    protocol: 'https:',
+    host: 'my-domain-name',
+    port: 443,
+    pfx: fs.readFileSync('path/to/certificate.p12'),
+    passphrase: 'password',
+  },
+  changeOrigin: true,
+}).listen(8000);
+```
+
+**[Back to top](#table-of-contents)**
+
+#### Proxying WebSockets
+You can activate the websocket support for the proxy using `ws:true` in the options.
+
+```js
+//
+// Create a proxy server for websockets
+//
+httpProxy.createServer({
+  target: 'ws://localhost:9014',
+  ws: true
+}).listen(8014);
+```
+
+Also you can proxy the websocket requests just calling the `ws(req, socket, head)` method.
+
+```js
+//
+// Setup our server to proxy standard HTTP requests
+//
+var proxy = new httpProxy.createProxyServer({
+  target: {
+    host: 'localhost',
+    port: 9015
+  }
+});
+var proxyServer = http.createServer(function (req, res) {
+  proxy.web(req, res);
+});
+
+//
+// Listen to the `upgrade` event and proxy the
+// WebSocket requests as well.
+//
+proxyServer.on('upgrade', function (req, socket, head) {
+  proxy.ws(req, socket, head);
+});
+
+proxyServer.listen(8015);
+```
+
+**[Back to top](#table-of-contents)**
+
+### Options
+
+`httpProxy.createProxyServer` supports the following options:
+
+*  **target**: url string to be parsed with the url module
+*  **forward**: url string to be parsed with the url module
+*  **agent**: object to be passed to http(s).request (see Node's [https agent](http://nodejs.org/api/https.html#https_class_https_agent) and [http agent](http://nodejs.org/api/http.html#http_class_http_agent) objects)
+*  **ssl**: object to be passed to https.createServer()
+*  **ws**: true/false, if you want to proxy websockets
+*  **xfwd**: true/false, adds x-forward headers
+*  **secure**: true/false, if you want to verify the SSL Certs
+*  **toProxy**: true/false, passes the absolute URL as the `path` (useful for proxying to proxies)
+*  **prependPath**: true/false, Default: true - specify whether you want to prepend the target's path to the proxy path
+*  **ignorePath**: true/false, Default: false - specify whether you want to ignore the proxy path of the incoming request (note: you will have to append / manually if required).
+*  **localAddress**: Local interface string to bind for outgoing connections
+*  **changeOrigin**: true/false, Default: false - changes the origin of the host header to the target URL
+*  **preserveHeaderKeyCase**: true/false, Default: false - specify whether you want to keep letter case of response header key
+*  **auth**: Basic authentication i.e. 'user:password' to compute an Authorization header.
+*  **hostRewrite**: rewrites the location hostname on (201/301/302/307/308) redirects.
+*  **autoRewrite**: rewrites the location host/port on (201/301/302/307/308) redirects based on requested host/port. Default: false.
+*  **protocolRewrite**: rewrites the location protocol on (201/301/302/307/308) redirects to 'http' or 'https'. Default: null.
+*  **cookieDomainRewrite**: rewrites domain of `set-cookie` headers. Possible values:
+   * `false` (default): disable cookie rewriting
+   * String: new domain, for example `cookieDomainRewrite: "new.domain"`. To remove the domain, use `cookieDomainRewrite: ""`.
+   * Object: mapping of domains to new domains, use `"*"` to match all domains.
+     For example keep one domain unchanged, rewrite one domain and remove other domains:
+     ```
+     cookieDomainRewrite: {
+       "unchanged.domain": "unchanged.domain",
+       "old.domain": "new.domain",
+       "*": ""
+     }
+     ```
+*  **cookiePathRewrite**: rewrites path of `set-cookie` headers. Possible values:
+   * `false` (default): disable cookie rewriting
+   * String: new path, for example `cookiePathRewrite: "/newPath/"`. To remove the path, use `cookiePathRewrite: ""`. To set path to root use `cookiePathRewrite: "/"`.
+   * Object: mapping of paths to new paths, use `"*"` to match all paths.
+     For example, to keep one path unchanged, rewrite one path and remove other paths:
+     ```
+     cookiePathRewrite: {
+       "/unchanged.path/": "/unchanged.path/",
+       "/old.path/": "/new.path/",
+       "*": ""
+     }
+     ```
+*  **headers**: object with extra headers to be added to target requests.
+*  **proxyTimeout**: timeout (in millis) for outgoing proxy requests
+*  **timeout**: timeout (in millis) for incoming requests
+*  **followRedirects**: true/false, Default: false - specify whether you want to follow redirects
+*  **selfHandleResponse** true/false, if set to true, none of the webOutgoing passes are called and it's your responsibility to appropriately return the response by listening and acting on the `proxyRes` event
+*  **buffer**: stream of data to send as the request body.  Maybe you have some middleware that consumes the request stream before proxying it on e.g.  If you read the body of a request into a field called 'req.rawbody' you could restream this field in the buffer option:
+
+    ```
+    'use strict';
+
+    const streamify = require('stream-array');
+    const HttpProxy = require('http-proxy');
+    const proxy = new HttpProxy();
+
+    module.exports = (req, res, next) => {
+
+      proxy.web(req, res, {
+        target: 'http://localhost:4003/',
+        buffer: streamify(req.rawBody)
+      }, next);
+
+    };
+    ```
+
+**NOTE:**
+`options.ws` and `options.ssl` are optional.
+`options.target` and `options.forward` cannot both be missing
+
+If you are using the `proxyServer.listen` method, the following options are also applicable:
+
+ *  **ssl**: object to be passed to https.createServer()
+ *  **ws**: true/false, if you want to proxy websockets
+
+
+**[Back to top](#table-of-contents)**
+
+### Listening for proxy events
+
+* `error`: The error event is emitted if the request to the target fail. **We do not do any error handling of messages passed between client and proxy, and messages passed between proxy and target, so it is recommended that you listen on errors and handle them.**
+* `proxyReq`: This event is emitted before the data is sent. It gives you a chance to alter the proxyReq request object. Applies to "web" connections
+* `proxyReqWs`: This event is emitted before the data is sent. It gives you a chance to alter the proxyReq request object. Applies to "websocket" connections
+* `proxyRes`: This event is emitted if the request to the target got a response.
+* `open`: This event is emitted once the proxy websocket was created and piped into the target websocket.
+* `close`: This event is emitted once the proxy websocket was closed.
+* (DEPRECATED) `proxySocket`: Deprecated in favor of `open`.
+
+```js
+var httpProxy = require('http-proxy');
+// Error example
+//
+// Http Proxy Server with bad target
+//
+var proxy = httpProxy.createServer({
+  target:'http://localhost:9005'
+});
+
+proxy.listen(8005);
+
+//
+// Listen for the `error` event on `proxy`.
+proxy.on('error', function (err, req, res) {
+  res.writeHead(500, {
+    'Content-Type': 'text/plain'
+  });
+
+  res.end('Something went wrong. And we are reporting a custom error message.');
+});
+
+//
+// Listen for the `proxyRes` event on `proxy`.
+//
+proxy.on('proxyRes', function (proxyRes, req, res) {
+  console.log('RAW Response from the target', JSON.stringify(proxyRes.headers, true, 2));
+});
+
+//
+// Listen for the `open` event on `proxy`.
+//
+proxy.on('open', function (proxySocket) {
+  // listen for messages coming FROM the target here
+  proxySocket.on('data', hybiParseAndLogMessage);
+});
+
+//
+// Listen for the `close` event on `proxy`.
+//
+proxy.on('close', function (res, socket, head) {
+  // view disconnected websocket connections
+  console.log('Client disconnected');
+});
+```
+
+**[Back to top](#table-of-contents)**
+
+### Shutdown
+
+* When testing or running server within another program it may be necessary to close the proxy.
+* This will stop the proxy from accepting new connections.
+
+```js
+var proxy = new httpProxy.createProxyServer({
+  target: {
+    host: 'localhost',
+    port: 1337
+  }
+});
+
+proxy.close();
+```
+
+**[Back to top](#table-of-contents)**
+
+### Miscellaneous
+
+If you want to handle your own response after receiving the `proxyRes`, you can do
+so with `selfHandleResponse`. As you can see below, if you use this option, you
+are able to intercept and read the `proxyRes` but you must also make sure to
+reply to the `res` itself otherwise the original client will never receive any
+data.
+
+### Modify response
+
+```js
+
+    var option = {
+      target: target,
+      selfHandleResponse : true
+    };
+    proxy.on('proxyRes', function (proxyRes, req, res) {
+        var body = new Buffer('');
+        proxyRes.on('data', function (data) {
+            body = Buffer.concat([body, data]);
+        });
+        proxyRes.on('end', function () {
+            body = body.toString();
+            console.log("res from proxied server:", body);
+            res.end("my response to cli");
+        });
+    });
+    proxy.web(req, res, option);
+
+
+```
+
+#### ProxyTable API
+
+A proxy table API is available through this add-on [module](https://github.com/donasaur/http-proxy-rules), which lets you define a set of rules to translate matching routes to target routes that the reverse proxy will talk to.

+var inflight = require('inflight')
+
+// some request that does some stuff
+function req(key, callback) {
+  // key is any random string.  like a url or filename or whatever.
+  //
+  // will return either a falsey value, indicating that the
+  // request for this key is already in flight, or a new callback
+  // which when called will call all callbacks passed to inflightk
+  // with the same key
+  callback = inflight(key, callback)
+
+  // If we got a falsey value back, then there's already a req going
+  if (!callback) return
+
+  // this is where you'd fetch the url or whatever
+  // callback is also once()-ified, so it can safely be assigned
+  // to multiple events etc.  First call wins.
+  setTimeout(function() {
+    callback(null, key)
+  }, 100)
+}
+
+// only assigns a single setTimeout
+// when it dings, all cbs get called
+req('foo', cb1)
+req('foo', cb2)
+req('foo', cb3)

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+   * fusion if the section is applied to an array and iteratees accept only

+   *
+   * Chaining is supported in custom builds as long as the `_#value` method is
+   * directly or indirectly included in the build.
+   *
+   * In addition to lodash methods, wrappers have `Array` and `String` methods.
+   *
+   * The wrapper `Array` methods are:
+   * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
+   *
+   * The wrapper `String` methods are:
+   * `replace` and `split`
+   *

+ * Provide `options` to indicate whether `func` should be invoked on the
+ * leading and/or trailing edge of the `wait` timeout. The `func` is invoked

+ * is invoked more than once during the `wait` timeout.

+ * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred

+     * Creates a `lodash` object which wraps `value` to enable implicit method
+     * chain sequences. Methods that operate on and return arrays, collections,
+     * and functions can be chained together. Methods that retrieve a single value
+     * or may return a primitive value will automatically end the chain sequence
+     * and return the unwrapped value. Otherwise, the value must be unwrapped
+     * with `_#value`.
+     *
+     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+     * enabled using `_.chain`.

+     * The execution of chained methods is lazy, that is, it's deferred until
+     * `_#value` is implicitly or explicitly called.
+     *
+     * Lazy evaluation allows several methods to support shortcut fusion.
+     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+     * the creation of intermediate arrays and can greatly reduce the number of
+     * iteratee executions. Sections of a chain sequence qualify for shortcut
+     * fusion if the section is applied to an array and iteratees accept only
+     * one argument. The heuristic for whether a section qualifies for shortcut
+     * fusion is subject to change.
+     *
+     * Chaining is supported in custom builds as long as the `_#value` method is
+     * directly or indirectly included in the build.

+/**
+ * Creates a `lodash` object which wraps `value` to enable implicit method
+ * chain sequences. Methods that operate on and return arrays, collections,
+ * and functions can be chained together. Methods that retrieve a single value
+ * or may return a primitive value will automatically end the chain sequence
+ * and return the unwrapped value. Otherwise, the value must be unwrapped
+ * with `_#value`.
+ *
+ * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+ * enabled using `_.chain`.
+ *
+ * The execution of chained methods is lazy, that is, it's deferred until
+ * `_#value` is implicitly or explicitly called.
+ *
+ * Lazy evaluation allows several methods to support shortcut fusion.
+ * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+ * the creation of intermediate arrays and can greatly reduce the number of
+ * iteratee executions. Sections of a chain sequence qualify for shortcut
+ * fusion if the section is applied to an array and iteratees accept only
+ * one argument. The heuristic for whether a section qualifies for shortcut
+ * fusion is subject to change.
+ *
+ * Chaining is supported in custom builds as long as the `_#value` method is
+ * directly or indirectly included in the build.
+ *
+ * In addition to lodash methods, wrappers have `Array` and `String` methods.
+ *
+ * The wrapper `Array` methods are:
+ * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
+ *
+ * The wrapper `String` methods are:
+ * `replace` and `split`
+ *
+ * The wrapper methods that support shortcut fusion are:
+ * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
+ * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
+ * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
+ *
+ * The chainable wrapper methods are:
+ * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
+ * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,

+# mime-db
+
+[![NPM Version][npm-version-image]][npm-url]
+[![NPM Downloads][npm-downloads-image]][npm-url]
+[![Node.js Version][node-image]][node-url]
+[![Build Status][travis-image]][travis-url]

+
+This is a database of all mime types.
+It consists of a single, public JSON file and does not include any logic,
+allowing it to remain as un-opinionated as possible with an API.
+It aggregates data from the following sources:
+
+- http://www.iana.org/assignments/media-types/media-types.xhtml
+- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
+- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types
+
+## Installation
+
+```bash
+npm install mime-db
+```
+
+### Database Download
+
+If you're crazy enough to use this in the browser, you can just grab the
+JSON file using [RawGit](https://rawgit.com/). It is recommended to replace
+`master` with [a release tag](https://github.com/jshttp/mime-db/tags) as the
+JSON format may change in the future.
+
+```
+https://cdn.rawgit.com/jshttp/mime-db/master/db.json
+```
+
+## Usage
+
+```js
+var db = require('mime-db');
+
+// grab data on .js files
+var data = db['application/javascript'];
+```
+
+## Data Structure
+
+The JSON file is a map lookup for lowercased mime types.
+Each mime type has the following properties:
+
+- `.source` - where the mime type is defined.
+    If not set, it's probably a custom media type.
+    - `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
+    - `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
+    - `nginx` - [nginx media types](http://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
+- `.extensions[]` - known extensions associated with this mime type.
+- `.compressible` - whether a file of this type can be gzipped.
+- `.charset` - the default charset associated with this type, if any.
+
+If unknown, every property could be `undefined`.
+
+## Contributing
+
+To edit the database, only make PRs against `src/custom.json` or
+`src/custom-suffix.json`.
+
+The `src/custom.json` file is a JSON object with the MIME type as the keys
+and the values being an object with the following keys:
+
+- `compressible` - leave out if you don't know, otherwise `true`/`false` to
+  indicate whether the data represented by the type is typically compressible.
+- `extensions` - include an array of file extensions that are associated with
+  the type.
+- `notes` - human-readable notes about the type, typically what the type is.
+- `sources` - include an array of URLs of where the MIME type and the associated
+  extensions are sourced from. This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source);
+  links to type aggregating sites and Wikipedia are _not acceptable_.
+
+To update the build, run `npm run build`.
+
+## Adding Custom Media Types
+
+The best way to get new media types included in this library is to register
+them with the IANA. The community registration procedure is outlined in
+[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
+registered with the IANA are automatically pulled into this library.

+
+The ultimate javascript content-type utility.
+
+Similar to [the `mime@1.x` module](https://www.npmjs.com/package/mime), except:
+
+- __No fallbacks.__ Instead of naively returning the first available type,
+  `mime-types` simply returns `false`, so do
+  `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
+- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
+- No `.define()` functionality
+- Bug fixes for `.lookup(path)`
+
+Otherwise, the API is compatible with `mime` 1.x.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install mime-types
+```
+
+## Adding Types
+
+All mime types are based on [mime-db](https://www.npmjs.com/package/mime-db),
+so open a PR there if you'd like to add mime types.
+
+## API
+
+```js
+var mime = require('mime-types')
+```
+
+All functions return `false` if input is invalid or not found.
+
+### mime.lookup(path)
+
+Lookup the content-type associated with a file.
+
+```js
+mime.lookup('json')             // 'application/json'
+mime.lookup('.md')              // 'text/markdown'
+mime.lookup('file.html')        // 'text/html'
+mime.lookup('folder/file.js')   // 'application/javascript'
+mime.lookup('folder/.htaccess') // false
+
+mime.lookup('cats') // false
+```
+
+### mime.contentType(type)
+
+Create a full content-type header given a content-type or extension.
+
+```js
+mime.contentType('markdown')  // 'text/x-markdown; charset=utf-8'
+mime.contentType('file.json') // 'application/json; charset=utf-8'
+
+// from a full path
+mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'
+```
+
+### mime.extension(type)
+
+Get the default extension for a content-type.
+
+```js
+mime.extension('application/octet-stream') // 'bin'
+```
+
+### mime.charset(type)
+
+Lookup the implied default charset of a content-type.
+
+```js
+mime.charset('text/markdown') // 'UTF-8'
+```
+
+### var type = mime.types[extension]
+
+A map of content-types by extension.
+
+### [extensions...] = mime.extensions[type]
+
+A map of extensions by content-type.

+# minimatch
+
+A minimal matching utility.
+
+[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.svg)](http://travis-ci.org/isaacs/minimatch)
+
+
+This is the matching library used internally by npm.
+
+It works by converting glob expressions into JavaScript `RegExp`
+objects.
+
+## Usage
+
+```javascript
+var minimatch = require("minimatch")
+
+minimatch("bar.foo", "*.foo") // true!
+minimatch("bar.foo", "*.bar") // false!
+minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
+```
+
+## Features
+
+Supports these glob features:
+
+* Brace Expansion
+* Extended glob matching
+* "Globstar" `**` matching
+
+See:
+
+* `man sh`
+* `man bash`
+* `man 3 fnmatch`
+* `man 5 gitignore`
+
+## Minimatch Class
+
+Create a minimatch object by instantiating the `minimatch.Minimatch` class.
+
+```javascript
+var Minimatch = require("minimatch").Minimatch
+var mm = new Minimatch(pattern, options)
+```
+
+### Properties
+
+* `pattern` The original pattern the minimatch object represents.
+* `options` The options supplied to the constructor.
+* `set` A 2-dimensional array of regexp or string expressions.
+  Each row in the
+  array corresponds to a brace-expanded pattern.  Each item in the row
+  corresponds to a single path-part.  For example, the pattern
+  `{a,b/c}/d` would expand to a set of patterns like:
+
+        [ [ a, d ]
+        , [ b, c, d ] ]
+
+    If a portion of the pattern doesn't have any "magic" in it
+    (that is, it's something like `"foo"` rather than `fo*o?`), then it
+    will be left as a string rather than converted to a regular
+    expression.
+
+* `regexp` Created by the `makeRe` method.  A single regular expression
+  expressing the entire pattern.  This is useful in cases where you wish
+  to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
+* `negate` True if the pattern is negated.
+* `comment` True if the pattern is a comment.
+* `empty` True if the pattern is `""`.
+
+### Methods
+
+* `makeRe` Generate the `regexp` member if necessary, and return it.
+  Will return `false` if the pattern is invalid.
+* `match(fname)` Return true if the filename matches the pattern, or
+  false otherwise.
+* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
+  filename, and match it against a single row in the `regExpSet`.  This
+  method is mainly for internal use, but is exposed so that it can be
+  used by a glob-walker that needs to avoid excessive filesystem calls.
+
+All other methods are internal, and will be called as necessary.
+
+### minimatch(path, pattern, options)
+
+Main export.  Tests a path against the pattern using the options.
+
+```javascript
+var isJS = minimatch(file, "*.js", { matchBase: true })
+```
+
+### minimatch.filter(pattern, options)
+
+Returns a function that tests its
+supplied argument, suitable for use with `Array.filter`.  Example:
+
+```javascript
+var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
+```
+
+### minimatch.match(list, pattern, options)
+
+Match against the list of
+files, in the style of fnmatch or glob.  If nothing is matched, and
+options.nonull is set, then return a list containing the pattern itself.
+
+```javascript
+var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
+```
+
+### minimatch.makeRe(pattern, options)
+
+Make a regular expression object from the pattern.
+
+## Options
+
+All options are `false` by default.
+
+### debug
+
+Dump a ton of stuff to stderr.
+
+### nobrace
+
+Do not expand `{a,b}` and `{1..3}` brace sets.
+
+### noglobstar
+
+Disable `**` matching against multiple folder names.
+
+### dot
+
+Allow patterns to match filenames starting with a period, even if
+the pattern does not explicitly have a period in that spot.
+
+Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
+is set.
+
+### noext
+
+Disable "extglob" style patterns like `+(a|b)`.
+
+### nocase
+
+Perform a case-insensitive match.
+
+### nonull
+
+When a match is not found by `minimatch.match`, return a list containing
+the pattern itself if this option is set.  When not set, an empty list
+is returned if there are no matches.
+
+### matchBase
+
+If set, then patterns without slashes will be matched
+against the basename of the path if it contains slashes.  For example,
+`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
+
+### nocomment
+
+Suppress the behavior of treating `#` at the start of a pattern as a
+comment.
+
+### nonegate
+
+Suppress the behavior of treating a leading `!` character as negation.
+
+### flipNegate
+
+Returns from negate expressions the same as if they were not negated.
+(Ie, true on a hit, false on a miss.)
+
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between minimatch and other
+implementations, and are intentional.
+
+If the pattern starts with a `!` character, then it is negated.  Set the
+`nonegate` flag to suppress this behavior, and treat leading `!`
+characters normally.  This is perhaps relevant if you wish to start the
+pattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`
+characters at the start of a pattern will negate the pattern multiple
+times.
+
+If a pattern starts with `#`, then it is treated as a comment, and
+will not match anything.  Use `\#` to match a literal `#` at the
+start of a line, or set the `nocomment` flag to suppress this behavior.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.1, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then minimatch.match returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
+
+[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.dir(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a string or array of strings to always treat as booleans
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values

+# mkdirp
+
+Like `mkdir -p`, but in node.js!
+
+[![build status](https://secure.travis-ci.org/substack/node-mkdirp.png)](http://travis-ci.org/substack/node-mkdirp)
+
+# example
+
+## pow.js
+
+```js
+var mkdirp = require('mkdirp');
+    
+mkdirp('/tmp/foo/bar/baz', function (err) {
+    if (err) console.error(err)
+    else console.log('pow!')
+});
+```
+
+Output
+
+```
+pow!
+```
+
+And now /tmp/foo/bar/baz exists, huzzah!
+
+# methods
+
+```js
+var mkdirp = require('mkdirp');
+```
+
+## mkdirp(dir, opts, cb)
+
+Create a new directory and any necessary subdirectories at `dir` with octal
+permission string `opts.mode`. If `opts` is a non-object, it will be treated as
+the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777 & (~process.umask())`.
+
+`cb(err, made)` fires with the error or the first directory `made`
+that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdir(path, mode, cb)` and
+`opts.fs.stat(path, cb)`.
+
+## mkdirp.sync(dir, opts)
+
+Synchronously create a new directory and any necessary subdirectories at `dir`
+with octal permission string `opts.mode`. If `opts` is a non-object, it will be
+treated as the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777 & (~process.umask())`.
+
+Returns the first directory that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdirSync(path, mode)` and
+`opts.fs.statSync(path)`.
+
+# usage
+
+This package also ships with a `mkdirp` command.
+
+```
+usage: mkdirp [DIR1,DIR2..] {OPTIONS}
+
+  Create each supplied directory including any necessary parent directories that
+  don't yet exist.
+  
+  If the directory already exists, do nothing.
+
+OPTIONS are:
+
+  -m, --mode   If a directory needs to be created, set the mode as an octal
+               permission string.
+
+```
+
+# install
+
+With [npm](http://npmjs.org) do:
+
+```
+npm install mkdirp
+```
+
+to get the library, or
+
+```
+npm install -g mkdirp
+```
+
+to get the command.

+
+### 2.8.0 [See changelog](https://gist.github.com/ichernev/ac3899324a5fa6c8c9b4)
+
+- Release July 31, 2014
+
+* incompatible changes
+    * [#1761](https://github.com/moment/moment/issues/1761): moments created without a language are no longer following the global language, in case it changes. Only newly created moments take the global language by default. In case you're affected by this, wait, comment on [#1797](https://github.com/moment/moment/issues/1797) and wait for a proper reimplementation
+    * [#1642](https://github.com/moment/moment/issues/1642): 45 days is no longer "a month" according to humanize, cutoffs for month, and year have changed. Hopefully your code does not depend on a particular answer from humanize (which it shouldn't anyway)
+    * [#1784](https://github.com/moment/moment/issues/1784): if you use the human readable English datetime format in a weird way (like storing them in a database) that would break when the format changes you're at risk.
+
+* deprecations (old behavior will be dropped in 3.0)
+    * [#1761](https://github.com/moment/moment/issues/1761) `lang` is renamed to `locale`, `langData` -> `localeData`. Also there is now `defineLocale` that should be used when creating new locales
+    * [#1763](https://github.com/moment/moment/issues/1763) `add(unit, value)` and `subtract(unit, value)` are now deprecated. Use `add(value, unit)` and `subtract(value, unit)` instead.
+    * [#1759](https://github.com/moment/moment/issues/1759) rename `duration.toIsoString` to `duration.toISOString`. The js standard library and moment's `toISOString` follow that convention.
+
+* new locales
+    * [#1789](https://github.com/moment/moment/issues/1789) Tibetan (bo)
+    * [#1786](https://github.com/moment/moment/issues/1786) Africaans (af)

+
+A lightweight JavaScript date library for parsing, validating, manipulating, and formatting dates.
+
+**[Documentation](http://momentjs.com/docs/)**
+
+## Port to ECMAScript 6 (version 2.10.0)
+
+Moment 2.10.0 does not bring any new features, but the code is now written in
+ECMAScript 6 modules and placed inside `src/`. Previously `moment.js`, `locale/*.js` and
+`test/moment/*.js`, `test/locale/*.js` contained the source of the project. Now
+the source is in `src/`, temporary build (ECMAScript 5) files are placed under
+`build/umd/` (for running tests during development), and the `moment.js` and
+`locale/*.js` files are updated only on release.
+
+If you want to use a particular revision of the code, make sure to run
+`grunt transpile update-index`, so `moment.js` and `locales/*.js` are synced
+with `src/*`. We might place that in a commit hook in the future.
+
+## Upgrading to 2.0.0
+
+There are a number of small backwards incompatible changes with version 2.0.0. [See the full descriptions here](https://gist.github.com/timrwood/e72f2eef320ed9e37c51#backwards-incompatible-changes)
+
+ * Changed language ordinal method to return the number + ordinal instead of just the ordinal.
+
+ * Changed two digit year parsing cutoff to match strptime.
+
+ * Removed `moment#sod` and `moment#eod` in favor of `moment#startOf` and `moment#endOf`.
+
+ * Removed `moment.humanizeDuration()` in favor of `moment.duration().humanize()`.
+
+ * Removed the lang data objects from the top level namespace.
+
+ * Duplicate `Date` passed to `moment()` instead of referencing it.

+# ms
+
+[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
+[![Slack Channel](http://zeit-slackin.now.sh/badge.svg)](https://zeit.chat/)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days')  // 172800000
+ms('1d')      // 86400000
+ms('10h')     // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h')      // 7200000
+ms('1m')      // 60000
+ms('5s')      // 5000
+ms('1y')      // 31557600000
+ms('100')     // 100
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
+
+## Caught a bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+------
+
+```js
+var mv = require('mv');
+
+mv('source/file', 'dest/file', function(err) {
+  // done. it tried fs.rename first, and then falls back to
+  // piping the source file to the dest file and then unlinking
+  // the source file.
+});
+```
+
+Another example:
+
+```js
+mv('source/dir', 'dest/a/b/c/dir', {mkdirp: true}, function(err) {
+  // done. it first created all the necessary directories, and then
+  // tried fs.rename, then falls back to using ncp to copy the dir
+  // to dest and then rimraf to remove the source dir
+});
+```
+
+Another example:
+
+```js
+mv('source/file', 'dest/file', {clobber: false}, function(err) {
+  // done. If 'dest/file' exists, an error is returned
+  // with err.code === 'EEXIST'.
+});
+```

+Native Abstractions for Node.js
+===============================
+
+**A header file filled with macro and utility goodness for making add-on development for Node.js easier across versions 0.8, 0.10, 0.12, 1, 2, 3, 4, 5, 6, 7, 8 and 9.**
+
+***Current version: 2.10.0***
+
+*(See [CHANGELOG.md](https://github.com/nodejs/nan/blob/master/CHANGELOG.md) for complete ChangeLog)*

+
+Thanks to the crazy changes in V8 (and some in Node core), keeping native addons compiling happily across versions, particularly 0.10 to 0.12 to 4.0, is a minor nightmare. The goal of this project is to store all logic necessary to develop native Node.js addons without having to inspect `NODE_MODULE_VERSION` and get yourself into a macro-tangle.
+
+This project also contains some helper utilities that make addon development a bit more pleasant.

+## News & Updates
+
+<a name="usage"></a>
+
+## Usage
+
+Simply add **NAN** as a dependency in the *package.json* of your Node addon:
+
+``` bash
+$ npm install --save nan
+```
+
+Pull in the path to **NAN** in your *binding.gyp* so that you can use `#include <nan.h>` in your *.cpp* files:
+
+``` python
+"include_dirs" : [
+    "<!(node -e \"require('nan')\")"
+]
+```
+
+This works like a `-I<path-to-NAN>` when compiling your addon.
+
+<a name="example"></a>
+
+## Example
+
+Just getting started with Nan? Take a look at the **[Node Add-on Examples](https://github.com/nodejs/node-addon-examples)**.
+
+Refer to a [quick-start **Nan** Boilerplate](https://github.com/fcanas/node-native-boilerplate) for a ready-to-go project that utilizes basic Nan functionality.

+
+### JavaScript-accessible methods
+
+A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information.
+
+In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

+
+### Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="doc/scopes.md#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="doc/scopes.md#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection).
+
+### Persistent references
+
+An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
+
+Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://developers.google.com/v8/embed#handles).
+
+### New
+
+NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8.

+ - <a href="doc/new.md#api_nan_false"><b><code>Nan::False()</code></b></a>
+ - <a href="doc/new.md#api_nan_empty_string"><b><code>Nan::EmptyString()</code></b></a>
+
+
+### Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.
+
+ - <a href="doc/converters.md#api_nan_to"><b><code>Nan::To()</code></b></a>
+
+### Maybe Types
+
+The `Nan::MaybeLocal` and `Nan::Maybe` types are monads that encapsulate `v8::Local` handles that _may be empty_.

+### Script
+
+NAN provides a `v8::Script` helpers as the API has changed over the supported versions of V8.
+
+ - <a href="doc/script.md#api_nan_compile_script"><b><code>Nan::CompileScript()</code></b></a>
+ - <a href="doc/script.md#api_nan_run_script"><b><code>Nan::RunScript()</code></b></a>
+
+
+### JSON
+
+The _JSON_ object provides the c++ versions of the methods offered by the `JSON` object in javascript. V8 exposes these methods via the `v8::JSON` object.
+
+ - <a href="doc/json.md#api_nan_json_parse"><b><code>Nan::JSON.Parse</code></b></a>
+ - <a href="doc/json.md#api_nan_json_stringify"><b><code>Nan::JSON.Stringify</code></b></a>
+
+Refer to the V8 JSON object in the [V8 documentation](https://v8docs.nodesource.com/node-7.4/da/d6f/classv8_1_1_j_s_o_n.html) for more information about these methods and their arguments.
+
+### Errors
+
+NAN includes helpers for creating, throwing and catching Errors as much of this functionality varies across the supported versions of V8 and must be abstracted.
+
+Note that an Error object is simply a specialized form of `v8::Value`.
+
+Also consult the V8 Embedders Guide section on [Exceptions](https://developers.google.com/v8/embed#exceptions) for more information.

+
+
+### Buffers
+
+NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.

+ - <a href="doc/buffers.md#api_nan_free_callback"><b><code>Nan::FreeCallback()</code></b></a>
+
+### Nan::Callback
+
+`Nan::Callback` makes it easier to use `v8::Function` handles as callbacks. A class that wraps a `v8::Function` handle, protecting it from garbage collection and making it particularly useful for storage and use across asynchronous execution.
+
+ - <a href="doc/callback.md#api_nan_callback"><b><code>Nan::Callback</code></b></a>
+
+### Asynchronous work helpers
+
+`Nan::AsyncWorker`, `Nan::AsyncProgressWorker` and `Nan::AsyncProgressQueueWorker` are helper classes that make working with asynchronous code easier.

+
+### Strings & Bytes
+
+Miscellaneous string & byte encoding and decoding functionality provided for compatibility across supported versions of V8 and Node. Implemented by NAN to ensure that all encoding types are supported, even for older versions of Node where they are missing.

+ - <a href="doc/object_wrappers.md#api_nan_object_wrap"><b><code>Nan::ObjectWrap</code></b></a>
+
+
+### V8 internals
+
+The hooks to access V8 internals—including GC and statistics—are different across the supported versions of V8, therefore NAN provides its own hooks that call the appropriate V8 methods.

+## Known issues
+
+### Compiling against Node.js 0.12 on OSX
+
+With new enough compilers available on OSX, the versions of V8 headers corresponding to Node.js 0.12
+do not compile anymore. The error looks something like:
+
+```
+❯   CXX(target) Release/obj.target/accessors/cpp/accessors.o
+In file included from ../cpp/accessors.cpp:9:
+In file included from ../../nan.h:51:
+In file included from /Users/ofrobots/.node-gyp/0.12.18/include/node/node.h:61:
+/Users/ofrobots/.node-gyp/0.12.18/include/node/v8.h:5800:54: error: 'CreateHandle' is a protected member of 'v8::HandleScope'
+  return Handle<T>(reinterpret_cast<T*>(HandleScope::CreateHandle(
+                                        ~~~~~~~~~~~~~^~~~~~~~~~~~
+```
+
+This can be worked around by patching your local versions of v8.h corresponding to Node 0.12 to make
+`v8::Handle` a friend of `v8::HandleScope`. Since neither Node.js not V8 support this release line anymore
+this patch cannot be released by either project in an official release.
+
+For this reason, we do not test against Node.js 0.12 on OSX in this project's CI. If you need to support
+that configuration, you will need to either get an older compiler, or apply a source patch to the version
+of V8 headers as a workaround.

+## Governance & Contributing
+
+NAN is governed by the [Node.js Addon API Working Group](https://github.com/nodejs/CTC/blob/master/WORKING_GROUPS.md#addon-api)
+
+### Addon API Working Group (WG)
+
+The NAN project is jointly governed by a Working Group which is responsible for high-level guidance of the project.
+
+Members of the WG are also known as Collaborators, there is no distinction between the two, unlike other Node.js projects.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project [README.md](./README.md#collaborators).
+
+Individuals making significant and valuable contributions are made members of the WG and given commit-access to the project. These individuals are identified by the WG and their addition to the WG is discussed via GitHub and requires unanimous consensus amongst those WG members participating in the discussion with a quorum of 50% of WG members required for acceptance of the vote.
+
+_Note:_ If you make a significant contribution and are not considered for commit-access log an issue or contact a WG member directly.
+
+For the current list of WG members / Collaborators, see the project [README.md](./README.md#collaborators).
+
+### Consensus Seeking Process
+
+The WG follows a [Consensus Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making) decision making model.
+
+Modifications of the contents of the NAN repository are made on a collaborative basis. Anybody with a GitHub account may propose a modification via pull request and it will be considered by the WG. All pull requests must be reviewed and accepted by a WG member with sufficient expertise who is able to take full responsibility for the change. In the case of pull requests proposed by an existing WG member, an additional WG member is required for sign-off. Consensus should be sought if additional WG members participate and there is disagreement around a particular modification.
+
+If a change proposal cannot reach a consensus, a WG member can call for a vote amongst the members of the WG. Simple majority wins.

+## Asynchronous work helpers
+
+`Nan::AsyncWorker`, `Nan::AsyncProgressWorker` and `Nan::AsyncProgressQueueWorker` are helper classes that make working with asynchronous code easier.

+### Nan::AsyncWorker
+
+`Nan::AsyncWorker` is an _abstract_ class that you can subclass to have much of the annoying asynchronous queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the asynchronous work is in progress.
+
+This class internally handles the details of creating an [`AsyncResource`][AsyncResource], and running the callback in the
+correct async context. To be able to identify the async resources created by this class in async-hooks, provide a
+`resource_name` to the constructor. It is recommended that the module name be used as a prefix to the `resource_name` to avoid
+collisions in the names. For more details see [`AsyncResource`][AsyncResource] documentation.  The `resource_name` needs to stay valid for the lifetime of the worker instance.
+
+Definition:
+
+```c++
+class AsyncWorker {
+ public:
+  explicit AsyncWorker(Callback *callback_, const char* resource_name = "nan:AsyncWorker");
+
+  virtual ~AsyncWorker();
+
+  virtual void WorkComplete();
+
+  void SaveToPersistent(const char *key, const v8::Local<v8::Value> &value);
+
+  void SaveToPersistent(const v8::Local<v8::String> &key,
+                        const v8::Local<v8::Value> &value);
+
+  void SaveToPersistent(uint32_t index,
+                        const v8::Local<v8::Value> &value);
+
+  v8::Local<v8::Value> GetFromPersistent(const char *key) const;
+
+  v8::Local<v8::Value> GetFromPersistent(const v8::Local<v8::String> &key) const;
+
+  v8::Local<v8::Value> GetFromPersistent(uint32_t index) const;

+
+  void SetErrorMessage(const char *msg);
+
+  const char* ErrorMessage();
+};
+```
+
+<a name="api_nan_async_progress_worker"></a>
+### Nan::AsyncProgressWorkerBase &amp; Nan::AsyncProgressWorker
+
+`Nan::AsyncProgressWorkerBase` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
+
+Previously the definiton of `Nan::AsyncProgressWorker` only allowed sending `const char` data. Now extending `Nan::AsyncProgressWorker` will yield an instance of the implicit `Nan::AsyncProgressWorkerBase` template with type `<char>` for compatibility.
+
+`Nan::AsyncProgressWorkerBase` &amp; `Nan::AsyncProgressWorker` is intended for best-effort delivery of nonessential progress messages, e.g. a progress bar.  The last event sent before the main thread is woken will be delivered.
+
+Definition:
+
+```c++
+template<class T>
+class AsyncProgressWorkerBase<T> : public AsyncWorker {
+ public:
+  explicit AsyncProgressWorkerBase(Callback *callback_, const char* resource_name = ...);
+
+  virtual ~AsyncProgressWorkerBase();
+
+  void WorkProgress();
+
+  class ExecutionProgress {
+   public:
+    void Signal() const;
+    void Send(const T* data, size_t count) const;
+  };
+
+  virtual void Execute(const ExecutionProgress& progress) = 0;
+
+  virtual void HandleProgressCallback(const T *data, size_t count) = 0;
+
+  virtual void Destroy();
+};
+
+typedef AsyncProgressWorkerBase<T> AsyncProgressWorker;
+```

+<a name="api_nan_async_progress_queue_worker"></a>
+### Nan::AsyncProgressQueueWorker
+
+`Nan::AsyncProgressQueueWorker` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
+
+`Nan::AsyncProgressQueueWorker` behaves exactly the same as `Nan::AsyncProgressWorker`, except all events are queued and delivered to the main thread.
+
+Definition:
+
+```c++
+template<class T>
+class AsyncProgressQueueWorker<T> : public AsyncWorker {
+ public:
+  explicit AsyncProgressQueueWorker(Callback *callback_, const char* resource_name = "nan:AsyncProgressQueueWorker");
+
+  virtual ~AsyncProgressQueueWorker();
+
+  void WorkProgress();
+
+  class ExecutionProgress {
+   public:
+    void Send(const T* data, size_t count) const;
+  };
+
+  virtual void Execute(const ExecutionProgress& progress) = 0;
+
+  virtual void HandleProgressCallback(const T *data, size_t count) = 0;
+
+  virtual void Destroy();
+};
+```
+
+<a name="api_nan_async_queue_worker"></a>
+### Nan::AsyncQueueWorker
+
+`Nan::AsyncQueueWorker` will run a `Nan::AsyncWorker` asynchronously via libuv. Both the `execute` and `after_work` steps are taken care of for you. Most of the logic for this is embedded in `Nan::AsyncWorker`.

+## Buffers
+
+NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.

+ - <a href="#api_nan_free_callback"><b><code>Nan::FreeCallback()</code></b></a>
+
+<a name="api_nan_new_buffer"></a>
+### Nan::NewBuffer()
+
+Allocate a new `node::Buffer` object with the specified size and optional data. Calls `node::Buffer::New()`.
+
+Note that when creating a `Buffer` using `Nan::NewBuffer()` and an existing `char*`, it is assumed that the ownership of the pointer is being transferred to the new `Buffer` for management.
+When a `node::Buffer` instance is garbage collected and a `FreeCallback` has not been specified, `data` will be disposed of via a call to `free()`.
+You _must not_ free the memory space manually once you have created a `Buffer` in this way.

+### Nan::CopyBuffer()
+
+Similar to [`Nan::NewBuffer()`](#api_nan_new_buffer) except that an implicit memcpy will occur within Node. Calls `node::Buffer::Copy()`.
+
+Management of the `char*` is left to the user, you should manually free the memory space if necessary as the new `Buffer` will have its own copy.

+### Nan::FreeCallback()
+
+A free callback that can be provided to [`Nan::NewBuffer()`](#api_nan_new_buffer).
+The supplied callback will be invoked when the `Buffer` undergoes garbage collection.
+
+Signature:
+
+```c++
+typedef void (*FreeCallback)(char *data, void *hint);

+## Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.

+## JSON
+
+The _JSON_ object provides the c++ versions of the methods offered by the `JSON` object in javascript. V8 exposes these methods via the `v8::JSON` object.
+
+ - <a href="#api_nan_json_parse"><b><code>Nan::JSON.Parse</code></b></a>
+ - <a href="#api_nan_json_stringify"><b><code>Nan::JSON.Stringify</code></b></a>
+
+Refer to the V8 JSON object in the [V8 documentation](https://v8docs.nodesource.com/node-7.4/da/d6f/classv8_1_1_j_s_o_n.html) for more information about these methods and their arguments.

+
+A simple wrapper around [`v8::JSON::Parse`](https://v8docs.nodesource.com/node-7.4/da/d6f/classv8_1_1_j_s_o_n.html#a936310d2540fb630ed37d3ee3ffe4504).
+
+Definition:
+
+```c++
+Nan::MaybeLocal<v8::Value> Nan::JSON::Parse(v8::Local<v8::String> json_string);
+```
+
+Use `JSON.Parse(json_string)` to parse a string into a `v8::Value`.
+
+Example:
+
+```c++
+v8::Local<v8::String> json_string = Nan::New("{ \"JSON\": \"object\" }").ToLocalChecked();
+
+Nan::JSON NanJSON;
+Nan::MaybeLocal<v8::Value> result = NanJSON.Parse(json_string);

+### Nan::MaybeLocal
+
+A `Nan::MaybeLocal<T>` is a wrapper around [`v8::Local<T>`](https://v8docs.nodesource.com/io.js-3.3/de/deb/classv8_1_1_local.html) that enforces a check that determines whether the `v8::Local<T>` is empty before it can be used.
+
+If an API method returns a `Nan::MaybeLocal`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, an empty `Nan::MaybeLocal` is returned.
+
+Definition:
+
+```c++
+template<typename T> class Nan::MaybeLocal {
+ public:
+  MaybeLocal();
+
+  template<typename S> MaybeLocal(v8::Local<S> that);
+
+  bool IsEmpty() const;
+
+  template<typename S> bool ToLocal(v8::Local<S> *out);
+
+  // Will crash if the MaybeLocal<> is empty.
+  v8::Local<T> ToLocalChecked();
+
+  template<typename S> v8::Local<S> FromMaybe(v8::Local<S> default_value) const;
+};
+```
+
+See the documentation for [`v8::MaybeLocal`](https://v8docs.nodesource.com/io.js-3.3/d8/d7d/classv8_1_1_maybe_local.html) for further details.
+
+<a name="api_nan_maybe"></a>
+### Nan::Maybe
+
+A simple `Nan::Maybe` type, representing an object which may or may not have a value, see https://hackage.haskell.org/package/base/docs/Data-Maybe.html.
+
+If an API method returns a `Nan::Maybe<>`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, a "Nothing" value is returned.
+
+Definition:
+
+```c++
+template<typename T> class Nan::Maybe {
+ public:
+  bool IsNothing() const;
+  bool IsJust() const;
+
+  // Will crash if the Maybe<> is nothing.
+  T FromJust();
+
+  T FromMaybe(const T& default_value);
+
+  bool operator==(const Maybe &other);
+
+  bool operator!=(const Maybe &other);
+};
+```
+
+See the documentation for [`v8::Maybe`](https://v8docs.nodesource.com/io.js-3.3/d9/d4b/classv8_1_1_maybe.html) for further details.

+## JavaScript-accessible methods
+
+A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information.
+
+In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

+### Nan::FunctionCallbackInfo
+
+`Nan::FunctionCallbackInfo` should be used in place of [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/node-8.0/dd/d0d/classv8_1_1_function_callback_info.html), even with older versions of Node where `v8::FunctionCallbackInfo` does not exist.
+
+Definition:
+
+```c++
+template<typename T> class FunctionCallbackInfo {
+ public:
+  ReturnValue<T> GetReturnValue() const;
+  v8::Local<v8::Function> Callee();
+  v8::Local<v8::Value> Data();
+  v8::Local<v8::Object> Holder();
+  bool IsConstructCall();
+  int Length() const;
+  v8::Local<v8::Value> operator[](int i) const;
+  v8::Local<v8::Object> This() const;
+  v8::Isolate *GetIsolate() const;
+};
+```
+
+See the [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/node-8.0/dd/d0d/classv8_1_1_function_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from methods.
+
+<a name="api_nan_property_callback_info"></a>
+### Nan::PropertyCallbackInfo
+
+`Nan::PropertyCallbackInfo` should be used in place of [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/node-8.0/d7/dc5/classv8_1_1_property_callback_info.html), even with older versions of Node where `v8::PropertyCallbackInfo` does not exist.
+
+Definition:
+
+```c++
+template<typename T> class PropertyCallbackInfo : public PropertyCallbackInfoBase<T> {
+ public:
+  ReturnValue<T> GetReturnValue() const;
+  v8::Isolate* GetIsolate() const;
+  v8::Local<v8::Value> Data() const;
+  v8::Local<v8::Object> This() const;
+  v8::Local<v8::Object> Holder() const;
+};
+```
+
+See the [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/node-8.0/d7/dc5/classv8_1_1_property_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from property accessor methods.
+
+<a name="api_nan_return_value"></a>
+### Nan::ReturnValue
+
+`Nan::ReturnValue` is used in place of [`v8::ReturnValue`](https://v8docs.nodesource.com/node-8.0/da/da7/classv8_1_1_return_value.html) on both [`Nan::FunctionCallbackInfo`](#api_nan_function_callback_info) and [`Nan::PropertyCallbackInfo`](#api_nan_property_callback_info) as the return type of `GetReturnValue()`.
+
+Example usage:
+
+```c++
+void EmptyArray(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  info.GetReturnValue().Set(Nan::New<v8::Array>());
+}
+```
+
+Definition:
+
+```c++
+template<typename T> class ReturnValue {
+ public:
+  // Handle setters
+  template <typename S> void Set(const v8::Local<S> &handle);
+  template <typename S> void Set(const Nan::Global<S> &handle);
+
+  // Fast primitive setters
+  void Set(bool value);
+  void Set(double i);
+  void Set(int32_t i);
+  void Set(uint32_t i);
+
+  // Fast JS primitive setters
+  void SetNull();
+  void SetUndefined();
+  void SetEmptyString();
+
+  // Convenience getter for isolate
+  v8::Isolate *GetIsolate() const;
+};
+```
+
+See the documentation on [`v8::ReturnValue`](https://v8docs.nodesource.com/node-8.0/da/da7/classv8_1_1_return_value.html) for further information on this.
+
+<a name="api_nan_method"></a>
+### Method declaration
+
+JavaScript-accessible methods should be declared with the following signature to form a `Nan::FunctionCallback`:
+
+```c++
+typedef void(*FunctionCallback)(const FunctionCallbackInfo<v8::Value>&);
+```
+
+Example:
+
+```c++
+void MethodName(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  ...
+}
+```
+
+You do not need to declare a new `HandleScope` within a method as one is implicitly created for you.
+
+**Example usage**
+
+```c++
+// .h:
+class Foo : public Nan::ObjectWrap {
+  ...
+
+  static void Bar(const Nan::FunctionCallbackInfo<v8::Value>& info);
+  static void Baz(const Nan::FunctionCallbackInfo<v8::Value>& info);
+}
+
+
+// .cc:
+void Foo::Bar(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  ...
+}
+
+void Foo::Baz(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  ...
+}
+```
+
+A helper macro `NAN_METHOD(methodname)` exists, compatible with NAN v1 method declarations.
+
+**Example usage with `NAN_METHOD(methodname)`**
+
+```c++
+// .h:
+class Foo : public Nan::ObjectWrap {
+  ...
+
+  static NAN_METHOD(Bar);
+  static NAN_METHOD(Baz);
+}
+
+
+// .cc:
+NAN_METHOD(Foo::Bar) {
+  ...
+}
+
+NAN_METHOD(Foo::Baz) {
+  ...
+}
+```
+
+Use [`Nan::SetPrototypeMethod`](#api_nan_set_prototype_method) to attach a method to a JavaScript function prototype or [`Nan::SetMethod`](#api_nan_set_method) to attach a method directly on a JavaScript object.
+
+<a name="api_nan_getter"></a>
+### Getter declaration
+
+JavaScript-accessible getters should be declared with the following signature to form a `Nan::GetterCallback`:
+
+```c++
+typedef void(*GetterCallback)(v8::Local<v8::String>,
+                              const PropertyCallbackInfo<v8::Value>&);
+```
+
+Example:
+
+```c++
+void GetterName(v8::Local<v8::String> property,
+                const Nan::PropertyCallbackInfo<v8::Value>& info) {
+  ...
+}
+```
+
+You do not need to declare a new `HandleScope` within a getter as one is implicitly created for you.
+
+A helper macro `NAN_GETTER(methodname)` exists, compatible with NAN v1 method declarations.
+
+Also see the V8 Embedders Guide documentation on [Accessors](https://developers.google.com/v8/embed#accesssors).
+
+<a name="api_nan_setter"></a>
+### Setter declaration
+
+JavaScript-accessible setters should be declared with the following signature to form a <b><code>Nan::SetterCallback</code></b>:
+
+```c++
+typedef void(*SetterCallback)(v8::Local<v8::String>,
+                              v8::Local<v8::Value>,
+                              const PropertyCallbackInfo<void>&);
+```
+
+Example:
+

+### Nan::New()
+
+`Nan::New()` should be used to instantiate new JavaScript objects.
+
+Refer to the specific V8 type in the [V8 documentation](https://v8docs.nodesource.com/io.js-3.3/d1/d83/classv8_1_1_data.html) for information on the types of arguments required for instantiation.
+
+Signatures:
+
+Return types are mostly omitted from the signatures for simplicity. In most cases the type will be contained within a `v8::Local<T>`. The following types will be contained within a `Nan::MaybeLocal<T>`: `v8::String`, `v8::Date`, `v8::RegExp`, `v8::Script`, `v8::UnboundScript`.
+
+Empty objects:
+
+```c++
+Nan::New<T>();
+```
+
+Generic single and multiple-argument:
+
+```c++

+
+<a name="api_nan_asyncresource"></a>
+### Nan::AsyncResource
+
+This class is analogous to the `AsyncResource` JavaScript class exposed by Node's [async_hooks][] API.
+
+When calling back into JavaScript asynchornously, special care must be taken to ensure that the runtime can properly track
+async hops. `Nan::AsyncResource` is a class that provides an RAII wrapper around `node::EmitAsyncInit`, `node::EmitAsyncDestroy`,
+and `node::MakeCallback`. Using this mechanism to call back into JavaScript, as opposed to `Nan::MakeCallback` or
+`v8::Function::Call` ensures that the callback is executed in the correct async context. This ensures that async mechanisms
+such as domains and [async_hooks][] function correctly.
+
+Definition:
+
+```c++
+class AsyncResource {
+ public:
+  AsyncResource(v8::Local<v8::String> name,
+                v8::Local<v8::Object> resource = New<v8::Object>());
+  AsyncResource(const char* name,
+                v8::Local<v8::Object> resource = New<v8::Object>());
+  ~AsyncResource();
+
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            v8::Local<v8::Function> func,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            v8::Local<v8::String> symbol,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            const char* method,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+};
+```
+
+* `name`: Identifier for the kind of resource that is being provided for diagnostics information exposed by the [async_hooks][]
+  API. This will be passed to the possible `init` hook as the `type`. To avoid name collisions with other modules we recommend
+  that the name include the name of the owning module as a prefix. For example `mysql` module could use something like
+  `mysql:batch-db-query-resource`.
+* `resource`: An optional object associated with the async work that will be passed to the possible [async_hooks][]
+  `init` hook. If this parameter is omitted, or an empty handle is provided, this object will be created automatically.
+* When calling JS on behalf of this resource, one can use `runInAsyncScope`. This will ensure that the callback runs in the
+  correct async execution context.
+* `AsyncDestroy` is automatically called when an AsyncResource object is destroyed.
+
+For more details, see the Node [async_hooks][] documentation. You might also want to take a look at the documentation for the
+[N-API counterpart][napi]. For example usage, see the `asyncresource.cpp` example in the `test/cpp` directory.
+
+<a name="api_nan_make_callback"></a>
+### Nan::MakeCallback()
+
+Deprecated wrappers around the legacy `node::MakeCallback()` APIs. Node.js 10+
+has deprecated these legacy APIs as they do not provide a mechanism to preserve
+async context.
+
+We recommend that you use the `AsyncResource` class and `AsyncResource::runInAsyncScope` instead of using `Nan::MakeCallback` or
+`v8::Function#Call()` directly. `AsyncResource` properly takes care of running the callback in the correct async execution
+context – something that is essential for functionality like domains, async_hooks and async debugging.

+## Object Wrappers

+   *

+   */
+  virtual void Unref();
+
+  int refs_;  // ro
+};
+```
+
+See the Node documentation on [Wrapping C++ Objects](https://nodejs.org/api/addons.html#addons_wrapping_c_objects) for more details.
+
+### This vs. Holder
+
+When calling `Unwrap`, it is important that the argument is indeed some JavaScript object which got wrapped by a `Wrap` call for this class or any derived class.
+The `Signature` installed by [`Nan::SetPrototypeMethod()`](methods.md#api_nan_set_prototype_method) does ensure that `info.Holder()` is just such an instance.
+In Node 0.12 and later, `info.This()` will also be of such a type, since otherwise the invocation will get rejected.
+However, in Node 0.10 and before it was possible to invoke a method on a JavaScript object which just had the extension type in its prototype chain.
+In such a situation, calling `Unwrap` on `info.This()` will likely lead to a failed assertion causing a crash, but could lead to even more serious corruption.
+
+On the other hand, calling `Unwrap` in an [accessor](methods.md#api_nan_set_accessor) should not use `Holder()` if the accessor is defined on the prototype.
+So either define your accessors on the instance template,
+or use `This()` after verifying that it is indeed a valid object.
+
+### Examples
+
+#### Basic
+
+```c++
+class MyObject : public Nan::ObjectWrap {
+ public:
+  static NAN_MODULE_INIT(Init) {
+    v8::Local<v8::FunctionTemplate> tpl = Nan::New<v8::FunctionTemplate>(New);
+    tpl->SetClassName(Nan::New("MyObject").ToLocalChecked());
+    tpl->InstanceTemplate()->SetInternalFieldCount(1);
+
+    Nan::SetPrototypeMethod(tpl, "getHandle", GetHandle);
+    Nan::SetPrototypeMethod(tpl, "getValue", GetValue);
+
+    constructor().Reset(Nan::GetFunction(tpl).ToLocalChecked());
+    Nan::Set(target, Nan::New("MyObject").ToLocalChecked(),
+      Nan::GetFunction(tpl).ToLocalChecked());
+  }
+
+ private:
+  explicit MyObject(double value = 0) : value_(value) {}
+  ~MyObject() {}
+
+  static NAN_METHOD(New) {
+    if (info.IsConstructCall()) {
+      double value = info[0]->IsUndefined() ? 0 : Nan::To<double>(info[0]).FromJust();
+      MyObject *obj = new MyObject(value);
+      obj->Wrap(info.This());
+      info.GetReturnValue().Set(info.This());
+    } else {
+      const int argc = 1;
+      v8::Local<v8::Value> argv[argc] = {info[0]};
+      v8::Local<v8::Function> cons = Nan::New(constructor());
+      info.GetReturnValue().Set(cons->NewInstance(argc, argv));
+    }
+  }
+
+  static NAN_METHOD(GetHandle) {
+    MyObject* obj = Nan::ObjectWrap::Unwrap<MyObject>(info.Holder());
+    info.GetReturnValue().Set(obj->handle());
+  }
+
+  static NAN_METHOD(GetValue) {
+    MyObject* obj = Nan::ObjectWrap::Unwrap<MyObject>(info.Holder());
+    info.GetReturnValue().Set(obj->value_);
+  }
+
+  static inline Nan::Persistent<v8::Function> & constructor() {
+    static Nan::Persistent<v8::Function> my_constructor;
+    return my_constructor;
+  }
+
+  double value_;
+};
+
+NODE_MODULE(objectwrapper, MyObject::Init)
+```
+
+To use in Javascript:
+
+```Javascript
+var objectwrapper = require('bindings')('objectwrapper');
+
+var obj = new objectwrapper.MyObject(5);
+console.log('Should be 5: ' + obj.getValue());
+```
+
+#### Factory of wrapped objects
+
+```c++
+class MyFactoryObject : public Nan::ObjectWrap {
+ public:
+  static NAN_MODULE_INIT(Init) {
+    v8::Local<v8::FunctionTemplate> tpl = Nan::New<v8::FunctionTemplate>(New);
+    tpl->InstanceTemplate()->SetInternalFieldCount(1);
+
+    Nan::SetPrototypeMethod(tpl, "getValue", GetValue);
+
+    constructor().Reset(Nan::GetFunction(tpl).ToLocalChecked());
+  }
+
+  static NAN_METHOD(NewInstance) {
+    v8::Local<v8::Function> cons = Nan::New(constructor());

+    info.GetReturnValue().Set(Nan::NewInstance(cons, argc, argv).ToLocalChecked());
+  }
+
+  // Needed for the next example:
+  inline double value() const {
+    return value_;
+  }
+
+ private:

+      info.GetReturnValue().Set(Nan::NewInstance(cons, argc, argv).ToLocalChecked());
+    }
+  }
+

+      Nan::New<v8::FunctionTemplate>(MyFactoryObject::NewInstance)).ToLocalChecked()
+  );
+}
+
+NODE_MODULE(wrappedobjectfactory, Init)

+
+var obj = wrappedobjectfactory.newFactoryObjectInstance(10);
+console.log('Should be 10: ' + obj.getValue());
+```
+
+#### Passing wrapped objects around
+
+Use the `MyFactoryObject` class above along with the following:
+
+```c++
+static NAN_METHOD(Sum) {
+  Nan::MaybeLocal<v8::Object> maybe1 = Nan::To<v8::Object>(info[0]);
+  Nan::MaybeLocal<v8::Object> maybe2 = Nan::To<v8::Object>(info[1]);
+
+  // Quick check:

+    // return value is undefined by default
+    return;
+  }
+
+  MyFactoryObject* obj1 =
+    Nan::ObjectWrap::Unwrap<MyFactoryObject>(maybe1.ToLocalChecked());
+  MyFactoryObject* obj2 =
+    Nan::ObjectWrap::Unwrap<MyFactoryObject>(maybe2.ToLocalChecked());
+
+  info.GetReturnValue().Set(Nan::New<v8::Number>(obj1->value() + obj2->value()));
+}
+
+NAN_MODULE_INIT(Init) {
+  MyFactoryObject::Init(target);
+  Nan::Set(target,
+    Nan::New<v8::String>("newFactoryObjectInstance").ToLocalChecked(),
+    Nan::GetFunction(
+      Nan::New<v8::FunctionTemplate>(MyFactoryObject::NewInstance)).ToLocalChecked()
+  );
+  Nan::Set(target,
+    Nan::New<v8::String>("sum").ToLocalChecked(),
+    Nan::GetFunction(Nan::New<v8::FunctionTemplate>(Sum)).ToLocalChecked()
+  );
+}
+
+NODE_MODULE(myaddon, Init)
+```
+
+To use in Javascript:
+
+```Javascript
+var myaddon = require('bindings')('myaddon');
+
+var obj1 = myaddon.newFactoryObjectInstance(5);
+var obj2 = myaddon.newFactoryObjectInstance(10);
+console.log('sum of object values: ' + myaddon.sum(obj1, obj2));

+## Persistent references
+
+An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
+
+Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

+### Nan::PersistentBase & v8::PersistentBase
+
+A persistent handle contains a reference to a storage cell in V8 which holds an object value and which is updated by the garbage collector whenever the object is moved. A new storage cell can be created using the constructor or `Nan::PersistentBase::Reset()`. Existing handles can be disposed using an argument-less `Nan::PersistentBase::Reset()`.
+
+Definition:
+
+_(note: this is implemented as `Nan::PersistentBase` for older versions of V8 and the native `v8::PersistentBase` is used for newer versions of V8)_

+<a name="api_nan_weak_callback_info"></a>
+### Nan::WeakCallbackInfo
+
+`Nan::WeakCallbackInfo` is used as an argument when setting a persistent reference as weak. You may need to free any external resources attached to the object. It is a mirror of `v8:WeakCallbackInfo` as found in newer versions of V8.
+
+Definition:
+
+```c++
+template<typename T> class WeakCallbackInfo {
+ public:
+  typedef void (*Callback)(const WeakCallbackInfo<T>& data);
+
+  v8::Isolate *GetIsolate() const;
+
+  /**
+   * Get the parameter that was associated with the weak handle.
+   */
+  T *GetParameter() const;
+
+  /**
+   * Get pointer from internal field, index can be 0 or 1.
+   */
+  void *GetInternalField(int index) const;
+};
+```
+
+Example usage:
+
+```c++
+void weakCallback(const WeakCallbackInfo<int> &data) {
+  int *parameter = data.GetParameter();
+  delete parameter;
+}
+
+Persistent<v8::Object> obj;
+int *data = new int(0);
+obj.SetWeak(data, callback, WeakCallbackType::kParameter);
+```
+
+See the V8 documentation for [`WeakCallbackInfo`](https://v8docs.nodesource.com/io.js-3.3/d8/d06/classv8_1_1_weak_callback_info.html) for further information.
+
+<a name="api_nan_weak_callback_type"></a>
+### Nan::WeakCallbackType
+
+Represents the type of a weak callback.
+A weak callback of type `kParameter` makes the supplied parameter to `Nan::PersistentBase::SetWeak` available through `WeakCallbackInfo::GetParameter`.
+A weak callback of type `kInternalFields` uses up to two internal fields at indices 0 and 1 on the `Nan::PersistentBase<v8::Object>` being made weak.
+Note that only `v8::Object`s and derivatives can have internal fields.
+
+Definition:
+
+```c++
+enum class WeakCallbackType { kParameter, kInternalFields };
+```

+## Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection).
+
+<a name="api_nan_handle_scope"></a>
+### Nan::HandleScope
+
+A simple wrapper around [`v8::HandleScope`](https://v8docs.nodesource.com/io.js-3.3/d3/d95/classv8_1_1_handle_scope.html).
+
+Definition:
+
+```c++
+class Nan::HandleScope {
+ public:
+  Nan::HandleScope();
+  static int NumberOfHandles();
+};
+```
+
+Allocate a new `Nan::HandleScope` whenever you are creating new V8 JavaScript objects. Note that an implicit `HandleScope` is created for you on JavaScript-accessible methods so you do not need to insert one yourself.
+
+Example:
+
+```c++
+// new object is created, it needs a new scope:
+void Pointless() {
+  Nan::HandleScope scope;
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+
+// JavaScript-accessible method already has a HandleScope
+NAN_METHOD(Pointless2) {
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+```
+
+<a name="api_nan_escapable_handle_scope"></a>
+### Nan::EscapableHandleScope
+
+Similar to [`Nan::HandleScope`](#api_nan_handle_scope) but should be used in cases where a function needs to return a V8 JavaScript type that has been created within it.
+
+Definition:
+
+```c++
+class Nan::EscapableHandleScope {
+ public:
+  Nan::EscapableHandleScope();
+  static int NumberOfHandles();
+  template<typename T> v8::Local<T> Escape(v8::Local<T> value);
+}
+```
+
+Use `Escape(value)` to return the object.
+
+Example:
+
+```c++
+v8::Local<v8::Object> EmptyObj() {
+  Nan::EscapableHandleScope scope;
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+  return scope.Escape(obj);
+}
+```

+### Nan::Utf8String
+
+Converts an object to a UTF-8-encoded character array. If conversion to a string fails (e.g. due to an exception in the toString() method of the object) then the length() method returns 0 and the * operator returns NULL. The underlying memory used for this object is managed by the object.
+
+An implementation of [`v8::String::Utf8Value`](https://v8docs.nodesource.com/io.js-3.3/d4/d1b/classv8_1_1_string_1_1_utf8_value.html) that is consistent across all supported versions of V8.
+
+Definition:
+
+```c++
+class Nan::Utf8String {
+ public:
+  Nan::Utf8String(v8::Local<v8::Value> from);
+
+  int length() const;
+
+  char* operator*();
+  const char* operator*() const;
+};
+```
+
+<a name="api_nan_get_current_context"></a>

+
+Signature:
+
+```c++
+v8::Local<v8::Context> Nan::GetCurrentContext()
+```
+
+<a name="api_nan_set_isolate_data"></a>
+### Nan::SetIsolateData()
+
+A helper to provide a consistent API to [`v8::Isolate#SetData()`](https://v8docs.nodesource.com/io.js-3.3/d5/dda/classv8_1_1_isolate.html#a7acadfe7965997e9c386a05f098fbe36).

+
+```c++
+void Nan::SetIsolateData(v8::Isolate *isolate, T *data)
+```
+
+
+<a name="api_nan_get_isolate_data"></a>
+### Nan::GetIsolateData()
+
+A helper to provide a consistent API to [`v8::Isolate#GetData()`](https://v8docs.nodesource.com/io.js-3.3/d5/dda/classv8_1_1_isolate.html#aabd223436bc1100a787dadaa024c6257).
+
+Signature:

+```c++
+T *Nan::GetIsolateData(v8::Isolate *isolate)
+```
+
+<a name="api_nan_typedarray_contents"></a>
+### Nan::TypedArrayContents<T>
+
+A helper class for accessing the contents of an ArrayBufferView (aka a typedarray) from C++.  If the input array is not a valid typedarray, then the data pointer of TypedArrayContents will default to `NULL` and the length will be 0.  If the data pointer is not compatible with the alignment requirements of type, an assertion error will fail.
+
+Note that you must store a reference to the `array` object while you are accessing its contents.
+
+Definition:
+
+```c++
+template<typename T>
+class Nan::TypedArrayContents {
+ public:
+  TypedArrayContents(v8::Local<Value> array);
+
+  size_t length() const;
+
+  T* const operator*();
+  const T* const operator*() const;
+};

+# ncp - Asynchronous recursive file & directory copying
+
+[![Build Status](https://secure.travis-ci.org/AvianFlu/ncp.png)](http://travis-ci.org/AvianFlu/ncp)
+
+Think `cp -r`, but pure node, and asynchronous.  `ncp` can be used both as a CLI tool and programmatically.
+
+## Command Line usage
+
+Usage is simple: `ncp [source] [dest] [--limit=concurrency limit]
+[--filter=filter] --stopOnErr`
+
+The 'filter' is a Regular Expression - matched files will be copied.
+
+The 'concurrency limit' is an integer that represents how many pending file system requests `ncp` has at a time.
+
+'stoponerr' is a boolean flag that will tell `ncp` to stop immediately if any
+errors arise, rather than attempting to continue while logging errors. The default behavior is to complete as many copies as possible, logging errors along the way.
+
+If there are no errors, `ncp` will output `done.` when complete.  If there are errors, the error messages will be logged to `stdout` and to `./ncp-debug.log`, and the copy operation will attempt to continue.
+
+## Programmatic usage
+
+Programmatic usage of `ncp` is just as simple.  The only argument to the completion callback is a possible error.  
+
+```javascript
+var ncp = require('ncp').ncp;
+
+ncp.limit = 16;
+
+ncp(source, destination, function (err) {
+ if (err) {
+   return console.error(err);
+ }
+ console.log('done!');
+});
+```
+
+You can also call ncp like `ncp(source, destination, options, callback)`. 
+`options` should be a dictionary. Currently, such options are available:
+
+  * `options.filter` - a `RegExp` instance, against which each file name is
+  tested to determine whether to copy it or not, or a function taking single
+  parameter: copied file name, returning `true` or `false`, determining
+  whether to copy file or not.
+
+  * `options.transform` - a function: `function (read, write) { read.pipe(write) }`
+  used to apply streaming transforms while copying.
+
+  * `options.clobber` - boolean=true. if set to false, `ncp` will not overwrite 
+  destination files that already exist.
+
+  * `options.dereference` - boolean=false. If set to true, `ncp` will follow symbolic
+  links. For example, a symlink in the source tree pointing to a regular file
+  will become a regular file in the destination tree. Broken symlinks will result in
+  errors.
+
+  * `options.stopOnErr` - boolean=false.  If set to true, `ncp` will behave like `cp -r`,
+  and stop on the first error it encounters. By default, `ncp` continues copying, logging all
+  errors and returning an array.
+
+  * `options.errs` - stream. If `options.stopOnErr` is `false`, a stream can be provided, and errors will be written to this stream.
+
+Please open an issue if any bugs arise.  As always, I accept (working) pull requests, and refunds are available at `/dev/null`.

+$ npm install negotiator
+```
+
+## API
+
+```js
+var Negotiator = require('negotiator')
+```
+
+### Accept Negotiation
+
+```js
+availableMediaTypes = ['text/html', 'text/plain', 'application/json']
+
+// The negotiator constructor receives a request object
+negotiator = new Negotiator(request)
+
+// Let's say Accept header is 'text/html, application/*;q=0.2, image/jpeg;q=0.8'
+
+negotiator.mediaTypes()
+// -> ['text/html', 'image/jpeg', 'application/*']
+
+negotiator.mediaTypes(availableMediaTypes)
+// -> ['text/html', 'application/json']
+
+negotiator.mediaType(availableMediaTypes)
+// -> 'text/html'
+```
+
+You can check a working example at `examples/accept.js`.
+
+#### Methods
+
+##### mediaType()
+
+Returns the most preferred media type from the client.
+
+##### mediaType(availableMediaType)
+
+Returns the most preferred media type from a list of available media types.
+
+##### mediaTypes()
+
+Returns an array of preferred media types ordered by the client preference.
+
+##### mediaTypes(availableMediaTypes)
+
+Returns an array of preferred media types ordered by priority from a list of
+available media types.
+
+### Accept-Language Negotiation
+
+```js
+negotiator = new Negotiator(request)
+
+availableLanguages = ['en', 'es', 'fr']
+
+// Let's say Accept-Language header is 'en;q=0.8, es, pt'
+
+negotiator.languages()
+// -> ['es', 'pt', 'en']
+
+negotiator.languages(availableLanguages)
+// -> ['es', 'en']
+
+language = negotiator.language(availableLanguages)
+// -> 'es'
+```
+
+You can check a working example at `examples/language.js`.
+
+#### Methods
+
+##### language()
+
+Returns the most preferred language from the client.
+
+##### language(availableLanguages)
+
+Returns the most preferred language from a list of available languages.
+
+##### languages()
+
+Returns an array of preferred languages ordered by the client preference.
+
+##### languages(availableLanguages)
+
+Returns an array of preferred languages ordered by priority from a list of
+available languages.
+
+### Accept-Charset Negotiation
+
+```js
+availableCharsets = ['utf-8', 'iso-8859-1', 'iso-8859-5']
+
+negotiator = new Negotiator(request)
+
+// Let's say Accept-Charset header is 'utf-8, iso-8859-1;q=0.8, utf-7;q=0.2'
+
+negotiator.charsets()
+// -> ['utf-8', 'iso-8859-1', 'utf-7']
+
+negotiator.charsets(availableCharsets)
+// -> ['utf-8', 'iso-8859-1']
+
+negotiator.charset(availableCharsets)
+// -> 'utf-8'
+```
+
+You can check a working example at `examples/charset.js`.
+
+#### Methods
+
+##### charset()
+
+Returns the most preferred charset from the client.
+
+##### charset(availableCharsets)
+
+Returns the most preferred charset from a list of available charsets.
+
+##### charsets()
+
+Returns an array of preferred charsets ordered by the client preference.
+
+##### charsets(availableCharsets)
+
+Returns an array of preferred charsets ordered by priority from a list of
+available charsets.
+
+### Accept-Encoding Negotiation
+
+```js
+availableEncodings = ['identity', 'gzip']
+
+negotiator = new Negotiator(request)
+
+// Let's say Accept-Encoding header is 'gzip, compress;q=0.2, identity;q=0.5'
+
+negotiator.encodings()
+// -> ['gzip', 'identity', 'compress']
+
+negotiator.encodings(availableEncodings)
+// -> ['gzip', 'identity']
+
+negotiator.encoding(availableEncodings)
+// -> 'gzip'
+```
+
+You can check a working example at `examples/encoding.js`.
+
+#### Methods
+
+##### encoding()
+
+Returns the most preferred encoding from the client.
+
+##### encoding(availableEncodings)
+
+Returns the most preferred encoding from a list of available encodings.
+
+##### encodings()
+
+Returns an array of preferred encodings ordered by the client preference.
+
+##### encodings(availableEncodings)
+
+Returns an array of preferred encodings ordered by priority from a list of
+available encodings.

+# node-pty
+
+[![Build Status](https://dev.azure.com/vscode/node-pty/_apis/build/status/Microsoft.node-pty)](https://dev.azure.com/vscode/node-pty/_build/latest?definitionId=11)
+
+`forkpty(3)` bindings for node.js. This allows you to fork processes with pseudoterminal file descriptors. It returns a terminal object which allows reads and writes.
+
+This is useful for:
+
+- Writing a terminal emulator (eg. via [xterm.js](https://github.com/sourcelair/xterm.js)).
+- Getting certain programs to *think* you're a terminal, such as when you need a program to send you control sequences.
+
+`node-pty` supports Linux, macOS and Windows. Windows support is possible by utilizing the [Windows conpty API](https://blogs.msdn.microsoft.com/commandline/2018/08/02/windows-command-line-introducing-the-windows-pseudo-console-conpty/) on Windows 1809+ and the [winpty](https://github.com/rprichard/winpty) library in older version.
+
+## Real-world Uses
+
+`node-pty` powers many different terminal emulators, including:
+
+- [Microsoft Visual Studio Code](https://code.visualstudio.com)
+- [Hyper](https://hyper.is/)
+- [Upterm](https://github.com/railsware/upterm)
+- [Script Runner](https://github.com/ioquatix/script-runner) for Atom.
+- [Theia](https://github.com/theia-ide/theia)
+- [FreeMAN](https://github.com/matthew-matvei/freeman) file manager
+- [atom-xterm](https://atom.io/packages/atom-xterm) - Atom plugin for providing terminals inside your Atom workspace.
+- [Termination](https://atom.io/packages/termination) - Another Atom plugin that provides terminals inside your Atom workspace.
+- [electerm](https://github.com/electerm/electerm) Terminal/ssh/sftp client(linux, mac, win).
+- [Extraterm](http://extraterm.org/)
+- [Wetty](https://github.com/krishnasrinivas/wetty) Browser based Terminal over HTTP and HTTPS
+
+Do you use node-pty in your application as well? Please open a [Pull Request](https://github.com/Tyriar/node-pty/pulls) to include it here. We would love to have it in our list.
+
+## Example Usage
+
+```js
+var os = require('os');
+var pty = require('node-pty');
+
+var shell = os.platform() === 'win32' ? 'powershell.exe' : 'bash';
+
+var ptyProcess = pty.spawn(shell, [], {
+  name: 'xterm-color',
+  cols: 80,
+  rows: 30,
+  cwd: process.env.HOME,
+  env: process.env
+});
+
+ptyProcess.on('data', function(data) {
+  process.stdout.write(data);
+});
+
+ptyProcess.write('ls\r');
+ptyProcess.resize(100, 40);
+ptyProcess.write('ls\r');
+```
+
+## Building
+
+```bash
+# Install dependencies and build C++
+npm install
+# Compile TypeScript -> JavaScript
+npm run tsc
+```
+
+## Dependencies
+
+### Linux/Ubuntu
+
+```
+sudo apt install -y make python build-essential
+```
+
+The following are also needed:
+
+- Node.JS 10+
+
+### Windows
+
+`npm install` requires some tools to be present in the system like Python and C++ compiler. Windows users can easily install them by running the following command in PowerShell as administrator. For more information see https://github.com/felixrieseberg/windows-build-tools:
+
+```sh
+npm install --global --production windows-build-tools
+```
+
+The following are also needed:
+
+- [Windows SDK](https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk) - only the "Desktop C++ Apps" components are needed to be installed
+- Node.JS 10+
+
+## Debugging
+
+[The wiki](https://github.com/Microsoft/node-pty/wiki/Debugging) contains instructions for debugging node-pty.
+
+## Security
+
+All processes launched from node-pty will launch at the same permission level of the parent process. Take care particularly when using node-pty inside a server that's accessible on the internet. We recommend launching the pty inside a container to protect your host machine.
+
+## Thread Safety
+
+Note that node-pty is not thread safe so running it across multiple worker threads in node.js could cause issues.
+
+## Flow Control
+
+Automatic flow control can be enabled by either providing `handleFlowControl = true` in the constructor options or setting it later on:
+
+```js
+const PAUSE = '\x13';   // XOFF
+const RESUME = '\x11';  // XON
+
+const ptyProcess = pty.spawn(shell, [], {handleFlowControl: true});
+
+// flow control in action
+ptyProcess.write(PAUSE);  // pty will block and pause the slave program
+...
+ptyProcess.write(RESUME); // pty will enter flow mode and resume the slave program
+
+// temporarily disable/re-enable flow control
+ptyProcess.handleFlowControl = false;
+...
+ptyProcess.handleFlowControl = true;
+```
+
+By default `PAUSE` and `RESUME` are XON/XOFF control codes (as shown above). To avoid conflicts in environments that use these control codes for different purposes the messages can be customized as `flowControlPause: string` and `flowControlResume: string` in the constructor options. `PAUSE` and `RESUME` are not passed to the underlying pseudoterminal if flow control is enabled.
+
+## Troubleshooting
+
+### Powershell gives error 8009001d
+
+> Internal Windows PowerShell error.  Loading managed Windows PowerShell failed with error 8009001d.
+
+This happens when PowerShell is launched with no `SystemRoot` environment variable present.
+
+### ConnectNamedPipe failed: Windows error 232
+
+This error can occur due to anti-virus software intercepting winpty from creating a pty. To workaround this you can exclude this file from your anti-virus scanning `node-pty\build\Release\winpty-agent.exe`
+
+## pty.js
+
+This project is forked from [chjj/pty.js](https://github.com/chjj/pty.js) with the primary goals being to provide better support for later Node.JS versions and Windows.

+# winpty
+
+[![Build Status](https://tea-ci.org/api/badges/rprichard/winpty/status.svg)](https://tea-ci.org/rprichard/winpty)
+
+winpty is a Windows software package providing an interface similar to a Unix
+pty-master for communicating with Windows console programs.  The package
+consists of a library (libwinpty) and a tool for Cygwin and MSYS for running
+Windows console programs in a Cygwin/MSYS pty.
+
+The software works by starting the `winpty-agent.exe` process with a new,
+hidden console window, which bridges between the console API and terminal
+input/output escape codes.  It polls the hidden console's screen buffer for
+changes and generates a corresponding stream of output.
+
+The Unix adapter allows running Windows console programs (e.g. CMD, PowerShell,
+IronPython, etc.) under `mintty` or Cygwin's `sshd` with
+properly-functioning input (e.g. arrow and function keys) and output (e.g. line
+buffering).  The library could be also useful for writing a non-Cygwin SSH
+server.
+
+## Supported Windows versions
+
+winpty runs on Windows XP through Windows 10, including server versions.  It
+can be compiled into either 32-bit or 64-bit binaries.
+
+## Cygwin/MSYS adapter (`winpty.exe`)
+
+### Prerequisites
+
+You need the following to build winpty:
+
+* A Cygwin or MSYS installation
+* GNU make
+* A MinGW g++ toolchain capable of compiling C++11 code to build `winpty.dll`
+  and `winpty-agent.exe`
+* A g++ toolchain targeting Cygwin or MSYS to build `winpty.exe`
+
+Winpty requires two g++ toolchains as it is split into two parts. The
+`winpty.dll` and `winpty-agent.exe` binaries interface with the native
+Windows command prompt window so they are compiled with the native MinGW
+toolchain.  The `winpty.exe` binary interfaces with the MSYS/Cygwin terminal so
+it is compiled with the MSYS/Cygwin toolchain.
+
+MinGW appears to be split into two distributions -- MinGW (creates 32-bit
+binaries) and MinGW-w64 (creates both 32-bit and 64-bit binaries).  Either
+one is generally acceptable.
+
+#### Cygwin packages
+
+The default g++ compiler for Cygwin targets Cygwin itself, but Cygwin also
+packages MinGW-w64 compilers.  As of this writing, the necessary packages are:
+
+* Either `mingw64-i686-gcc-g++` or `mingw64-x86_64-gcc-g++`.  Select the
+  appropriate compiler for your CPU architecture.
+* `gcc-g++`
+* `make`
+
+As of this writing (2016-01-23), only the MinGW-w64 compiler is acceptable.
+The MinGW compiler (e.g. from the `mingw-gcc-g++` package) is no longer
+maintained and is too buggy.
+
+#### MSYS packages
+
+For the original MSYS, use the `mingw-get` tool (MinGW Installation Manager),
+and select at least these components:
+
+* `mingw-developer-toolkit`
+* `mingw32-base`
+* `mingw32-gcc-g++`
+* `msys-base`
+* `msys-system-builder`
+
+When running `./configure`, make sure that `mingw32-g++` is in your
+`PATH`.  It will be in the `C:\MinGW\bin` directory.
+
+#### MSYS2 packages
+
+For MSYS2, use `pacman` and install at least these packages:
+
+* `msys/gcc`
+* `mingw32/mingw-w64-i686-gcc` or `mingw64/mingw-w64-x86_64-gcc`.  Select
+  the appropriate compiler for your CPU architecture.
+* `make`
+
+MSYS2 provides three start menu shortcuts for starting MSYS2:
+
+* MinGW-w64 Win32 Shell
+* MinGW-w64 Win64 Shell
+* MSYS2 Shell
+
+To build winpty, use the MinGW-w64 {Win32,Win64} shortcut of the architecture
+matching MSYS2.  These shortcuts will put the g++ compiler from the
+`{mingw32,mingw64}/mingw-w64-{i686,x86_64}-gcc` packages into the `PATH`.
+
+Alternatively, instead of installing `mingw32/mingw-w64-i686-gcc` or
+`mingw64/mingw-w64-x86_64-gcc`, install the `mingw-w64-cross-gcc` and
+`mingw-w64-cross-crt-git` packages.  These packages install cross-compilers
+into `/opt/bin`, and then any of the three shortcuts will work.
+
+### Building the Unix adapter
+
+In the project directory, run `./configure`, then `make`, then `make install`.
+By default, winpty is installed into `/usr/local`.  Pass `PREFIX=<path>` to
+`make install` to override this default.
+
+### Using the Unix adapter
+
+To run a Windows console program in `mintty` or Cygwin `sshd`, prepend
+`winpty` to the command-line:
+
+    $ winpty powershell
+    Windows PowerShell
+    Copyright (C) 2009 Microsoft Corporation. All rights reserved.
+
+    PS C:\rprichard\proj\winpty> 10 + 20
+    30
+    PS C:\rprichard\proj\winpty> exit
+
+## Embedding winpty / MSVC compilation
+
+See `src/include/winpty.h` for the prototypes of functions exported by
+`winpty.dll`.
+
+Only the `winpty.exe` binary uses Cygwin; all the other binaries work without
+it and can be compiled with either MinGW or MSVC.  To compile using MSVC,
+download gyp and run `gyp -I configurations.gypi` in the `src` subdirectory.
+This will generate a `winpty.sln` and associated project files.  See the
+`src/winpty.gyp` and `src/configurations.gypi` files for notes on dealing with
+MSVC versions and different architectures.
+
+Compiling winpty with MSVC currently requires MSVC 2013 or newer.
+
+## Debugging winpty
+
+winpty comes with a tool for collecting timestamped debugging output.  To use
+it:
+
+1. Run `winpty-debugserver.exe` on the same computer as winpty.
+2. Set the `WINPTY_DEBUG` environment variable to `trace` for the
+   `winpty.exe` process and/or the process using `libwinpty.dll`.
+
+winpty also recognizes a `WINPTY_SHOW_CONSOLE` environment variable.  Set it
+to 1 to prevent winpty from hiding the console window.

+# Next Version
+
+Input handling changes:
+
+ * Improve Ctrl-C handling with programs that use unprocessed input. (e.g.
+   Ctrl-C now cancels input with PowerShell on Windows 10.)
+   [#116](https://github.com/rprichard/winpty/issues/116)
+ * Fix a theoretical issue with input event ordering.
+   [#117](https://github.com/rprichard/winpty/issues/117)
+ * Ctrl/Shift+{Arrow,Home,End} keys now work with IntelliJ.
+   [#118](https://github.com/rprichard/winpty/issues/118)
+
+# Version 0.4.3 (2017-05-17)
+
+Input handling changes:
+
+ * winpty sets `ENHANCED_KEY` for arrow and navigation keys.  This fixes an
+   issue with the Ruby REPL.
+   [#99](https://github.com/rprichard/winpty/issues/99)
+ * AltGr keys are handled better now.
+   [#109](https://github.com/rprichard/winpty/issues/109)
+ * In `ENABLE_VIRTUAL_TERMINAL_INPUT` mode, when typing Home/End with a
+   modifier (e.g. Ctrl), winpty now generates an H/F escape sequence like
+   `^[[1;5F` rather than a 1/4 escape like `^[[4;5~`.
+   [#114](https://github.com/rprichard/winpty/issues/114)
+
+Resizing and scraping fixes:
+
+ * winpty now synthesizes a `WINDOW_BUFFER_SIZE_EVENT` event after resizing
+   the console to better propagate window size changes to console programs.
+   In particular, this affects WSL and Cygwin.
+   [#110](https://github.com/rprichard/winpty/issues/110)
+ * Better handling of resizing for certain full-screen programs, like
+   WSL less.
+   [#112](https://github.com/rprichard/winpty/issues/112)
+ * Hide the cursor if it's currently outside the console window.  This change
+   fixes an issue with Far Manager.
+   [#113](https://github.com/rprichard/winpty/issues/113)
+ * winpty now avoids using console fonts smaller than 5px high to improve
+   half-vs-full-width character handling.  See
+   https://github.com/Microsoft/vscode/issues/19665.
+   [b4db322010](https://github.com/rprichard/winpty/commit/b4db322010d2d897e6c496fefc4f0ecc9b84c2f3)
+
+Cygwin/MSYS adapter fix:
+
+ * The way the `winpty` Cygwin/MSYS2 adapter searches for the program to
+   launch changed.  It now resolves symlinks and searches the PATH explicitly.
+   [#81](https://github.com/rprichard/winpty/issues/81)
+   [#98](https://github.com/rprichard/winpty/issues/98)
+
+This release does not include binaries for the old MSYS1 project anymore.
+MSYS2 will continue to be supported.  See
+https://github.com/rprichard/winpty/issues/97.
+
+# Version 0.4.2 (2017-01-18)
+
+This release improves WSL support (i.e. Bash-on-Windows):
+
+ * winpty generates more correct input escape sequences for WSL programs that
+   enable an alternate input mode using DECCKM.  This bug affected arrow keys
+   and Home/End in WSL programs such as `vim`, `mc`, and `less`.
+   [#90](https://github.com/rprichard/winpty/issues/90)
+ * winpty now recognizes the `COMMON_LVB_REVERSE_VIDEO` and
+   `COMMON_LVB_UNDERSCORE` text attributes.  The Windows console uses these
+   attributes to implement the SGR.4(Underline) and SGR.7(Negative) modes in
+   its VT handling.  This change affects WSL pager status bars, man pages, etc.
+
+The build system no longer has a "version suffix" mechanism, so passing
+`VERSION_SUFFIX=<suffix>` to make or `-D VERSION_SUFFIX=<suffix>` to gyp now
+has no effect.  AFAIK, the mechanism was never used publicly.
+[67a34b6c03](https://github.com/rprichard/winpty/commit/67a34b6c03557a5c2e0a2bdd502c2210921d8f3e)
+
+# Version 0.4.1 (2017-01-03)
+
+Bug fixes:
+
+ * This version fixes a bug where the `winpty-agent.exe` process could read
+   past the end of a buffer.
+   [#94](https://github.com/rprichard/winpty/issues/94)
+
+# Version 0.4.0 (2016-06-28)
+
+The winpty library has a new API that should be easier for embedding.
+[880c00c69e](https://github.com/rprichard/winpty/commit/880c00c69eeca73643ddb576f02c5badbec81f56)
+
+User-visible changes:
+
+ * winpty now automatically puts the terminal into mouse mode when it detects
+   that the console has left QuickEdit mode.  The `--mouse` option still forces
+   the terminal into mouse mode.  In principle, an option could be added to
+   suppress terminal mode, but hopefully it won't be necessary.  There is a
+   script in the `misc` subdirectory, `misc/ConinMode.ps1`, that can change
+   the QuickEdit mode from the command-line.
+ * winpty now passes keyboard escapes to `bash.exe` in the Windows Subsystem
+   for Linux.
+   [#82](https://github.com/rprichard/winpty/issues/82)
+
+Bug fixes:
+
+ * By default, `winpty.dll` avoids calling `SetProcessWindowStation` within
+   the calling process.
+   [#58](https://github.com/rprichard/winpty/issues/58)
+ * Fixed an uninitialized memory bug that could have crashed winpty.
+   [#80](https://github.com/rprichard/winpty/issues/80)
+ * winpty now works better with very large and very small terminal windows.
+   It resizes the console font according to the number of columns.
+   [#61](https://github.com/rprichard/winpty/issues/61)
+ * winpty no longer uses Mark to freeze the console on Windows 10.  The Mark
+   command could interfere with the cursor position, corrupting the data in
+   the screen buffer.
+   [#79](https://github.com/rprichard/winpty/issues/79)
+
+# Version 0.3.0 (2016-05-20)
+
+User-visible changes:
+
+ * The UNIX adapter is renamed from `console.exe` to `winpty.exe` to be
+   consistent with MSYS2.  The name `winpty.exe` is less likely to conflict
+   with another program and is easier to search for online (e.g. for someone
+   unfamiliar with winpty).
+ * The UNIX adapter now clears the `TERM` variable.
+   [#43](https://github.com/rprichard/winpty/issues/43)
+ * An escape character appearing in a console screen buffer cell is converted
+   to a '?'.
+   [#47](https://github.com/rprichard/winpty/issues/47)
+
+Bug fixes:
+
+ * A major bug affecting XP users was fixed.
+   [#67](https://github.com/rprichard/winpty/issues/67)
+ * Fixed an incompatibility with ConEmu where winpty hung if ConEmu's
+   "Process 'start'" feature was enabled.
+   [#70](https://github.com/rprichard/winpty/issues/70)
+ * Fixed a bug where `cmd.exe` sometimes printed the message,
+   `Not enough storage is available to process this command.`.
+   [#74](https://github.com/rprichard/winpty/issues/74)
+
+Many changes internally:
+
+ * The codebase is switched from C++03 to C++11 and uses exceptions internally.
+   No exceptions are thrown across the C APIs defined in `winpty.h`.
+ * This version drops support for the original MinGW compiler packaged with
+   Cygwin (`i686-pc-mingw32-g++`).  The MinGW-w64 compiler is still supported,
+   as is the MinGW distributed at mingw.org.  Compiling with MSVC now requires
+   MSVC 2013 or newer.  Windows XP is still supported.
+   [ec3eae8df5](https://github.com/rprichard/winpty/commit/ec3eae8df5bbbb36d7628d168b0815638d122f37)
+ * Pipe security is improved.  winpty works harder to produce unique pipe names
+   and includes a random component in the name.  winpty secures pipes with a
+   DACL that prevents arbitrary users from connecting to its pipes.  winpty now
+   passes `PIPE_REJECT_REMOTE_CLIENTS` on Vista and up, and it verifies that
+   the pipe client PID is correct, again on Vista and up.  When connecting to a
+   named pipe, winpty uses the `SECURITY_IDENTIFICATION` flag to restrict
+   impersonation.  Previous versions *should* still be secure.
+ * `winpty-debugserver.exe` now has an `--everyone` flag that allows capturing
+   debug output from other users.
+ * The code now compiles cleanly with MSVC's "Security Development Lifecycle"
+   (`/SDL`) checks enabled.
+
+# Version 0.2.2 (2016-02-25)
+
+Minor bug fixes and enhancements:
+
+ * Fix a bug that generated spurious mouse input records when an incomplete
+   mouse escape sequence was seen.
+ * Fix a buffer overflow bug in `winpty-debugserver.exe` affecting messages of
+   exactly 4096 bytes.
+ * For MSVC builds, add a `src/configurations.gypi` file that can be included
+   on the gyp command-line to enable 32-bit and 64-bit builds.
+ * `winpty-agent --show-input` mode: Flush stdout after each line.
+ * Makefile builds: generate a `build/winpty.lib` import library to accompany
+   `build/winpty.dll`.
+
+# Version 0.2.1 (2015-12-19)
+
+ * The main project source was moved into a `src` directory for better code
+   organization and to fix
+   [#51](https://github.com/rprichard/winpty/issues/51).
+ * winpty recognizes many more escape sequences, including:
+    * putty/rxvt's F1-F4 keys
+      [#40](https://github.com/rprichard/winpty/issues/40)
+    * the Linux virtual console's F1-F5 keys
+    * the "application numpad" keys (e.g. enabled with DECPAM)
+ * Fixed handling of Shift-Alt-O and Alt-[.
+ * Added support for mouse input.  The UNIX adapter has a `--mouse` argument
+   that puts the terminal into mouse mode, but the agent recognizes mouse
+   input even without the argument.  The agent recognizes double-clicks using
+   Windows' double-click interval setting (i.e. GetDoubleClickTime).
+   [#57](https://github.com/rprichard/winpty/issues/57)
+
+Changes to debugging interfaces:
+
+ * The `WINPTY_DEBUG` variable is now a comma-separated list.  The old
+   behavior (i.e. tracing) is enabled with `WINPTY_DEBUG=trace`.
+ * The UNIX adapter program now has a `--showkey` argument that dumps input
+   bytes.
+ * The `winpty-agent.exe` program has a `--show-input` argument that dumps
+   `INPUT_RECORD` records.  (It omits mouse events unless `--with-mouse` is
+   also specified.)  The agent also responds to `WINPTY_DEBUG=trace,input`,
+   which logs input bytes and synthesized console events, and it responds to
+   `WINPTY_DEBUG=trace,dump_input_map`, which dumps the internal table of
+   escape sequences.
+
+# Version 0.2.0 (2015-11-13)
+
+No changes to the API, but many small changes to the implementation.  The big
+changes include:
+
+ * Support for 64-bit Cygwin and MSYS2
+ * Support for Windows 10
+ * Better Unicode support (especially East Asian languages)
+
+Details:
+
+ * The `configure` script recognizes 64-bit Cygwin and MSYS2 environments and
+   selects the appropriate compiler.
+ * winpty works much better with the upgraded console in Windows 10.  The
+   `conhost.exe` hang can still occur, but only with certain programs, and
+   is much less likely to occur.  With the new console, use Mark instead of
+   SelectAll, for better performance.
+   [#31](https://github.com/rprichard/winpty/issues/31)
+   [#30](https://github.com/rprichard/winpty/issues/30)
+   [#53](https://github.com/rprichard/winpty/issues/53)
+ * The UNIX adapter now calls `setlocale(LC_ALL, "")` to set the locale.
+ * Improved Unicode support.  When a console is started with an East Asian code
+   page, winpty now chooses an East Asian font rather than Consolas / Lucida
+   Console.  Selecting the right font helps synchronize character widths
+   between the console and terminal.  (It's not perfect, though.)
+   [#41](https://github.com/rprichard/winpty/issues/41)
+ * winpty now more-or-less works with programs that change the screen buffer
+   or resize the original screen buffer.  If the screen buffer height changes,
+   winpty switches to a "direct mode", where it makes no effort to track
+   scrolling.  In direct mode, it merely syncs snapshots of the console to the
+   terminal.  Caveats:
+    * Changing the screen buffer (i.e. `SetConsoleActiveScreenBuffer`)
+      breaks winpty on Windows 7.  This problem can eventually be mitigated,
+      but never completely fixed, due to Windows 7 bugginess.
+    * Resizing the original screen buffer can hang `conhost.exe` on Windows 10.
+      Enabling the legacy console is a workaround.
+    * If a program changes the screen buffer and then exits, relying on the OS
+      to restore the original screen buffer, that restoration probably will not
+      happen with winpty.  winpty's behavior can probably be improved here.
+ * Improved color handling:
+    * DkGray-on-Black text was previously hiddenly completely.  Now it is
+      output as DkGray, with a fallback to LtGray on terminals that don't
+      recognize the intense colors.
+      [#39](https://github.com/rprichard/winpty/issues/39).
+    * The console is always initialized to LtGray-on-Black, regardless of the
+      user setting, which matches the console color heuristic, which translates
+      LtGray-on-Black to "reset SGR parameters."
+ * Shift-Tab is recognized correctly now.
+   [#19](https://github.com/rprichard/winpty/issues/19)
+ * Add a `--version` argument to `winpty-agent.exe` and the UNIX adapter.  The
+   argument reports the nominal version (i.e. the `VERSION.txt`) file, with a
+   "VERSION_SUFFIX" appended (defaulted to `-dev`), and a git commit hash, if
+   the `git` command successfully reports a hash during the build.  The `git`
+   command is invoked by either `make` or `gyp`.
+ * The agent now combines `ReadConsoleOutputW` calls when it polls the console
+   buffer for changes, which may slightly reduce its CPU overhead.
+   [#44](https://github.com/rprichard/winpty/issues/44).
+ * A `gyp` file is added to help compile with MSVC.
+ * The code can now be compiled as C++11 code, though it isn't by default.
+   [bde8922e08](https://github.com/rprichard/winpty/commit/bde8922e08c3638e01ecc7b581b676c314163e3c)
+ * If winpty can't create a new window station, it charges ahead rather than
+   aborting.  This situation might happen if winpty were started from an SSH
+   session.
+ * Debugging improvements:
+    * `WINPTYDBG` is renamed to `WINPTY_DEBUG`, and a new `WINPTY_SHOW_CONSOLE`
+      variable keeps the underlying console visible.
+    * A `winpty-debugserver.exe` program is built and shipped by default.  It
+      collects the trace output enabled with `WINPTY_DEBUG`.
+ * The `Makefile` build of winpty now compiles `winpty-agent.exe` and
+   `winpty.dll` with -O2.

+Note regarding ENABLE_EXTENDED_FLAGS (2016-05-30)
+
+There is a complicated interaction between the ENABLE_EXTENDED_FLAGS flag
+and the ENABLE_QUICK_EDIT_MODE and ENABLE_INSERT_MODE flags (presumably for
+backwards compatibility?).  I studied the behavior on Windows 7 and Windows
+10, with both the old and new consoles, and I didn't see any differences
+between versions.  Here's what I seemed to observe:
+
+ - The console has three flags internally:
+    - QuickEdit
+    - InsertMode
+    - ExtendedFlags
+
+ - SetConsoleMode psuedocode:
+      void SetConsoleMode(..., DWORD mode) {
+        ExtendedFlags = (mode & (ENABLE_EXTENDED_FLAGS
+                                  | ENABLE_QUICK_EDIT_MODE
+                                  | ENABLE_INSERT_MODE    )) != 0;
+        if (ExtendedFlags) {
+          QuickEdit = (mode & ENABLE_QUICK_EDIT_MODE) != 0;
+          InsertMode = (mode & ENABLE_INSERT_MODE) != 0;
+        }
+      }
+
+ - Setting QuickEdit or InsertMode from the properties dialog GUI does not
+   affect the ExtendedFlags setting -- it simply toggles the one flag.
+
+ - GetConsoleMode psuedocode:
+      GetConsoleMode(..., DWORD *result) {
+        if (ExtendedFlags) {
+          *result |= ENABLE_EXTENDED_FLAGS;
+          if (QuickEdit) { *result |= ENABLE_QUICK_EDIT_MODE; }
+          if (InsertMode) { *result |= ENABLE_INSERT_MODE; }
+        }
+      }
+
+Effectively, the ExtendedFlags flags controls whether the other two flags
+are visible/controlled by the user application.  If they aren't visible,
+though, there is no way for the user application to make them visible,
+except by overwriting their values!  Calling SetConsoleMode with just
+ENABLE_EXTENDED_FLAGS would clear the extended flags we want to read.
+
+Consequently, if a program temporarily alters the QuickEdit flag (e.g. to
+enable mouse input), it cannot restore the original values of the QuickEdit
+and InsertMode flags, UNLESS every other console program cooperates by
+keeping the ExtendedFlags flag set.

+Issues:
+
+ - Starting with the 14342 build, changing the font using
+   SetCurrentConsoleFontEx does not affect the window size.  e.g. The content
+   itself will resize/redraw, but the window neither shrinks nor expands.
+   Presumably this is an oversight?  It's almost a convenience; if a program
+   is going to resize the window anyway, then it's nice that the window size
+   contraints don't get in the way.  Ordinarily, changing the font doesn't just
+   change the window size in pixels--it can also change the size as measured in
+   rows and columns.
+
+ - (Aside: in the 14342 build, there is also a bug with wmic.exe.  Open a console
+   with more than 300 lines of screen buffer, then fill those lines with, e.g.,
+   dir /s.  Then run wmic.exe.  You won't be able to see the wmic.exe prompt.
+   If you query the screen buffer info somehow, you'll notice that the srWindow
+   is not contained within the dwSize.  This breaks winpty's scraping, because
+   it's invalid.)
+
+ - In build 14316, with the Japanese locale, with the 437 code page, attempting
+   to set the Consolas font instead sets the Terminal (raster) font.  It seems
+   to pick an appropriate vertical size.
+
+ - It seems necessary to specify "-family 0x36" for maximum reliability.
+   Setting the family to 0 almost always works, and specifying just -tt rarely
+   works.

+Introduction
+============
+
+The only specification I could find describing mouse input escape sequences
+was the /usr/share/doc/xterm/ctlseqs.txt.gz file installed on my Ubuntu
+machine.
+
+Here are the relevant escape sequences:
+
+ * [ON] CSI '?' M 'h'                   Enable mouse input mode M
+ * [OFF] CSI '?' M 'l'                  Disable mouse input mode M
+ * [EVT] CSI 'M' F X Y                  Mouse event (default or mode 1005)
+ * [EVT6] CSI '<' F ';' X ';' Y 'M'     Mouse event with mode 1006
+ * [EVT6] CSI '<' F ';' X ';' Y 'm'     Mouse event with mode 1006 (up)
+ * [EVT15] CSI F ';' X ';' Y 'M'        Mouse event with mode 1015
+
+The first batch of modes affect what events are reported:
+
+ * 9: Presses only (not as well-supported as the other modes)
+ * 1000: Presses and releases
+ * 1002: Presses, releases, and moves-while-pressed
+ * 1003: Presses, releases, and all moves
+
+The next batch of modes affect the encoding of the mouse events:
+
+ * 1005: The X and Y coordinates are UTF-8 codepoints rather than bytes.
+ * 1006: Use the EVT6 sequences instead of EVT
+ * 1015: Use the EVT15 sequence instead of EVT (aka URVXT-mode)
+
+Support for modes in existing terminals

+
+*a: Mode 1003 is handled the same way as 1002.
+*b: The coordinate wraps from 0xff to 0x00, then maxs out at 0x07.  I'm
+    guessing this behavior is a bug?  I'm using the Xubuntu 14.04
+    gnome-terminal.
+*z: These terminals have a bug where column 224 (and row 224, presumably)
+    yields a truncated escape sequence.  224 + 32 is 0, so it would normally
+    yield `CSI 'M' F '\0' Y`, but the '\0' is interpreted as a NUL-terminator.
+
+Problem 1: How do these flags work?
+===================================
+
+Terminals accept the OFF sequence with any of the input modes.  This makes
+little sense--there are two multi-value settings, not seven independent flags!
+
+All the terminals handle Granularity the same way.  ON-Granularity sets
+Granularity to the specified value, and OFF-Granularity sets Granularity to
+OFF.
+
+Terminals vary in how they handle the Encoding modes.  For example:
+
+ * xterm.  ON-Encoding sets Encoding.  OFF-Encoding with a non-active Encoding
+   has no effect.  OFF-Encoding otherwise resets Encoding to Default.
+
+ * mintty (tested 2.2.2), iTerm2 2.1.4, and jediterm.  ON-Encoding sets
+   Encoding.  OFF-Encoding resets Encoding to Default.
+
+ * Konsole (tested 2.13.2) seems to configure each encoding method
+   independently.  The effective Encoding is the first enabled encoding in this
+   list:
+    - Mode 1006
+    - Mode 1015
+    - Mode 1005
+    - Default
+
+ * gnome-terminal (tested 3.6.2) also configures each encoding method
+   independently.  The effective Encoding is the first enabled encoding in
+   this list:
+    - Mode 1006
+    - Mode 1015
+    - Default
+   Mode 1005 is not supported.
+

+
+Capturing the console output
+----------------------------
+
+Initial idea:
+
+In the agent, keep track of the remote terminal state for N lines of
+(window+history).  Also keep track of the terminal size.  Regularly poll for
+changes to the console screen buffer, then use some number of edits to bring
+the remote terminal into sync with the console.
+
+This idea seems to have trouble when a Unix terminal is resized.  When the
+server receives a resize notification, it can have a hard time figuring out
+what the terminal did.  Race conditions might also be a problem.
+
+The behavior of the terminal can be tricky:
+
+ - When the window is expanded by one line, does the terminal add a blank line
+   to the bottom or move a line from the history into the top?
+
+ - When the window is shrunk by one line, does the terminal delete the topmost
+   or the bottommost line?  Can it delete the line with the cursor?
+
+Some popular behaviors for expanding:
+ - [all] If there are no history lines, then add a line at the bottom.
+ - [konsole] Always add a line at the bottom.
+ - [putty,xterm,rxvt] Pull in a history line from the top.
+ - [g-t] I can't tell.  It seems to add a blank line, until the program writes
+   to stdout or until I click the scroll bar, then the output "snaps" back down,
+   pulling lines out of the history.  I thought I saw different behavior
+   between Ubuntu 10.10 and 11.10, so maybe GNOME 3 changed something.  Avoid
+   using "bash" to test this behavior because "bash" apparently always writes
+   the prompt after terminal resize.
+
+Some popular behaviors for shrinking:
+ - [konsole,putty,xterm,rxvt] If the line at the bottom is blank, then delete
+   it.  Otherwise, move the topmost line into history.
+ - [g-t] If the line at the bottom has not been touched, then delete it.
+   Otherwise, move the topmost line into history.
+
+(TODO: I need to test my theories about the terminal behavior better still.
+It's interesting to see how g-t handles clear differently than every other
+terminal.)
+
+There is an ANSI escape sequence (DSR) that sends the current cursor location
+to the terminal's input.  One idea I had was to use this code to figure out how
+the terminal had handled a resize.  I currently think this idea won't work due
+to race conditions.
+
+Newer idea:
+
+Keep track of the last N lines that have been sent to the remote terminal.
+Poll for changes to console output.  When the output changes, send just the
+changed content to the terminal.  In particular:
+ - Don't send a cursor position (CUP) code.  Instead, if the line that's 3
+   steps up from the latest line changes, send a relative cursor up (CUU)
+   code.  It's OK to send an absolute column number code (CHA).
+ - At least in general, don't try to send complete screenshots of the current
+   console window.
+
+The idea is that sending just the changes should have good behavior for streams
+of output, even when those streams modify the output (e.g. an archiver, or
+maybe a downloader/packager/wget).  I need to think about whether this works
+for full-screen programs (e.g. emacs, less, lynx, the above list of programs).
+
+I noticed that console programs don't typically modify the window or buffer
+coordinates.  edit.com is an exception.
+
+I tested the pager in native Python (more?), and I verified that ENTER and SPACE
+both paid no attention to the location of the console window within the screen
+buffer.  This makes sense -- why would they care?  The Cygwin less, on the other
+hand, does care.  If I scroll the window up, then Cygwin less will write to a
+position within the window.  I didn't really expect this behavior, but it
+doesn't seem to be a problem.
+
+Setting up a TestNetServer service
+----------------------------------
+
+First run the deploy.sh script to copy files into deploy.  Make sure
+TestNetServer.exe will run in a bare environment (no MinGW or Qt in the path).
+
+Install the Windows Server 2003 Resource Kit.  It will have two programs in it,
+instsrv and srvany.
+
+Run:
+
+  InstSrv TestNetServer <path-to-srvany>\srvany.exe
+
+This creates a service named "TestNetServer" that uses the Microsoft service
+wrapper.  To configure the new service to run TestNetServer, set a registry
+value:
+
+  [HKLM\SYSTEM\CurrentControlSet\Services\TestNetServer\Parameters]
+  Application=<full-path>\TestNetServer.exe
+
+Also see http://www.iopus.com/guides/srvany.htm.
+
+To remove the service, run:
+
+  InstSrv TestNetServer REMOVE
+
+TODO
+----
+
+Agent: When resizing the console, consider whether to add lines to the top
+or bottom.  I remember thinking the current behavior was wrong for some
+application, but I forgot which one.
+
+Make the font as small as possible.  The console window dimensions are limited by
+the screen size, so making the font small reduces an unnecessary limitation on the
+PseudoConsole size.  There's a documented Vista/Win7 API for this
+(SetCurrentConsoleFontEx), and apparently WinXP has an undocumented API
+(SetConsoleFont):
+    http://blogs.microsoft.co.il/blogs/pavely/archive/2009/07/23/changing-console-fonts.aspx
+
+Make the agent work with DOS programs like edit and qbasic.
+ - Detect that the terminal program has resized the window/buffer and enter a
+   simple just-scrape-and-dont-resize mode.  Track the client window size and
+   send the intersection of the console and the agent's client.
+ - I also need to generate keyboard scan codes.
+ - Solve the NTVDM.EXE console shutdown problem, probably by ignoring NTVDM.EXE
+   when it appears on the GetConsoleProcessList list.
+
+Rename the agent?  Is the term "proxy" more accurate?
+
+Optimize the polling.  e.g. Use a longer poll interval when the console is idle.
+Do a minimal poll that checks whether the sync marker or window has moved.
+
+Increase the console buffer size to ~9000 lines.  Beware making it so big that
+reading the sync column exhausts the 32KB conhost<->agent heap.
+
+Reduce the memory overhead of the agent.  The agent's m_bufferData array can
+be small (a few hundred lines?) relative to the console buffer size.
+
+Try to handle console background color better.
+    Unix terminal emulators have a user-configurable foreground and background
+color, and for best results, the agent really needs to avoid changing the colors,
+especially the background color.  It's undesirable/ugly to SSH into a machine
+and see the command prompt change the colors.  It's especially ugly that the
+terminal retains its original colors and only drawn cells get the new colors.
+(e.g. Resizing the window to the right uses the local terminal colors rather
+than the remote colors.)  It's especially ugly in gnome-terminal, which draws
+user-configurable black as black, but VT100 black as dark-gray.
+    If there were a way to query the terminal emulator's colors, then I could
+match the console's colors to the terminal and everything would just work.  As
+far as I know, that's not possible.
+    I thought of a kludge that might work.  Instead of translating console white
+and black to VT/100 white and black, I would translate them to "reset" and
+"invert".  I'd translate other colors normally.  This approach should produce
+ideal results for command-line work and tolerable results for full-screen
+programs without configuration.  Configuring the agent for black-on-white or
+white-on-black would produce ideal results in all situations.
+    This kludge only really applies to the SSH application.  For a Win32 Konsole
+application, it should be easy to get the colors right all the time.
+
+Try using the screen reader API:
+ - To eliminate polling.
+ - To detect when a line wraps.  When a line wraps, it'd be nice not to send a
+   CRLF to the terminal emulator so copy-and-paste works better.
+ - To detect hard tabs with Cygwin.
+
+Implement VT100/ANSI escape sequence recognition for input.  Decide where this
+functionality belongs.  PseudoConsole.dll?  Disambiguating ESC from an escape
+sequence might be tricky.  For the SSH server, I was thinking that when a small
+SSH payload ended with an ESC character, I could assume the character was really
+an ESC keypress, on the assumption that if it were an escape sequence, the
+payload would probably contain the whole sequence.  I'm not sure this works,
+especially if there's a lot of other traffic multiplexed on the SSH socket.
+
+Support Unicode.
+ - Some DOS programs draw using line/box characters.  Can these characters be
+   translated to the Unicode equivalents?
+
+Create automated tests.
+
+Experiment with the Terminator emulator, an emulator that doesn't wrap lines.
+How many columns does it report having?  What column does it report the cursor
+in as it's writing past the right end of the window?  Will Terminator be a
+problem if I implement line wrapping detection in the agent?
+
+BUG: After the unix-adapter/pconsole.exe program exits, the blinking cursor is
+replaced with a hidden cursor.
+
+Fix assert() in the agent.  If it fails, the failure message needs to be
+reported somewhere.  Pop up a dialog box?  Maybe switch the active desktop,
+then show a dialog box?
+
+TODO: There's already a pconsole project on GitHub.  Maybe rename this project
+to something else?  winpty?
+
+TODO: Can the DebugServer system be replaced with OutputDebugString?  How
+do we decide whose processes' output to collect?
+
+TODO: Three executables:
+  build/winpty-agent.exe
+  build/winpty.dll
+  build/console.exe
+
+BUG: Run the pconsole.exe inside another console.  As I type dir, I see this:
+      D:\rprichard\pconsole>
+      D:\rprichard\pconsole>d
+      D:\rprichard\pconsole>di
+      D:\rprichard\pconsole>dir
+    In the output of "dir", every other line is blank.
+    There was a bug in Terminal::sendLine that was causing this to happen
+    frequently.  Now that I fixed it, this bug should only manifest on lines
+    whose last column is not a space (i.e. a full line).

+Notes regarding fonts, code pages, and East Asian character widths
+==================================================================
+
+
+Registry settings
+=================
+
+ * There are console registry settings in `HKCU\Console`.  That key has many
+   default settings (e.g. the default font settings) and also per-app subkeys
+   for app-specific overrides.
+
+ * It is possible to override the code page with an app-specific setting.
+
+ * There are registry settings in
+   `HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console`.  In particular,
+   the `TrueTypeFont` subkey has a list of suitable font names associated with
+   various CJK code pages, as well as default font names.
+
+ * There are two values in `HKLM\SYSTEM\CurrentControlSet\Control\Nls\CodePage`
+   that specify the current code pages -- `OEMCP` and `ACP`.  Setting the
+   system locale via the Control Panel's "Region" or "Language" dialogs seems
+   to change these code page values.
+
+
+Console fonts
+=============
+
+ * The `FontFamily` field of `CONSOLE_FONT_INFOEX` has two parts:
+    - The high four bits can be exactly one of the `FF_xxxx` font families:
+          FF_DONTCARE(0x00)
+          FF_ROMAN(0x10)
+          FF_SWISS(0x20)
+          FF_MODERN(0x30)
+          FF_SCRIPT(0x40)
+          FF_DECORATIVE(0x50)
+    - The low four bits are a bitmask:
+          TMPF_FIXED_PITCH(1) -- actually means variable pitch
+          TMPF_VECTOR(2)
+          TMPF_TRUETYPE(4)
+          TMPF_DEVICE(8)
+
+ * Each console has its own independent console font table.  The current font
+   is identified with an index into this table.  The size of the table is
+   returned by the undocumented `GetNumberOfConsoleFonts` API.  It is apparently
+   possible to get the table size without this API, by instead calling
+   `GetConsoleFontSize` on each nonnegative index starting with 0 until the API
+   fails by returning (0, 0).
+
+ * The font table grows dynamically.  Each time the console is configured with
+   a previously-unused (FaceName, Size) combination, two entries are added to
+   the font table -- one with normal weight and one with bold weight.  Fonts
+   added this way are always TrueType fonts.
+
+ * Initially, the font table appears to contain only raster fonts.  For
+   example, on an English Windows 8 installation, here is the initial font
+   table:
+       font 0: 4x6
+       font 1: 6x8
+       font 2: 8x8
+       font 3: 16x8
+       font 4: 5x12
+       font 5: 7x12
+       font 6: 8x12 -- the current font
+       font 7: 16x12
+       font 8: 12x16
+       font 9: 10x18
+   `GetNumberOfConsoleFonts` returns 10, and this table matches the raster font
+   sizes according to the console properties dialog.
+
+ * With a Japanese or Chinese locale, the initial font table appears to contain
+   the sizes applicable to both the East Asian raster font, as well as the
+   sizes for the CP437/CP1252 raster font.
+
+ * The index passed to `SetCurrentConsoleFontEx` apparently has no effect.
+   The undocumented `SetConsoleFont` API, however, accepts *only* a font index,
+   and on Windows 8 English, it switches between all 10 fonts, even font index
+   #0.
+
+ * If the index passed to `SetConsoleFont` identifies a Raster Font
+   incompatible with the current code page, then another Raster Font is
+   activated.
+
+ * Passing "Terminal" to `SetCurrentConsoleFontEx` seems to have no effect.
+   Perhaps relatedly, `SetCurrentConsoleFontEx` does not fail if it is given a
+   bogus `FaceName`.  Some font is still chosen and activated.  Passing a face
+   name and height seems to work reliably, modulo the CP936 issue described
+   below.
+
+
+Console fonts and code pages
+============================
+
+ * On an English Windows installation, the default code page is 437, and it
+   cannot be set to 932 (Shift-JIS).  (The API call fails.)  Changing the
+   system locale to "Japanese (Japan)" using the Region/Language dialog
+   changes the default CP to 932 and permits changing the console CP between
+   437 and 932.
+
+ * A console has both an input code page and an output code page
+   (`{Get,Set}ConsoleCP` and `{Get,Set}ConsoleOutputCP`).  I'm not going to
+   distinguish between the two for this document; presumably only the output
+   CP matters.  The code page can change while the console is open, e.g.
+   by running `mode con: cp select={932,437,1252}` or by calling
+   `SetConsoleOutputCP`.
+
+ * The current code page restricts which TrueType fonts and which Raster Font
+   sizes are available in the console properties dialog.  This can change
+   while the console is open.
+
+ * Changing the code page almost(?) always changes the current console font.
+   So far, I don't know how the new font is chosen.
+
+ * With a CP of 932, the only TrueType font available in the console properties
+   dialog is "MS Gothic", displayed as "ＭＳ ゴシック".  It is still possible to
+   use the English-default TrueType console fonts, Lucida Console and Consolas,
+   via `SetCurrentConsoleFontEx`.
+
+ * When using a Raster Font and CP437 or CP1252, writing a UTF-16 codepoint not
+   representable in the code page instead writes a question mark ('?') to the
+   console.  This conversion does not apply with a TrueType font, nor with the
+   Raster Font for CP932 or CP936.
+
+
+ReadConsoleOutput and double-width characters
+==============================================
+
+ * With a Raster Font active, when `ReadConsoleOutputW` reads two cells of a
+   double-width character, it fills only a single `CHAR_INFO` structure.  The
+   unused trailing `CHAR_INFO` structures are zero-filled.  With a TrueType
+   font active, `ReadConsoleOutputW` instead fills two `CHAR_INFO` structures,
+   the first marked with `COMMON_LVB_LEADING_BYTE` and the second marked with
+   `COMMON_LVB_TRAILING_BYTE`.  The flag is a misnomer--there aren't two
+   *bytes*, but two cells, and they have equal `CHAR_INFO.Char.UnicodeChar`
+   values.
+
+ * `ReadConsoleOutputA`, on the other hand, reads two `CHAR_INFO` cells, and
+   if the UTF-16 value can be represented as two bytes in the ANSI/OEM CP, then
+   the two bytes are placed in the two `CHAR_INFO.Char.AsciiChar` values, and
+   the `COMMON_LVB_{LEADING,TRAILING}_BYTE` values are also used.  If the
+   codepoint isn't representable, I don't remember what happens -- I think the
+   `AsciiChar` values take on an invalid marker.
+
+ * Reading only one cell of a double-width character reads a space (U+0020)
+   instead.  Raster-vs-TrueType and wide-vs-ANSI do not matter.
+    - XXX: what about attributes?  Can a double-width character have mismatched
+      color attributes?
+    - XXX: what happens when writing to just one cell of a double-width
+      character?
+
+
+Default Windows fonts for East Asian languages
+==============================================
+CP932 / Japanese: "ＭＳ ゴシック" (MS Gothic)
+CP936 / Chinese Simplified: "新宋体" (SimSun)
+
+
+Unreliable character width (half-width vs full-width)
+=====================================================
+
+The half-width vs full-width status of a codepoint depends on at least these variables:
+ * OS version (Win10 legacy and new modes are different versions)
+ * system locale (English vs Japanese vs Chinese Simplified vs Chinese Traditional, etc)
+ * code page (437 vs 932 vs 936, etc)
+ * raster vs TrueType (Terminal vs MS Gothic vs SimSun, etc)
+ * font size
+ * rendered-vs-model (rendered width can be larger or smaller than model width)

+
+Windows quirk: unreliable font heights with CP936 / Chinese Simplified
+======================================================================
+
+When I set the font to 新宋体 17px, using either the properties dialog or
+`SetCurrentConsoleFontEx`, the height reported by `GetCurrentConsoleFontEx` is
+not 17, but is instead 19.  The same problem does not affect Raster Fonts,
+nor have I seen the problem in the English or Japanese locales.  I observed
+this with Windows 7 and Windows 10 new mode.
+
+If I set the font using the facename, width, *and* height, then the
+`SetCurrentConsoleFontEx` and `GetCurrentConsoleFontEx` values agree.  If I
+set the font using *only* the facename and height, then the two values
+disagree.
+
+
+Windows bug: GetCurrentConsoleFontEx is initially invalid
+=========================================================
+
+ - Assume there is no configured console font name in the registry.  In this
+   case, the console defaults to a raster font.
+ - Open a new console and call the `GetCurrentConsoleFontEx` API.
+ - The `FaceName` field of the returned `CONSOLE_FONT_INFOEX` data
+   structure is incorrect.  On Windows 7, 8, and 10, I observed that the
+   field was blank.  On Windows 8, occasionally, it instead contained:
+      U+AE72 U+75BE U+0001
+   The other fields of the structure all appeared correct:
+      nFont=6 dwFontSize=(8,12) FontFamily=0x30 FontWeight=400
+ - The `FaceName` field becomes initialized easily:
+    - Open the console properties dialog and click OK.  (Cancel is not
+      sufficient.)
+    - Call the undocumented `SetConsoleFont` with the current font table
+      index, which is 6 in the example above.
+ - It seems that the console uncritically accepts whatever string is
+   stored in the registry, including a blank string, and passes it on the
+   the `GetCurrentConsoleFontEx` caller.  It is possible to get the console
+   to *write* a blank setting into the registry -- simply open the console
+   (default or app-specific) properties and click OK.

+
+        ...
+
+    The U+3044 character (HIRAGANA LETTER I) occupies two columns, but it only
+    fills one record in the ReadConsoleOutput output buffer, which has the
+    effect of shifting the first cell of the second row into the last cell of
+    the first row.  Ordinarily, the first and second cells would also have the
+    COMMON_LVB_LEADING_BYTE and COMMON_LVB_TRAILING_BYTE attributes set, which
+    allows winpty to detect the double-column character.
+
+Case 2:
+
+    > chcp 437
+    > winbug-15048 -face "Lucida Console" -h 4 221A
+
+    The same issue happens with U+221A (SQUARE ROOT), but only in certain
+    fonts.  The console seems to think this character occupies two columns
+    if the font is sufficiently small.  The Windows console properties dialog
+    doesn't allow fonts below 5 pt, but winpty tries to use 2pt and 4pt Lucida
+    Console to allow very large console windows.
+
+Case 3:
+
+    > chcp 437
+    > winbug-15048 -face "Lucida Console" -h 12 FF12
+
+    The console selection system thinks U+FF12 (FULLWIDTH DIGIT TWO) occupies
+    two columns, which happens to be correct, but it's displayed as a single
+    column unrecognized character.  It otherwise behaves the same as the other
+    cases.

+// Windows does not correctly identify code points as double-width in all

+// and (somehow) even the font size.  In the 437 code page (MS-DOS), for
+// example, no codepoints are interpreted as double-width.  When the console
+// is in an East Asian code page (932, 936, 949, or 950), then sometimes
+// selecting a "Western" facename like "Lucida Console" or "Consolas" doesn't
+// register, or if the font *can* be chosen, then the console doesn't handle
+// double-width correctly.  I tested the double-width handling by writing
+// several code points with WriteConsole and checking whether one or two cells
+// were filled.
+//
+// In the Japanese code page (932), Microsoft's default font is MS Gothic.

+// especially broken in Windows 8 and 8.1.

+// Test by running: misc/Utf16Echo A2 A3 2014 3044 30FC 4000
+//
+// The first three codepoints are always rendered as half-width with the
+// Windows Japanese fonts.  (Of these, the first two must be half-width,
+// but U+2014 could be either.)  The last three are rendered as full-width,
+// and they are East_Asian_Width=Wide.
+//
+// Windows 7 fails by modeling all codepoints as full-width with font
+// sizes 22 and above.
+//
+// Windows 8 gets U+00A2, U+00A3, U+2014, U+30FC, and U+4000 wrong, but
+// using a point size not listed in the console properties dialog
+// (e.g. "9") is less wrong:

+    // Windows apparently handles everything outside of the keyboard layout by
+    // first sending a sequence of Alt+KeyPad events, then finally a key-up
+    // event whose UnicodeChar has the appropriate value.  For U+00A2 (CENT
+    // SIGN):
+    //
+    //      key: dn rpt=1 scn=56 LAlt-MENU ch=0
+    //      key: dn rpt=1 scn=79 LAlt-NUMPAD1 ch=0
+    //      key: up rpt=1 scn=79 LAlt-NUMPAD1 ch=0
+    //      key: dn rpt=1 scn=76 LAlt-NUMPAD5 ch=0
+    //      key: up rpt=1 scn=76 LAlt-NUMPAD5 ch=0

+    //      key: up rpt=1 scn=56 MENU ch=0xa2
+    //
+    // The Alt+155 value matches the encoding of U+00A2 in CP-437.  Curiously,
+    // if I use "chcp 1252" to change the encoding, then copy-and-pasting
+    // produces Alt+162 instead.  (U+00A2 is 162 in CP-1252.)  However, typing
+    // Alt+155 or Alt+162 produce the same characters regardless of console
+    // code page.  (That is, they use CP-437 and yield U+00A2 and U+00F3.)
+    //
+    // For characters outside the BMP, Windows repeats the process for both
+    // UTF-16 code units, e.g, for U+1F300 (CYCLONE):
+    //
+    //      key: dn rpt=1 scn=56 LAlt-MENU ch=0
+    //      key: dn rpt=1 scn=77 LAlt-NUMPAD6 ch=0
+    //      key: up rpt=1 scn=77 LAlt-NUMPAD6 ch=0
+    //      key: dn rpt=1 scn=81 LAlt-NUMPAD3 ch=0
+    //      key: up rpt=1 scn=81 LAlt-NUMPAD3 ch=0
+    //      key: up rpt=1 scn=56 MENU ch=0xd83c
+    //      key: dn rpt=1 scn=56 LAlt-MENU ch=0
+    //      key: dn rpt=1 scn=77 LAlt-NUMPAD6 ch=0
+    //      key: up rpt=1 scn=77 LAlt-NUMPAD6 ch=0

+    //      key: up rpt=1 scn=56 MENU ch=0xdf00
+    //
+    // In this case, it sends Alt+63 twice, which signifies '?'.  Apparently
+    // CMD and Cygwin bash are both able to decode this.
+    //
+    // Also note that typing Alt+NNN still works if NumLock is off, e.g.:
+    //
+    //      key: dn rpt=1 scn=56 LAlt-MENU ch=0
+    //      key: dn rpt=1 scn=79 LAlt-END ch=0

+
+Thanks to the crazy changes in V8 (and some in Node core), keeping native addons compiling happily across versions, particularly 0.10 to 0.12 to 4.0, is a minor nightmare. The goal of this project is to store all logic necessary to develop native Node.js addons without having to inspect `NODE_MODULE_VERSION` and get yourself into a macro-tangle.
+
+This project also contains some helper utilities that make addon development a bit more pleasant.

+## News & Updates
+
+<a name="usage"></a>
+
+## Usage
+
+Simply add **NAN** as a dependency in the *package.json* of your Node addon:
+
+``` bash
+$ npm install --save nan
+```
+
+Pull in the path to **NAN** in your *binding.gyp* so that you can use `#include <nan.h>` in your *.cpp* files:
+
+``` python
+"include_dirs" : [
+    "<!(node -e \"require('nan')\")"
+]
+```
+
+This works like a `-I<path-to-NAN>` when compiling your addon.
+
+<a name="example"></a>
+
+## Example
+
+Just getting started with Nan? Take a look at the **[Node Add-on Examples](https://github.com/nodejs/node-addon-examples)**.
+
+Refer to a [quick-start **Nan** Boilerplate](https://github.com/fcanas/node-native-boilerplate) for a ready-to-go project that utilizes basic Nan functionality.
+
+For a simpler example, see the **[async pi estimation example](https://github.com/nodejs/nan/tree/master/examples/async_pi_estimate)** in the examples directory for full code and an explanation of what this Monte Carlo Pi estimation example does. Below are just some parts of the full example that illustrate the use of **NAN**.
+
+Yet another example is **[nan-example-eol](https://github.com/CodeCharmLtd/nan-example-eol)**. It shows newline detection implemented as a native addon.
+
+Also take a look at our comprehensive **[C++ test suite](https://github.com/nodejs/nan/tree/master/test/cpp)** which has a plethora of code snippets for your pasting pleasure.

+
+### JavaScript-accessible methods
+
+A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information.
+
+In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

+
+### Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="doc/scopes.md#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="doc/scopes.md#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection).
+
+### Persistent references
+
+An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
+
+Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://developers.google.com/v8/embed#handles).
+
+### New
+
+NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8.
+
+ - <a href="doc/new.md#api_nan_new"><b><code>Nan::New()</code></b></a>

+ - <a href="doc/new.md#api_nan_false"><b><code>Nan::False()</code></b></a>
+ - <a href="doc/new.md#api_nan_empty_string"><b><code>Nan::EmptyString()</code></b></a>
+
+
+### Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.
+
+ - <a href="doc/converters.md#api_nan_to"><b><code>Nan::To()</code></b></a>
+
+### Maybe Types
+
+The `Nan::MaybeLocal` and `Nan::Maybe` types are monads that encapsulate `v8::Local` handles that _may be empty_.

+### Script
+
+NAN provides a `v8::Script` helpers as the API has changed over the supported versions of V8.

+ - <a href="doc/script.md#api_nan_compile_script"><b><code>Nan::CompileScript()</code></b></a>
+ - <a href="doc/script.md#api_nan_run_script"><b><code>Nan::RunScript()</code></b></a>
+
+
+### JSON
+
+The _JSON_ object provides the C++ versions of the methods offered by the `JSON` object in javascript. V8 exposes these methods via the `v8::JSON` object.
+
+ - <a href="doc/json.md#api_nan_json_parse"><b><code>Nan::JSON.Parse</code></b></a>
+ - <a href="doc/json.md#api_nan_json_stringify"><b><code>Nan::JSON.Stringify</code></b></a>
+
+Refer to the V8 JSON object in the [V8 documentation](https://v8docs.nodesource.com/node-8.16/da/d6f/classv8_1_1_j_s_o_n.html) for more information about these methods and their arguments.
+
+### Errors
+
+NAN includes helpers for creating, throwing and catching Errors as much of this functionality varies across the supported versions of V8 and must be abstracted.
+
+Note that an Error object is simply a specialized form of `v8::Value`.
+
+Also consult the V8 Embedders Guide section on [Exceptions](https://developers.google.com/v8/embed#exceptions) for more information.

+
+
+### Buffers
+
+NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.

+ - <a href="doc/buffers.md#api_nan_free_callback"><b><code>Nan::FreeCallback()</code></b></a>
+
+### Nan::Callback
+
+`Nan::Callback` makes it easier to use `v8::Function` handles as callbacks. A class that wraps a `v8::Function` handle, protecting it from garbage collection and making it particularly useful for storage and use across asynchronous execution.
+
+ - <a href="doc/callback.md#api_nan_callback"><b><code>Nan::Callback</code></b></a>
+
+### Asynchronous work helpers
+
+`Nan::AsyncWorker`, `Nan::AsyncProgressWorker` and `Nan::AsyncProgressQueueWorker` are helper classes that make working with asynchronous code easier.

+
+### Strings & Bytes
+
+Miscellaneous string & byte encoding and decoding functionality provided for compatibility across supported versions of V8 and Node. Implemented by NAN to ensure that all encoding types are supported, even for older versions of Node where they are missing.

+
+
+### V8 internals
+
+The hooks to access V8 internals—including GC and statistics—are different across the supported versions of V8, therefore NAN provides its own hooks that call the appropriate V8 methods.

+## Known issues
+
+### Compiling against Node.js 0.12 on OSX
+
+With new enough compilers available on OSX, the versions of V8 headers corresponding to Node.js 0.12
+do not compile anymore. The error looks something like:
+
+```
+❯   CXX(target) Release/obj.target/accessors/cpp/accessors.o
+In file included from ../cpp/accessors.cpp:9:
+In file included from ../../nan.h:51:
+In file included from /Users/ofrobots/.node-gyp/0.12.18/include/node/node.h:61:
+/Users/ofrobots/.node-gyp/0.12.18/include/node/v8.h:5800:54: error: 'CreateHandle' is a protected member of 'v8::HandleScope'
+  return Handle<T>(reinterpret_cast<T*>(HandleScope::CreateHandle(
+                                        ~~~~~~~~~~~~~^~~~~~~~~~~~
+```
+
+This can be worked around by patching your local versions of v8.h corresponding to Node 0.12 to make
+`v8::Handle` a friend of `v8::HandleScope`. Since neither Node.js not V8 support this release line anymore
+this patch cannot be released by either project in an official release.
+
+For this reason, we do not test against Node.js 0.12 on OSX in this project's CI. If you need to support
+that configuration, you will need to either get an older compiler, or apply a source patch to the version
+of V8 headers as a workaround.

+NAN is governed by the [Node.js Addon API Working Group](https://github.com/nodejs/CTC/blob/master/WORKING_GROUPS.md#addon-api)
+
+### Addon API Working Group (WG)
+
+The NAN project is jointly governed by a Working Group which is responsible for high-level guidance of the project.
+
+Members of the WG are also known as Collaborators, there is no distinction between the two, unlike other Node.js projects.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project [README.md](./README.md#collaborators).
+
+Individuals making significant and valuable contributions are made members of the WG and given commit-access to the project. These individuals are identified by the WG and their addition to the WG is discussed via GitHub and requires unanimous consensus amongst those WG members participating in the discussion with a quorum of 50% of WG members required for acceptance of the vote.
+
+_Note:_ If you make a significant contribution and are not considered for commit-access log an issue or contact a WG member directly.
+
+For the current list of WG members / Collaborators, see the project [README.md](./README.md#collaborators).
+
+### Consensus Seeking Process
+
+The WG follows a [Consensus Seeking](https://en.wikipedia.org/wiki/Consensus-seeking_decision-making) decision making model.
+
+Modifications of the contents of the NAN repository are made on a collaborative basis. Anybody with a GitHub account may propose a modification via pull request and it will be considered by the WG. All pull requests must be reviewed and accepted by a WG member with sufficient expertise who is able to take full responsibility for the change. In the case of pull requests proposed by an existing WG member, an additional WG member is required for sign-off. Consensus should be sought if additional WG members participate and there is disagreement around a particular modification.
+
+If a change proposal cannot reach a consensus, a WG member can call for a vote amongst the members of the WG. Simple majority wins.

+## Asynchronous work helpers
+
+`Nan::AsyncWorker`, `Nan::AsyncProgressWorker` and `Nan::AsyncProgressQueueWorker` are helper classes that make working with asynchronous code easier.

+### Nan::AsyncWorker
+
+`Nan::AsyncWorker` is an _abstract_ class that you can subclass to have much of the annoying asynchronous queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the asynchronous work is in progress.
+
+This class internally handles the details of creating an [`AsyncResource`][AsyncResource], and running the callback in the
+correct async context. To be able to identify the async resources created by this class in async-hooks, provide a
+`resource_name` to the constructor. It is recommended that the module name be used as a prefix to the `resource_name` to avoid
+collisions in the names. For more details see [`AsyncResource`][AsyncResource] documentation.  The `resource_name` needs to stay valid for the lifetime of the worker instance.
+
+Definition:
+
+```c++
+class AsyncWorker {
+ public:
+  explicit AsyncWorker(Callback *callback_, const char* resource_name = "nan:AsyncWorker");
+
+  virtual ~AsyncWorker();
+
+  virtual void WorkComplete();
+
+  void SaveToPersistent(const char *key, const v8::Local<v8::Value> &value);
+
+  void SaveToPersistent(const v8::Local<v8::String> &key,
+                        const v8::Local<v8::Value> &value);
+
+  void SaveToPersistent(uint32_t index,
+                        const v8::Local<v8::Value> &value);
+
+  v8::Local<v8::Value> GetFromPersistent(const char *key) const;
+
+  v8::Local<v8::Value> GetFromPersistent(const v8::Local<v8::String> &key) const;
+
+  v8::Local<v8::Value> GetFromPersistent(uint32_t index) const;
+
+  virtual void Execute() = 0;
+
+  uv_work_t request;
+
+  virtual void Destroy();
+
+ protected:
+  Persistent<v8::Object> persistentHandle;
+
+  Callback *callback;
+
+  virtual void HandleOKCallback();
+
+  virtual void HandleErrorCallback();
+
+  void SetErrorMessage(const char *msg);
+
+  const char* ErrorMessage();
+};
+```
+
+<a name="api_nan_async_progress_worker"></a>
+### Nan::AsyncProgressWorkerBase &amp; Nan::AsyncProgressWorker
+
+`Nan::AsyncProgressWorkerBase` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
+
+Previously the definition of `Nan::AsyncProgressWorker` only allowed sending `const char` data. Now extending `Nan::AsyncProgressWorker` will yield an instance of the implicit `Nan::AsyncProgressWorkerBase` template with type `<char>` for compatibility.
+
+`Nan::AsyncProgressWorkerBase` &amp; `Nan::AsyncProgressWorker` is intended for best-effort delivery of nonessential progress messages, e.g. a progress bar.  The last event sent before the main thread is woken will be delivered.
+
+Definition:
+
+```c++
+template<class T>
+class AsyncProgressWorkerBase<T> : public AsyncWorker {
+ public:
+  explicit AsyncProgressWorkerBase(Callback *callback_, const char* resource_name = ...);
+
+  virtual ~AsyncProgressWorkerBase();
+
+  void WorkProgress();
+
+  class ExecutionProgress {
+   public:
+    void Signal() const;
+    void Send(const T* data, size_t count) const;
+  };
+
+  virtual void Execute(const ExecutionProgress& progress) = 0;
+
+  virtual void HandleProgressCallback(const T *data, size_t count) = 0;
+
+  virtual void Destroy();
+};
+
+typedef AsyncProgressWorkerBase<T> AsyncProgressWorker;
+```
+
+<a name="api_nan_async_progress_queue_worker"></a>
+### Nan::AsyncProgressQueueWorker
+
+`Nan::AsyncProgressQueueWorker` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
+
+`Nan::AsyncProgressQueueWorker` behaves exactly the same as `Nan::AsyncProgressWorker`, except all events are queued and delivered to the main thread.
+
+Definition:
+
+```c++
+template<class T>
+class AsyncProgressQueueWorker<T> : public AsyncWorker {
+ public:
+  explicit AsyncProgressQueueWorker(Callback *callback_, const char* resource_name = "nan:AsyncProgressQueueWorker");
+
+  virtual ~AsyncProgressQueueWorker();
+
+  void WorkProgress();
+
+  class ExecutionProgress {
+   public:
+    void Send(const T* data, size_t count) const;
+  };
+
+  virtual void Execute(const ExecutionProgress& progress) = 0;
+
+  virtual void HandleProgressCallback(const T *data, size_t count) = 0;
+
+  virtual void Destroy();
+};
+```
+
+<a name="api_nan_async_queue_worker"></a>
+### Nan::AsyncQueueWorker
+
+`Nan::AsyncQueueWorker` will run a `Nan::AsyncWorker` asynchronously via libuv. Both the `execute` and `after_work` steps are taken care of for you. Most of the logic for this is embedded in `Nan::AsyncWorker`.
+
+Definition:
+

+## Buffers
+
+NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.

+
+<a name="api_nan_new_buffer"></a>
+### Nan::NewBuffer()
+
+Allocate a new `node::Buffer` object with the specified size and optional data. Calls `node::Buffer::New()`.
+
+Note that when creating a `Buffer` using `Nan::NewBuffer()` and an existing `char*`, it is assumed that the ownership of the pointer is being transferred to the new `Buffer` for management.
+When a `node::Buffer` instance is garbage collected and a `FreeCallback` has not been specified, `data` will be disposed of via a call to `free()`.
+You _must not_ free the memory space manually once you have created a `Buffer` in this way.

+### Nan::CopyBuffer()
+
+Similar to [`Nan::NewBuffer()`](#api_nan_new_buffer) except that an implicit memcpy will occur within Node. Calls `node::Buffer::Copy()`.
+
+Management of the `char*` is left to the user, you should manually free the memory space if necessary as the new `Buffer` will have its own copy.

+### Nan::FreeCallback()
+
+A free callback that can be provided to [`Nan::NewBuffer()`](#api_nan_new_buffer).
+The supplied callback will be invoked when the `Buffer` undergoes garbage collection.
+
+Signature:
+
+```c++
+typedef void (*FreeCallback)(char *data, void *hint);

+## Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.

+## JSON
+
+The _JSON_ object provides the c++ versions of the methods offered by the `JSON` object in javascript. V8 exposes these methods via the `v8::JSON` object.
+
+ - <a href="#api_nan_json_parse"><b><code>Nan::JSON.Parse</code></b></a>
+ - <a href="#api_nan_json_stringify"><b><code>Nan::JSON.Stringify</code></b></a>
+
+Refer to the V8 JSON object in the [V8 documentation](https://v8docs.nodesource.com/node-8.16/da/d6f/classv8_1_1_j_s_o_n.html) for more information about these methods and their arguments.

+
+Definition:
+
+```c++
+Nan::MaybeLocal<v8::Value> Nan::JSON::Parse(v8::Local<v8::String> json_string);
+```
+
+Use `JSON.Parse(json_string)` to parse a string into a `v8::Value`.
+
+Example:
+
+```c++
+v8::Local<v8::String> json_string = Nan::New("{ \"JSON\": \"object\" }").ToLocalChecked();
+
+Nan::JSON NanJSON;
+Nan::MaybeLocal<v8::Value> result = NanJSON.Parse(json_string);

+### Nan::MaybeLocal
+
+A `Nan::MaybeLocal<T>` is a wrapper around [`v8::Local<T>`](https://v8docs.nodesource.com/node-8.16/de/deb/classv8_1_1_local.html) that enforces a check that determines whether the `v8::Local<T>` is empty before it can be used.
+
+If an API method returns a `Nan::MaybeLocal`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, an empty `Nan::MaybeLocal` is returned.
+
+Definition:
+
+```c++
+template<typename T> class Nan::MaybeLocal {
+ public:
+  MaybeLocal();
+
+  template<typename S> MaybeLocal(v8::Local<S> that);
+
+  bool IsEmpty() const;
+
+  template<typename S> bool ToLocal(v8::Local<S> *out);
+
+  // Will crash if the MaybeLocal<> is empty.
+  v8::Local<T> ToLocalChecked();
+
+  template<typename S> v8::Local<S> FromMaybe(v8::Local<S> default_value) const;
+};
+```
+
+See the documentation for [`v8::MaybeLocal`](https://v8docs.nodesource.com/node-8.16/d8/d7d/classv8_1_1_maybe_local.html) for further details.
+
+<a name="api_nan_maybe"></a>
+### Nan::Maybe
+
+A simple `Nan::Maybe` type, representing an object which may or may not have a value, see https://hackage.haskell.org/package/base/docs/Data-Maybe.html.
+
+If an API method returns a `Nan::Maybe<>`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, a "Nothing" value is returned.
+
+Definition:
+
+```c++
+template<typename T> class Nan::Maybe {
+ public:
+  bool IsNothing() const;
+  bool IsJust() const;
+
+  // Will crash if the Maybe<> is nothing.
+  T FromJust();
+
+  T FromMaybe(const T& default_value);
+
+  bool operator==(const Maybe &other);
+
+  bool operator!=(const Maybe &other);
+};

+## JavaScript-accessible methods
+
+A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information.
+
+In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

+### Nan::FunctionCallbackInfo
+
+`Nan::FunctionCallbackInfo` should be used in place of [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/node-8.16/dd/d0d/classv8_1_1_function_callback_info.html), even with older versions of Node where `v8::FunctionCallbackInfo` does not exist.
+
+Definition:
+
+```c++
+template<typename T> class FunctionCallbackInfo {
+ public:
+  ReturnValue<T> GetReturnValue() const;
+  v8::Local<v8::Function> Callee(); // NOTE: Not available in NodeJS >= 10.0.0
+  v8::Local<v8::Value> Data();
+  v8::Local<v8::Object> Holder();
+  bool IsConstructCall();
+  int Length() const;
+  v8::Local<v8::Value> operator[](int i) const;
+  v8::Local<v8::Object> This() const;
+  v8::Isolate *GetIsolate() const;
+};
+```
+
+See the [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/node-8.16/dd/d0d/classv8_1_1_function_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from methods.
+
+**Note:** `FunctionCallbackInfo::Callee` is removed in Node.js after `10.0.0` because it is was deprecated in V8. Consider using `info.Data()` to pass any information you need.
+
+<a name="api_nan_property_callback_info"></a>
+### Nan::PropertyCallbackInfo
+
+`Nan::PropertyCallbackInfo` should be used in place of [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d7/dc5/classv8_1_1_property_callback_info.html), even with older versions of Node where `v8::PropertyCallbackInfo` does not exist.
+
+Definition:
+
+```c++
+template<typename T> class PropertyCallbackInfo : public PropertyCallbackInfoBase<T> {
+ public:
+  ReturnValue<T> GetReturnValue() const;
+  v8::Isolate* GetIsolate() const;
+  v8::Local<v8::Value> Data() const;
+  v8::Local<v8::Object> This() const;
+  v8::Local<v8::Object> Holder() const;
+};
+```
+
+See the [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d7/dc5/classv8_1_1_property_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from property accessor methods.
+
+<a name="api_nan_return_value"></a>
+### Nan::ReturnValue
+
+`Nan::ReturnValue` is used in place of [`v8::ReturnValue`](https://v8docs.nodesource.com/node-8.16/da/da7/classv8_1_1_return_value.html) on both [`Nan::FunctionCallbackInfo`](#api_nan_function_callback_info) and [`Nan::PropertyCallbackInfo`](#api_nan_property_callback_info) as the return type of `GetReturnValue()`.
+
+Example usage:
+
+```c++
+void EmptyArray(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  info.GetReturnValue().Set(Nan::New<v8::Array>());
+}
+```
+
+Definition:
+
+```c++
+template<typename T> class ReturnValue {
+ public:
+  // Handle setters
+  template <typename S> void Set(const v8::Local<S> &handle);
+  template <typename S> void Set(const Nan::Global<S> &handle);
+
+  // Fast primitive setters
+  void Set(bool value);
+  void Set(double i);
+  void Set(int32_t i);
+  void Set(uint32_t i);
+
+  // Fast JS primitive setters
+  void SetNull();
+  void SetUndefined();
+  void SetEmptyString();
+
+  // Convenience getter for isolate
+  v8::Isolate *GetIsolate() const;
+};
+```
+
+See the documentation on [`v8::ReturnValue`](https://v8docs.nodesource.com/node-8.16/da/da7/classv8_1_1_return_value.html) for further information on this.
+
+<a name="api_nan_method"></a>
+### Method declaration
+
+JavaScript-accessible methods should be declared with the following signature to form a `Nan::FunctionCallback`:
+
+```c++
+typedef void(*FunctionCallback)(const FunctionCallbackInfo<v8::Value>&);
+```
+
+Example:

+
+<a name="api_nan_new"></a>
+### Nan::New()
+
+`Nan::New()` should be used to instantiate new JavaScript objects.
+
+Refer to the specific V8 type in the [V8 documentation](https://v8docs.nodesource.com/node-8.16/d1/d83/classv8_1_1_data.html) for information on the types of arguments required for instantiation.
+
+Signatures:
+
+Return types are mostly omitted from the signatures for simplicity. In most cases the type will be contained within a `v8::Local<T>`. The following types will be contained within a `Nan::MaybeLocal<T>`: `v8::String`, `v8::Date`, `v8::RegExp`, `v8::Script`, `v8::UnboundScript`.
+
+Empty objects:
+
+```c++
+Nan::New<T>();
+```
+
+Generic single and multiple-argument:
+
+```c++
+Nan::New<T>(A0 arg0);
+Nan::New<T>(A0 arg0, A1 arg1);
+Nan::New<T>(A0 arg0, A1 arg1, A2 arg2);
+Nan::New<T>(A0 arg0, A1 arg1, A2 arg2, A3 arg3);
+```
+
+For creating `v8::FunctionTemplate` and `v8::Function` objects:
+
+_The definition of `Nan::FunctionCallback` can be found in the [Method declaration](./methods.md#api_nan_method) documentation._
+
+```c++
+Nan::New<T>(Nan::FunctionCallback callback,
+            v8::Local<v8::Value> data = v8::Local<v8::Value>());
+Nan::New<T>(Nan::FunctionCallback callback,
+            v8::Local<v8::Value> data = v8::Local<v8::Value>(),
+            A2 a2 = A2());
+```
+
+Native number types:
+
+```c++
+v8::Local<v8::Boolean> Nan::New<T>(bool value);
+v8::Local<v8::Int32> Nan::New<T>(int32_t value);
+v8::Local<v8::Uint32> Nan::New<T>(uint32_t value);
+v8::Local<v8::Number> Nan::New<T>(double value);
+```
+
+String types:
+
+```c++
+Nan::MaybeLocal<v8::String> Nan::New<T>(std::string const& value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const char * value, int length);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const char * value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const uint16_t * value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const uint16_t * value, int length);
+```
+
+Specialized types:
+
+```c++
+v8::Local<v8::String> Nan::New<T>(v8::String::ExternalStringResource * value);
+v8::Local<v8::String> Nan::New<T>(Nan::ExternalOneByteStringResource * value);
+v8::Local<v8::RegExp> Nan::New<T>(v8::Local<v8::String> pattern, v8::RegExp::Flags flags);
+```
+
+Note that `Nan::ExternalOneByteStringResource` maps to [`v8::String::ExternalOneByteStringResource`](https://v8docs.nodesource.com/node-8.16/d9/db3/classv8_1_1_string_1_1_external_one_byte_string_resource.html), and `v8::String::ExternalAsciiStringResource` in older versions of V8.

+
+<a name="api_nan_asyncresource"></a>
+### Nan::AsyncResource
+
+This class is analogous to the `AsyncResource` JavaScript class exposed by Node's [async_hooks][] API.
+
+When calling back into JavaScript asynchronously, special care must be taken to ensure that the runtime can properly track
+async hops. `Nan::AsyncResource` is a class that provides an RAII wrapper around `node::EmitAsyncInit`, `node::EmitAsyncDestroy`,
+and `node::MakeCallback`. Using this mechanism to call back into JavaScript, as opposed to `Nan::MakeCallback` or
+`v8::Function::Call` ensures that the callback is executed in the correct async context. This ensures that async mechanisms
+such as domains and [async_hooks][] function correctly.
+
+Definition:
+
+```c++
+class AsyncResource {
+ public:
+  AsyncResource(v8::Local<v8::String> name,
+                v8::Local<v8::Object> resource = New<v8::Object>());
+  AsyncResource(const char* name,
+                v8::Local<v8::Object> resource = New<v8::Object>());
+  ~AsyncResource();
+
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            v8::Local<v8::Function> func,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            v8::Local<v8::String> symbol,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            const char* method,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+};
+```
+
+* `name`: Identifier for the kind of resource that is being provided for diagnostics information exposed by the [async_hooks][]
+  API. This will be passed to the possible `init` hook as the `type`. To avoid name collisions with other modules we recommend
+  that the name include the name of the owning module as a prefix. For example `mysql` module could use something like
+  `mysql:batch-db-query-resource`.
+* `resource`: An optional object associated with the async work that will be passed to the possible [async_hooks][]
+  `init` hook. If this parameter is omitted, or an empty handle is provided, this object will be created automatically.
+* When calling JS on behalf of this resource, one can use `runInAsyncScope`. This will ensure that the callback runs in the
+  correct async execution context.
+* `AsyncDestroy` is automatically called when an AsyncResource object is destroyed.
+
+For more details, see the Node [async_hooks][] documentation. You might also want to take a look at the documentation for the
+[N-API counterpart][napi]. For example usage, see the `asyncresource.cpp` example in the `test/cpp` directory.
+
+<a name="api_nan_make_callback"></a>
+### Nan::MakeCallback()
+
+Deprecated wrappers around the legacy `node::MakeCallback()` APIs. Node.js 10+
+has deprecated these legacy APIs as they do not provide a mechanism to preserve
+async context.
+
+We recommend that you use the `AsyncResource` class and `AsyncResource::runInAsyncScope` instead of using `Nan::MakeCallback` or
+`v8::Function#Call()` directly. `AsyncResource` properly takes care of running the callback in the correct async execution
+context – something that is essential for functionality like domains, async_hooks and async debugging.

+### Nan::Export()
+
+A simple helper to register a `v8::FunctionTemplate` from a JavaScript-accessible method (see [Methods](./methods.md)) as a property on an object. Can be used in a way similar to assigning properties to `module.exports` in JavaScript.

+
+See the Node documentation on [Wrapping C++ Objects](https://nodejs.org/api/addons.html#addons_wrapping_c_objects) for more details.
+
+### This vs. Holder
+
+When calling `Unwrap`, it is important that the argument is indeed some JavaScript object which got wrapped by a `Wrap` call for this class or any derived class.
+The `Signature` installed by [`Nan::SetPrototypeMethod()`](methods.md#api_nan_set_prototype_method) does ensure that `info.Holder()` is just such an instance.
+In Node 0.12 and later, `info.This()` will also be of such a type, since otherwise the invocation will get rejected.
+However, in Node 0.10 and before it was possible to invoke a method on a JavaScript object which just had the extension type in its prototype chain.
+In such a situation, calling `Unwrap` on `info.This()` will likely lead to a failed assertion causing a crash, but could lead to even more serious corruption.
+
+On the other hand, calling `Unwrap` in an [accessor](methods.md#api_nan_set_accessor) should not use `Holder()` if the accessor is defined on the prototype.
+So either define your accessors on the instance template,
+or use `This()` after verifying that it is indeed a valid object.
+
+### Examples
+
+#### Basic
+
+```c++
+class MyObject : public Nan::ObjectWrap {
+ public:
+  static NAN_MODULE_INIT(Init) {
+    v8::Local<v8::FunctionTemplate> tpl = Nan::New<v8::FunctionTemplate>(New);
+    tpl->SetClassName(Nan::New("MyObject").ToLocalChecked());
+    tpl->InstanceTemplate()->SetInternalFieldCount(1);
+
+    Nan::SetPrototypeMethod(tpl, "getHandle", GetHandle);
+    Nan::SetPrototypeMethod(tpl, "getValue", GetValue);
+
+    constructor().Reset(Nan::GetFunction(tpl).ToLocalChecked());
+    Nan::Set(target, Nan::New("MyObject").ToLocalChecked(),
+      Nan::GetFunction(tpl).ToLocalChecked());
+  }
+
+ private:
+  explicit MyObject(double value = 0) : value_(value) {}
+  ~MyObject() {}
+
+  static NAN_METHOD(New) {
+    if (info.IsConstructCall()) {
+      double value = info[0]->IsUndefined() ? 0 : Nan::To<double>(info[0]).FromJust();
+      MyObject *obj = new MyObject(value);
+      obj->Wrap(info.This());
+      info.GetReturnValue().Set(info.This());
+    } else {
+      const int argc = 1;
+      v8::Local<v8::Value> argv[argc] = {info[0]};
+      v8::Local<v8::Function> cons = Nan::New(constructor());
+      info.GetReturnValue().Set(Nan::NewInstance(cons, argc, argv).ToLocalChecked());
+    }
+  }
+
+  static NAN_METHOD(GetHandle) {
+    MyObject* obj = Nan::ObjectWrap::Unwrap<MyObject>(info.Holder());

+
+  static NAN_METHOD(GetValue) {

+
+  static inline Nan::Persistent<v8::Function> & constructor() {
+    static Nan::Persistent<v8::Function> my_constructor;
+    return my_constructor;
+  }
+
+  double value_;
+};
+
+NODE_MODULE(objectwrapper, MyObject::Init)
+```
+
+To use in Javascript:
+
+```Javascript
+var objectwrapper = require('bindings')('objectwrapper');
+
+var obj = new objectwrapper.MyObject(5);
+console.log('Should be 5: ' + obj.getValue());
+```
+

+var wrappedobjectfactory = require('bindings')('wrappedobjectfactory');
+
+var obj = wrappedobjectfactory.newFactoryObjectInstance(10);

+```
+
+#### Passing wrapped objects around
+

+
+```c++
+static NAN_METHOD(Sum) {
+  Nan::MaybeLocal<v8::Object> maybe1 = Nan::To<v8::Object>(info[0]);

+    return;
+  }
+
+  MyFactoryObject* obj1 =
+    Nan::ObjectWrap::Unwrap<MyFactoryObject>(maybe1.ToLocalChecked());
+  MyFactoryObject* obj2 =
+    Nan::ObjectWrap::Unwrap<MyFactoryObject>(maybe2.ToLocalChecked());
+
+  info.GetReturnValue().Set(Nan::New<v8::Number>(obj1->value() + obj2->value()));
+}
+
+NAN_MODULE_INIT(Init) {
+  MyFactoryObject::Init(target);
+  Nan::Set(target,
+    Nan::New<v8::String>("newFactoryObjectInstance").ToLocalChecked(),

+    Nan::New<v8::String>("sum").ToLocalChecked(),
+    Nan::GetFunction(Nan::New<v8::FunctionTemplate>(Sum)).ToLocalChecked()
+  );
+}
+
+NODE_MODULE(myaddon, Init)
+```
+
+To use in Javascript:
+
+```Javascript
+var myaddon = require('bindings')('myaddon');
+
+var obj1 = myaddon.newFactoryObjectInstance(5);
+var obj2 = myaddon.newFactoryObjectInstance(10);
+console.log('sum of object values: ' + myaddon.sum(obj1, obj2));
+```

+## Persistent references
+
+An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
+
+Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

+
+A persistent handle contains a reference to a storage cell in V8 which holds an object value and which is updated by the garbage collector whenever the object is moved. A new storage cell can be created using the constructor or `Nan::PersistentBase::Reset()`. Existing handles can be disposed using an argument-less `Nan::PersistentBase::Reset()`.

+### Nan::WeakCallbackInfo
+
+`Nan::WeakCallbackInfo` is used as an argument when setting a persistent reference as weak. You may need to free any external resources attached to the object. It is a mirror of `v8:WeakCallbackInfo` as found in newer versions of V8.
+
+Definition:
+
+```c++
+template<typename T> class WeakCallbackInfo {
+ public:
+  typedef void (*Callback)(const WeakCallbackInfo<T>& data);
+
+  v8::Isolate *GetIsolate() const;

+  T *GetParameter() const;
+
+  /**
+   * Get pointer from internal field, index can be 0 or 1.
+   */
+  void *GetInternalField(int index) const;
+};
+```
+
+Example usage:
+
+```c++
+void weakCallback(const WeakCallbackInfo<int> &data) {
+  int *parameter = data.GetParameter();
+  delete parameter;
+}
+
+Persistent<v8::Object> obj;
+int *data = new int(0);
+obj.SetWeak(data, callback, WeakCallbackType::kParameter);
+```
+
+See the V8 documentation for [`WeakCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d8/d06/classv8_1_1_weak_callback_info.html) for further information.
+
+<a name="api_nan_weak_callback_type"></a>
+### Nan::WeakCallbackType
+
+Represents the type of a weak callback.
+A weak callback of type `kParameter` makes the supplied parameter to `Nan::PersistentBase::SetWeak` available through `WeakCallbackInfo::GetParameter`.
+A weak callback of type `kInternalFields` uses up to two internal fields at indices 0 and 1 on the `Nan::PersistentBase<v8::Object>` being made weak.
+Note that only `v8::Object`s and derivatives can have internal fields.
+
+Definition:
+
+```c++
+enum class WeakCallbackType { kParameter, kInternalFields };

+## Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection).
+
+<a name="api_nan_handle_scope"></a>
+### Nan::HandleScope
+
+A simple wrapper around [`v8::HandleScope`](https://v8docs.nodesource.com/node-8.16/d3/d95/classv8_1_1_handle_scope.html).
+
+Definition:
+
+```c++
+class Nan::HandleScope {
+ public:
+  Nan::HandleScope();
+  static int NumberOfHandles();
+};
+```
+
+Allocate a new `Nan::HandleScope` whenever you are creating new V8 JavaScript objects. Note that an implicit `HandleScope` is created for you on JavaScript-accessible methods so you do not need to insert one yourself.
+
+Example:
+
+```c++
+// new object is created, it needs a new scope:
+void Pointless() {
+  Nan::HandleScope scope;
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+
+// JavaScript-accessible method already has a HandleScope
+NAN_METHOD(Pointless2) {
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+```
+
+<a name="api_nan_escapable_handle_scope"></a>
+### Nan::EscapableHandleScope
+
+Similar to [`Nan::HandleScope`](#api_nan_handle_scope) but should be used in cases where a function needs to return a V8 JavaScript type that has been created within it.
+
+Definition:
+
+```c++
+class Nan::EscapableHandleScope {
+ public:
+  Nan::EscapableHandleScope();
+  static int NumberOfHandles();
+  template<typename T> v8::Local<T> Escape(v8::Local<T> value);
+}
+```
+
+Use `Escape(value)` to return the object.
+
+Example:
+
+```c++
+v8::Local<v8::Object> EmptyObj() {
+  Nan::EscapableHandleScope scope;
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+  return scope.Escape(obj);
+}

+### Nan::Utf8String
+
+Converts an object to a UTF-8-encoded character array. If conversion to a string fails (e.g. due to an exception in the toString() method of the object) then the length() method returns 0 and the * operator returns NULL. The underlying memory used for this object is managed by the object.
+
+An implementation of [`v8::String::Utf8Value`](https://v8docs.nodesource.com/node-8.16/d4/d1b/classv8_1_1_string_1_1_utf8_value.html) that is consistent across all supported versions of V8.
+
+Definition:
+
+```c++
+class Nan::Utf8String {
+ public:
+  Nan::Utf8String(v8::Local<v8::Value> from);
+
+  int length() const;
+
+  char* operator*();
+  const char* operator*() const;
+};
+```
+
+<a name="api_nan_get_current_context"></a>
+### Nan::GetCurrentContext()

+
+Signature:

+```c++
+v8::Local<v8::Context> Nan::GetCurrentContext()
+```
+
+<a name="api_nan_set_isolate_data"></a>
+### Nan::SetIsolateData()
+
+A helper to provide a consistent API to [`v8::Isolate#SetData()`](https://v8docs.nodesource.com/node-8.16/d5/dda/classv8_1_1_isolate.html#a7acadfe7965997e9c386a05f098fbe36).
+
+Signature:
+
+```c++
+void Nan::SetIsolateData(v8::Isolate *isolate, T *data)
+```
+
+
+<a name="api_nan_get_isolate_data"></a>
+### Nan::GetIsolateData()
+
+A helper to provide a consistent API to [`v8::Isolate#GetData()`](https://v8docs.nodesource.com/node-8.16/d5/dda/classv8_1_1_isolate.html#aabd223436bc1100a787dadaa024c6257).
+
+Signature:
+
+```c++
+T *Nan::GetIsolateData(v8::Isolate *isolate)
+```
+
+<a name="api_nan_typedarray_contents"></a>
+### Nan::TypedArrayContents<T>
+
+A helper class for accessing the contents of an ArrayBufferView (aka a typedarray) from C++.  If the input array is not a valid typedarray, then the data pointer of TypedArrayContents will default to `NULL` and the length will be 0.  If the data pointer is not compatible with the alignment requirements of type, an assertion error will fail.
+
+Note that you must store a reference to the `array` object while you are accessing its contents.
+
+Definition:
+
+```c++
+template<typename T>
+class Nan::TypedArrayContents {
+ public:
+  TypedArrayContents(v8::Local<Value> array);
+
+  size_t length() const;
+
+  T* const operator*();
+  const T* const operator*() const;
+};

+# once
+
+Only call a function once.
+
+## usage
+
+```javascript
+var once = require('once')
+
+function load (file, cb) {
+  cb = once(cb)
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Or add to the Function.prototype in a responsible way:
+
+```javascript
+// only has to be done once
+require('once').proto()
+
+function load (file, cb) {
+  cb = cb.once()
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Ironically, the prototype feature makes this module twice as
+complicated as necessary.
+
+To check whether you function has been called, use `fn.called`. Once the
+function is called for the first time the return value of the original
+function is saved in `fn.value` and subsequent calls will continue to
+return this value.
+
+```javascript
+var once = require('once')
+
+function load (cb) {
+  cb = once(cb)
+  var stream = createStream()
+  stream.once('data', cb)
+  stream.once('end', function () {
+    if (!cb.called) cb(new Error('not found'))
+  })
+}
+```
+
+## `once.strict(func)`
+
+Throw an error if the function is called twice.
+
+Some functions are expected to be called only once. Using `once` for them would
+potentially hide logical errors.
+
+In the example below, the `greet` function has to call the callback only once:
+
+```javascript
+function greet (name, cb) {
+  // return is missing from the if statement
+  // when no name is passed, the callback is called twice
+  if (!name) cb('Hello anonymous')
+  cb('Hello ' + name)
+}
+
+function log (msg) {
+  console.log(msg)
+}
+
+// this will print 'Hello anonymous' but the logical error will be missed
+greet(null, once(msg))
+
+// once.strict will print 'Hello anonymous' and throw an error when the callback will be called the second time
+greet(null, once.strict(msg))
+```

+
+The module name says it all, check if a protocol requires a given port.
+
+## Installation
+
+This module is intended to be used with browserify or Node.js and is distributed
+in the public npm registry. To install it simply run the following command from
+your CLI:
+
+```j
+npm install --save requires-port
+```
+
+## Usage
+
+The module exports it self as function and requires 2 arguments:
+
+1. The port number, can be a string or number.
+2. Protocol, can be `http`, `http:` or even `https://yomoma.com`. We just split
+   it at `:` and use the first result. We currently accept the following
+   protocols:
+   - `http`
+   - `https`
+   - `ws`
+   - `wss`
+   - `ftp`
+   - `gopher`
+   - `file`
+
+It returns a boolean that indicates if protocol requires this port to be added
+to your URL.
+
+```js
+'use strict';
+
+var required = require('requires-port');
+
+console.log(required('8080', 'http')) // true
+console.log(required('80', 'http'))   // false
+```

+
+The [UNIX command](http://en.wikipedia.org/wiki/Rm_(Unix)) `rm -rf` for node.
+
+Install with `npm install rimraf`, or just drop rimraf.js somewhere.
+
+## API
+
+`rimraf(f, [opts], callback)`
+
+The first parameter will be interpreted as a globbing pattern for files. If you
+want to disable globbing you can do so with `opts.disableGlob` (defaults to
+`false`). This might be handy, for instance, if you have filenames that contain
+globbing wildcard characters.
+
+The callback will be called with an error if there is one.  Certain
+errors are handled for you:
+
+* Windows: `EBUSY` and `ENOTEMPTY` - rimraf will back off a maximum of
+  `opts.maxBusyTries` times before giving up, adding 100ms of wait
+  between each attempt.  The default `maxBusyTries` is 3.
+* `ENOENT` - If the file doesn't exist, rimraf will return
+  successfully, since your desired outcome is already the case.
+* `EMFILE` - Since `readdir` requires opening a file descriptor, it's
+  possible to hit `EMFILE` if too many file descriptors are in use.
+  In the sync case, there's nothing to be done for this.  But in the
+  async case, rimraf will gradually back off with timeouts up to
+  `opts.emfileWait` ms, which defaults to 1000.
+
+## rimraf.sync
+
+It can remove stuff synchronously, too.  But that's not so good.  Use
+the async API.  It's better.
+
+## CLI
+
+If installed with `npm install rimraf -g` it can be used as a global
+command `rimraf <path> [<path> ...]` which is useful for cross platform support.
+
+## mkdirp
+
+If you need to create a directory recursively, check out
+[mkdirp](https://github.com/substack/node-mkdirp).

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+
+## Related links
+
+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+# Safe JSON Stringify
+[![Build Status](https://travis-ci.org/debitoor/safe-json-stringify.svg?branch=master)](https://travis-ci.org/debitoor/safe-json-stringify)
+[![NPM Version](https://img.shields.io/npm/v/safe-json-stringify.svg)](https://www.npmjs.com/package/safe-json-stringify)
+
+A wrapper for `JSON.stringify` that handles circular references and prevents defined getters from throwing errors.
+
+Circular references are handled by returning `[Circular]` when a circular reference is spotted.
+
+Defined getters that throw errors are handled by returning `[Throws]`.
+
+Usage
+-----
+Install it using NPM
+
+```sh
+npm install safe-json-stringify
+```
+
+And require it into your Node project.
+
+```js
+const safeJsonStringify = require('safe-json-stringify');
+const data = {foo: 'bar'}
+
+console.log(safeJsonStringify(data));
+```
+
+All the parameters of `JSON.stringify` are accepted, try e.g. the following for a nicely formatted output:
+
+```js
+console.log(safeJsonStringify(data, null, 2));
+```
+
+An `ensureProperties` function is exposed too, which returns a safe object without the stringify step. Usage: `safeJsonStringify.ensureProperties(data);`.
+
+
+Why?
+----
+The `stringify` function on the JavaScript JSON object will take any data and return a string representation of said data. If this data contains an object literal it will attempt to return the values of any enumerable property set on this object. This can be dangerous because JavaScript supports a couple of ways to define property getters on objects.
+
+The old, non-standard, and now deprecated `Object.prototype.__defineGetter__()` will define a named property which value is the return of a given function.
+
+```js
+// Never ever do this in your code. Please.
+var obj = {};
+obj.__defineGetter__('foo', function() { return 'bar'; });
+
+JSON.stringify(obj); // {"foo":"bar"}
+```
+
+This is kinda bad because we could make that function throw an error.
+
+```js
+// Never ever do this in your code. Please.
+var obj = {};
+obj.__defineGetter__('foo', function() { throw new Error('ouch!'); });
+
+JSON.stringify(obj); // error thrown
+```
+
+This property is created as an enumerable on the object, so the object from the previous example would make any function that iterates choke and throw an error. This is bad because one would never expect a simple property get to throw an error and bring down a system.
+
+`JSON.stringify` will blindly trust any object property, and will throw an error if it hits a defined property that throws an error. This could potentially take down your program.
+
+The slightly better `Object.defineProperty()` does the same thing, but has the common courtesy to not define the getter as enumerable--that is per default. The following example would bring us in the same situation as with `__defineGetter__`.
+
+```js
+// Never ever do this in your code. Please.
+var obj = {};
+Object.defineProperty(obj, 'foo', {
+    get: function() { throw new Error('ouch!'); },
+        enumerable: true // enumerable is false by default
+});
+
+JSON.stringify(obj); // error thrown
+```
+
+So, we can not trust any of them. One could argue that they should never be used, and we can, and should, apply that principle to our own software, but we cannot trust code from third-party modules. If data from third-party modules are to be stringified by JSON we should take these situations into considerations. This module attempt to do that by spotting defined getters and return "[Throws]" if said getter throws an error.
+
+```js
+var safeJsonStringify = require('safe-json-stringify');
+// Never ever do this in your code. Please.
+var obj = {};
+Object.defineProperty(obj, 'foo', {
+    get: function() { throw new Error('ouch!'); },
+        enumerable: true
+});
+
+safeJsonStringify(obj); // '{"foo":"[Throws]"}'
+```
+
+And it attempts to handle circular references too. It returns "[Circular]" if it spots one.

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Install
+
+```bash
+npm install --save semver
+````
+
+## Usage
+
+As a node module:
+
+```js
+const semver = require('semver')
+
+semver.valid('1.2.3') // '1.2.3'
+semver.valid('a.b.c') // null
+semver.clean('  =v1.2.3   ') // '1.2.3'
+semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+semver.gt('1.2.3', '9.8.7') // false
+semver.lt('1.2.3', '9.8.7') // true
+semver.valid(semver.coerce('v2')) // '2.0.0'
+semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
+```
+
+As a command-line utility:
+
+```
+$ semver -h
+
+A JavaScript implementation of the http://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+        Print versions that match the specified range.
+
+-i --increment [<level>]
+        Increment a version by the specified level.  Level can
+        be one of: major, minor, patch, premajor, preminor,
+        prepatch, or prerelease.  Default level is 'patch'.
+        Only one version may be specified.
+
+--preid <identifier>
+        Identifier to be used to prefix premajor, preminor,
+        prepatch or prerelease version increments.
+
+-l --loose
+        Interpret versions and ranges loosely
+
+-p --include-prerelease
+        Always include prerelease versions in range matching
+
+-c --coerce
+        Coerce a string into SemVer if possible
+        (does not imply --loose)
+
+Program exits successfully if any valid version satisfies
+all supplied ranges, and prints all satisfying versions.
+
+If no satisfying versions are found, then exits failure.
+
+Versions are printed in ascending order, so supplying
+multiple versions to the utility will just sort them.
+```
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<http://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta')
+// '1.2.4-beta.0'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```bash
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any version satisfies)
+* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero digit in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0`
+* `^0.2.3` := `>=0.2.3 <0.3.0`
+* `^0.0.3` := `>=0.0.3 <0.0.4`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0`
+* `^0.0.x` := `>=0.0.0 <0.1.0`
+* `^0.0` := `>=0.0.0 <0.1.0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0`
+* `^0.x` := `>=0.0.0 <1.0.0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `options` object argument.  All
+options in this object are `false` by default.  The options supported
+are:
+
+- `loose`  Be more forgiving about not-quite-valid semver strings.
+  (Any resulting output will always be 100% strict compliant, of
+  course.)  For backwards compatibility reasons, if the `options`
+  argument is a boolean value instead of an object, it is interpreted
+  to be the `loose` param.
+- `includePrerelease`  Set to suppress the [default
+  behavior](https://github.com/npm/node-semver#prerelease-tags) of
+  excluding prerelease tagged versions from ranges unless they are
+  explicitly opted into.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
+  or comparators intersect.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+### Comparators
+
+* `intersects(comparator)`: Return true if the comparators intersect
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+* `intersects(range)`: Return true if any of the ranges comparators intersect
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.
+
+### Coercion
+
+* `coerce(version)`: Coerces a string to semver if possible
+
+This aims to provide a very forgiving translation of a non-semver
+string to semver. It looks for the first digit in a string, and
+consumes all remaining characters which satisfy at least a partial semver
+(e.g., `1`, `1.2`, `1.2.3`) up to the max permitted length (256 characters).
+Longer versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`).
+All surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes `3.4.0`).
+Only text which lacks digits will fail coercion (`version one` is not valid).
+The maximum  length for any semver component considered for coercion is 16 characters;
+longer components will be ignored (`10000000000000000.4.7.4` becomes `4.7.4`).
+The maximum value for any semver component is `Integer.MAX_SAFE_INTEGER || (2**53 - 1)`;
+higher value components are invalid (`9999999999999999.4.7.4` is likely invalid).

+## How to use
+
+This module is not intended for end-user usage, but can be used as an
+interface to inherit from from other adapters you might want to build.
+
+As an example of an adapter that builds on top of this, please take a look
+at [socket.io-redis](https://github.com/learnboost/socket.io-redis).

+
+## How to use
+
+A standalone build of `socket.io-client` is exposed automatically by the
+socket.io server as `/socket.io/socket.io.js`. Alternatively you can
+serve the file `socket.io.js` found in the `dist` folder.
+
+```html
+<script src="/socket.io/socket.io.js"></script>
+<script>
+  var socket = io('http://localhost');
+  socket.on('connect', function(){});
+  socket.on('event', function(data){});
+  socket.on('disconnect', function(){});
+</script>
+```
+
+```js
+// with ES6 import
+import io from 'socket.io-client';
+
+const socket = io('http://localhost');
+```
+
+A slim build (without `JSON3`, a JSON polyfill for IE6/IE7, and `debug`) is also available: `socket.io.slim.js`.
+
+Socket.IO is compatible with [browserify](http://browserify.org/) and [webpack](https://webpack.js.org/) (see example [there](https://github.com/socketio/socket.io/tree/2.0.3/examples/webpack-build)).
+
+### Node.JS (server-side usage)
+
+  Add `socket.io-client` to your `package.json` and then:
+
+  ```js
+  var socket = require('socket.io-client')('http://localhost');
+  socket.on('connect', function(){});
+  socket.on('event', function(data){});
+  socket.on('disconnect', function(){});
+  ```

+# socket.io-parser
+
+[![Build Status](https://secure.travis-ci.org/socketio/socket.io-parser.svg?branch=master)](http://travis-ci.org/socketio/socket.io-parser)
+[![NPM version](https://badge.fury.io/js/socket.io-parser.svg)](http://badge.fury.io/js/socket.io-parser)
+
+A socket.io encoder and decoder written in JavaScript complying with version `3`
+of [socket.io-protocol](https://github.com/socketio/socket.io-protocol).
+Used by [socket.io](https://github.com/automattic/socket.io) and
+[socket.io-client](https://github.com/automattic/socket.io-client).
+
+## Parser API
+
+  socket.io-parser is the reference implementation of socket.io-protocol. Read
+  the full API here:
+  [socket.io-protocol](https://github.com/learnboost/socket.io-protocol).
+
+## Example Usage
+
+### Encoding and decoding a packet
+
+```js
+var parser = require('socket.io-parser');
+var encoder = new parser.Encoder();
+var packet = {
+  type: parser.EVENT,
+  data: 'test-packet',
+  id: 13
+};
+encoder.encode(packet, function(encodedPackets) {
+  var decoder = new parser.Decoder();
+  decoder.on('decoded', function(decodedPacket) {
+    // decodedPacket.type == parser.EVENT
+    // decodedPacket.data == 'test-packet'
+    // decodedPacket.id == 13
+  });
+
+  for (var i = 0; i < encodedPackets.length; i++) {
+    decoder.add(encodedPackets[i]);
+  }
+});
+```
+
+### Encoding and decoding a packet with binary data
+
+```js
+var parser = require('socket.io-parser');
+var encoder = new parser.Encoder();
+var packet = {
+  type: parser.BINARY_EVENT,
+  data: {i: new Buffer(1234), j: new Blob([new ArrayBuffer(2)])}
+  id: 15
+};
+encoder.encode(packet, function(encodedPackets) {
+  var decoder = new parser.Decoder();
+  decoder.on('decoded', function(decodedPacket) {
+    // decodedPacket.type == parser.BINARY_EVENTEVENT
+    // Buffer.isBuffer(decodedPacket.data.i) == true
+    // Buffer.isBuffer(decodedPacket.data.j) == true
+    // decodedPacket.id == 15
+  });
+
+  for (var i = 0; i < encodedPackets.length; i++) {
+    decoder.add(encodedPackets[i]);
+  }
+});
+```
+See the test suite for more examples of how socket.io-parser is used.

+
+## Features
+
+Socket.IO enables real-time bidirectional event-based communication. It consists in:
+
+- a Node.js server (this repository)
+- a [Javascript client library](https://github.com/socketio/socket.io-client) for the browser (or a Node.js client)
+
+Some implementations in other languages are also available:
+
+- [Java](https://github.com/socketio/socket.io-client-java)
+- [C++](https://github.com/socketio/socket.io-client-cpp)
+- [Swift](https://github.com/socketio/socket.io-client-swift)
+- [Dart](https://github.com/rikulo/socket.io-client-dart)
+
+Its main features are:
+
+#### Reliability
+
+Connections are established even in the presence of:
+  - proxies and load balancers.
+  - personal firewall and antivirus software.
+
+For this purpose, it relies on [Engine.IO](https://github.com/socketio/engine.io), which first establishes a long-polling connection, then tries to upgrade to better transports that are "tested" on the side, like WebSocket. Please see the [Goals](https://github.com/socketio/engine.io#goals) section for more information.
+
+#### Auto-reconnection support
+
+Unless instructed otherwise a disconnected client will try to reconnect forever, until the server is available again. Please see the available reconnection options [here](https://github.com/socketio/socket.io-client/blob/master/docs/API.md#new-managerurl-options).
+
+#### Disconnection detection
+
+A heartbeat mechanism is implemented at the Engine.IO level, allowing both the server and the client to know when the other one is not responding anymore.
+
+That functionality is achieved with timers set on both the server and the client, with timeout values (the `pingInterval` and `pingTimeout` parameters) shared during the connection handshake. Those timers require any subsequent client calls to be directed to the same server, hence the `sticky-session` requirement when using multiples nodes.
+
+#### Binary support
+
+Any serializable data structures can be emitted, including:
+
+- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob) in the browser
+- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Buffer](https://nodejs.org/api/buffer.html) in Node.js
+
+#### Simple and convenient API
+
+Sample code:
+
+```js
+io.on('connection', function(socket){
+  socket.emit('request', /* */); // emit an event to the socket
+  io.emit('broadcast', /* */); // emit an event to all connected sockets
+  socket.on('reply', function(){ /* */ }); // listen to the event
+});
+```
+
+#### Cross-browser
+
+Browser support is tested in Saucelabs:
+
+[![Sauce Test Status](https://saucelabs.com/browser-matrix/socket.svg)](https://saucelabs.com/u/socket)
+
+#### Multiplexing support
+
+In order to create separation of concerns within your application (for example per module, or based on permissions), Socket.IO allows you to create several `Namespaces`, which will act as separate communication channels but will share the same underlying connection.
+
+#### Room support
+
+Within each `Namespace`, you can define arbitrary channels, called `Rooms`, that sockets can join and leave. You can then broadcast to any given room, reaching every socket that has joined it.
+
+This is a useful feature to send notifications to a group of users, or to a given user connected on several devices for example.
+
+
+**Note:** Socket.IO is not a WebSocket implementation. Although Socket.IO indeed uses WebSocket as a transport when possible, it adds some metadata to each packet: the packet type, the namespace and the ack id when a message acknowledgement is needed. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a WebSocket server (like `ws://echo.websocket.org`) either. Please see the protocol specification [here](https://github.com/socketio/socket.io-protocol).
+
+## Installation
+
+```bash
+npm install socket.io --save
+```
+
+## How to use
+
+The following example attaches socket.io to a plain Node.JS
+HTTP server listening on port `3000`.
+
+```js
+var server = require('http').createServer();
+var io = require('socket.io')(server);
+io.on('connection', function(client){
+  client.on('event', function(data){});
+  client.on('disconnect', function(){});
+});
+server.listen(3000);
+```
+
+### Standalone
+
+```js
+var io = require('socket.io')();
+io.on('connection', function(client){});
+io.listen(3000);
+```
+
+### In conjunction with Express
+
+Starting with **3.0**, express applications have become request handler
+functions that you pass to `http` or `http` `Server` instances. You need
+to pass the `Server` to `socket.io`, and not the express application
+function. Also make sure to call `.listen` on the `server`, not the `app`.
+
+```js
+var app = require('express')();
+var server = require('http').createServer(app);
+var io = require('socket.io')(server);
+io.on('connection', function(){ /* … */ });
+server.listen(3000);
+```
+
+### In conjunction with Koa
+
+Like Express.JS, Koa works by exposing an application as a request
+handler function, but only by calling the `callback` method.
+
+```js
+var app = require('koa')();
+var server = require('http').createServer(app.callback());
+var io = require('socket.io')(server);
+io.on('connection', function(){ /* … */ });
+server.listen(3000);
+```
+
+## Documentation
+
+Please see the documentation [here](/docs/README.md). Contributions are welcome!
+
+## Debug / logging
+
+Socket.IO is powered by [debug](https://github.com/visionmedia/debug).
+In order to see all the debug output, run your app with the environment variable
+`DEBUG` including the desired scope.
+
+To see the output from all of Socket.IO's debugging scopes you can use:
+
+```
+DEBUG=socket.io* node myapp
+```
+
+## Testing
+
+```
+npm test
+```
+This runs the `gulp` task `test`. By default the test will be run with the source code in `lib` directory.
+
+Set the environmental variable `TEST_VERSION` to `compat` to test the transpiled es5-compat version of the code.
+
+The `gulp` task `test` will always transpile the source code into es5 and export to `dist` first before running the test.

+v0.9.2 on 2015-05-29
+--------------------
+
+- fix a caching bug, which was a regression in 0.9.0 ([issue #63](https://github.com/samsonjs/strftime/issues/63))
+
+- update license attribute in package.json as required by npm
+  Thanks to [Peter deHaan](https://github.com/pdehaan)
+
+- construct GMT times used in tests in a more robust way
+
+- fix a bug calculating week numbers ([issue #56](https://github.com/samsonjs/strftime/issues/56))
+  Thanks to [Alexandr Nikitin](https://github.com/alexandrnikitin)
+
+- warn about possible misuse of %:: or %::: modifiers
+
+v0.9.1 on 2015-03-16
+--------------------
+
+- re-fix [issue #38](https://github.com/samsonjs/strftime/pull/38) which was lost in the v0.9 merge
+
+- add this changelog
+
+v0.9.0 on 2015-03-15
+--------------------
+
+This release marks the final run up to v1.0, which should be released by March 2016.
+
+The headline feature is a huge performance boost resulting from [this contest](http://hola.org/challenge_js). [Alexandr Nikitin](https://github.com/alexandrnikitin) has essentially [rewritten](https://github.com/samsonjs/strftime/pull/41) the code and [the results](http://jsperf.com/strftime-optimization/2) speak for themselves.
+
+Along with this the API has been unified and cleaned up. `strftimeTZ`, `strftimeUTC`, and `localizedStrftime` have all been deprecated in favour of the following functions: `timezone(tz)`, `utc()`, and `localize(locale)`. You use them like so:
+
+```JavaScript
+    var strftime = require('strftime'); // not required in web browsers
+    
+    var strftimeIT = strftime.localize(anItalianLocale);
+    var strftimePST = strftime.timezone('-0800');
+    var strftimeUTC = strftime.utc();
+    
+    // You can combine them
+    var strftimeIT_PST = strftimeIT.timezone('-0800');
+    
+    // And chain them all at once
+    var strftimeIT_PST = strftime.localize(anItalianLocale).timezone('-0800');
+```
+
+The previous API is deprecated and will be removed for v1.0. The good news is that the previous API is supported by adapting the new API, so you get most of the performance benefits before you even update your code to use the new API.
+
+The new API does not support passing in a custom timezone or locale on each call to `strftime`. This is a regression so if you really need this use case [let us know](https://github.com/samsonjs/strftime/issues/new) and we'll figure something out.
+
+Thanks to all contributors that have helped to improve this library over the past 4 years.
+

+strftime
+========
+
+strftime for JavaScript. Works in (at least) node.js and browsers. Supports localization and timezones. Most standard specifiers from C are supported as well as some other extensions from Ruby.
+
+
+Installation
+============
+
+[node](https://nodejs.org):
+
+    npm install strftime
+
+[bower](http://bower.io):
+
+    bower install strftime
+
+[component](https://github.com/componentjs/component):
+
+    component install samsonjs/strftime
+
+Or you can copy [strftime.js](https://github.com/samsonjs/strftime/blob/master/strftime.js) wherever you want to use it, whether that's with a &lt;script&gt; tag or `require` or anything else.
+
+The New API in 0.9
+==================
+
+The current version, 0.9, deprecates the older API that exported several functions: `strftimeTZ`, `strftimeUTC`, and `localizedStrftime`. In addition to this the exported function referenced itself as `require('strftime').strftime` or `window.strftime.strftime` for consistency with the other functions. *These functions are deprecated in 0.9 and will be removed in 1.0.*
+
+Now you only need the single object exported and you can create a specialized version of it using the functions `utc()`, `localize(locale)`, and `timezone(offset)`. You can no longer pass in a timezone or locale on each call to `strftime` which is a regression. If you need this let me know and we will add it back into the API.
+
+[More details are available in the changelog](https://github.com/samsonjs/strftime/blob/master/Changelog.md).
+
+Usage
+=====
+
+```JavaScript
+    var strftime = require('strftime') // not required in browsers
+    console.log(strftime('%B %d, %Y %H:%M:%S')) // => April 28, 2011 18:21:08
+    console.log(strftime('%F %T', new Date(1307472705067))) // => 2011-06-07 18:51:45
+```
+
+
+If you want to localize it:
+
+```JavaScript
+    var strftime = require('strftime') // not required in browsers
+    var it_IT = {
+        days: ['domenica', 'lunedi', 'martedi', 'mercoledi', 'giovedi', 'venerdi', 'sabato'],
+        shortDays: ['dom', 'lun', 'mar', 'mer', 'gio', 'ven', 'sab'],
+        months: ['gennaio', 'febbraio', 'marzo', 'aprile', 'maggio', 'giugno', 'luglio', 'agosto', 'settembre', 'ottobre', 'novembre', 'dicembre'],
+        shortMonths: ['gen', 'feb', 'mar', 'apr', 'mag', 'giu', 'lug', 'ago', 'set', 'ott', 'nov', 'dic'],
+        AM: 'AM',
+        PM: 'PM',
+        am: 'am',
+        pm: 'pm',
+        formats: {
+            D: '%m/%d/%y',
+            F: '%Y-%m-%d',
+            R: '%H:%M',
+            X: '%T',
+            c: '%a %b %d %X %Y',
+            r: '%I:%M:%S %p',
+            T: '%H:%M:%S',
+            v: '%e-%b-%Y',
+            x: '%D'
+        }
+    }
+    var strftimeIT = strftime.localize(it_IT)
+    console.log(strftimeIT('%B %d, %Y %H:%M:%S')) // => aprile 28, 2011 18:21:08
+    console.log(strftimeIT('%B %d, %Y %H:%M:%S', new Date(1307472705067))) // => giugno 7, 2011 18:51:45
+```
+
+Time zones can be passed in as an offset from GMT in minutes.
+
+```JavaScript
+    var strftime = require('strftime') // not required in browsers
+    var strftimePDT = strftime.timezone(-420)
+    var strftimeCEST = strftime.timezone(120)
+    console.log(strftimePDT('%B %d, %y %H:%M:%S', new Date(1307472705067))) // => June 07, 11 11:51:45
+    console.log(strftimeCEST('%F %T', new Date(1307472705067))) // => 2011-06-07 20:51:45
+```
+
+Alternatively you can use the timezone format used by ISO 8601, `+HHMM` or `-HHMM`.
+
+```JavaScript
+    var strftime = require('strftime') // not required in browsers
+    var strftimePDT = strftime.timezone('-0700')
+    var strftimeCEST = strftime.timezone('+0200')
+    console.log(strftimePDT('', new Date(1307472705067))) // => June 07, 11 11:51:45
+    console.log(strftimeCEST('%F %T', new Date(1307472705067))) // => 2011-06-07 20:51:45
+```
+
+Supported Specifiers
+====================
+
+Extensions from Ruby are noted in the following list.
+
+Unsupported specifiers are rendered without the percent sign.
+e.g. `%q` becomes `q`. Use `%%` to get a literal `%` sign.
+
+- A: full weekday name
+- a: abbreviated weekday name
+- B: full month name
+- b: abbreviated month name
+- C: AD century (year / 100), padded to 2 digits
+- c: equivalent to `%a %b %d %X %Y` in en-US (based on locale)
+- D: equivalent to `%m/%d/%y` in en-US (based on locale)
+- d: day of the month, padded to 2 digits (01-31)
+- e: day of the month, padded with a leading space for single digit values (1-31)
+- F: equivalent to `%Y-%m-%d` in en-US (based on locale)
+- H: the hour (24-hour clock), padded to 2 digits (00-23)
+- h: the same as %b (abbreviated month name)
+- I: the hour (12-hour clock), padded to 2 digits (01-12)
+- j: day of the year, padded to 3 digits (001-366)
+- k: the hour (24-hour clock), padded with a leading space for single digit values (0-23)
+- L: the milliseconds, padded to 3 digits [Ruby extension]
+- l: the hour (12-hour clock), padded with a leading space for single digit values (1-12)
+- M: the minute, padded to 2 digits (00-59)
+- m: the month, padded to 2 digits (01-12)
+- n: newline character
+- o: day of the month as an ordinal (without padding), e.g. 1st, 2nd, 3rd, 4th, ...
+- P: "am" or "pm" in lowercase (Ruby extension, based on locale)
+- p: "AM" or "PM" (based on locale)
+- R: equivalent to `%H:%M` in en-US (based on locale)
+- r: equivalent to `%I:%M:%S %p` in en-US (based on locale)
+- S: the second, padded to 2 digits (00-60)
+- s: the number of seconds since the Epoch, UTC
+- T: equivalent to `%H:%M:%S` in en-US (based on locale)
+- t: tab character
+- U: week number of the year, Sunday as the first day of the week, padded to 2 digits (00-53)
+- u: the weekday, Monday as the first day of the week (1-7)
+- v: equivalent to `%e-%b-%Y` in en-US (based on locale)
+- W: week number of the year, Monday as the first day of the week, padded to 2 digits (00-53)
+- w: the weekday, Sunday as the first day of the week (0-6)
+- X: equivalent to `%D` in en-US (based on locale)
+- x: equivalent to `%T` in en-US (based on locale)
+- Y: the year with the century
+- y: the year without the century (00-99)
+- Z: the time zone name, replaced with an empty string if it is not found
+- z: the time zone offset from UTC, with a leading plus sign for UTC and zones east
+     of UTC and a minus sign for those west of UTC, hours and minutes follow each
+     padded to 2 digits and with no delimiter between them
+
+For more detail see `man 3 strftime` as the format specifiers should behave identically. If behaviour differs please [file a bug](https://github.com/samsonjs/strftime/issues/new).
+
+Any specifier can be modified with `-`, `_`, `0`, or `:` as well, as in Ruby. Using `%-` will omit any leading zeroes or spaces, `%_` will force spaces for padding instead of the default, and `%0` will force zeroes for padding. There's some redundancy here as `%-d` and `%e` have the same result, but it solves some awkwardness with formats like `%l`. Using `%:` for time zone offset, as in `%:z` will insert a colon as a delimiter.

+
+Ultron is a high-intelligence robot. It gathers intelligence so it can start
+improving upon his rudimentary design. It will learn your event emitting
+patterns and find ways to exterminate them. Allowing you to remove only the
+event emitters that **you** assigned and not the ones that your users or
+developers assigned. This can prevent race conditions, memory leaks and even file
+descriptor leaks from ever happening as you won't remove clean up processes.
+
+## Installation
+
+The module is designed to be used in browsers using browserify and in Node.js.
+You can install the module through the public npm registry by running the
+following command in CLI:
+
+```
+npm install --save ultron
+```
+
+## Usage
+
+In all examples we assume that you've required the library as following:
+
+```js
+'use strict';
+
+var Ultron = require('ultron');
+```
+
+Now that we've required the library we can construct our first `Ultron` instance.
+The constructor requires one argument which should be the `EventEmitter`
+instance that we need to operate upon. This can be the `EventEmitter` module
+that ships with Node.js or `EventEmitter3` or anything else as long as it
+follow the same API and internal structure as these 2. So with that in mind we
+can create the instance:
+
+```js
+//
+// For the sake of this example we're going to construct an empty EventEmitter
+//
+var EventEmitter = require('events').EventEmitter; // or require('eventmitter3');
+var events = new EventEmitter();
+
+var ultron = new Ultron(events);
+```
+
+You can now use the following API's from the Ultron instance:
+
+### Ultron.on
+
+Register a new event listener for the given event. It follows the exact same API
+as `EventEmitter.on` but it will return itself instead of returning the
+EventEmitter instance. If you are using EventEmitter3 it also supports the
+context param:
+
+```js
+ultron.on('event-name', handler, { custom: 'function context' });
+```
+
+Just like you would expect, it can also be chained together.
+
+```js
+ultron
+.on('event-name', handler)
+.on('another event', handler);
+```
+
+### Ultron.once
+
+Exactly the same as the [Ultron.on](#ultronon) but it only allows the execution
+once.
+
+Just like you would expect, it can also be chained together.
+
+```js
+ultron
+.once('event-name', handler, { custom: 'this value' })
+.once('another event', handler);
+```
+
+### Ultron.remove
+
+This is where all the magic happens and the safe removal starts. This function
+accepts different argument styles:
+
+- No arguments, assume that all events need to be removed so it will work as
+  `removeAllListeners()` API.
+- 1 argument, when it's a string it will be split on ` ` and `,` to create a
+  list of events that need to be cleared.
+- Multiple arguments, we assume that they are all names of events that need to
+  be cleared.
+
+```js
+ultron.remove('foo, bar baz');        // Removes foo, bar and baz.
+ultron.remove('foo', 'bar', 'baz');   // Removes foo, bar and baz.
+ultron.remove();                      // Removes everything.
+```
+
+If you just want to remove a single event listener using a function reference
+you can still use the EventEmitter's `removeListener(event, fn)` API:
+
+```js
+function foo() {}
+
+ultron.on('foo', foo);
+events.removeListener('foo', foo);
+```

+# ws: a node.js websocket library
+
+[![Build Status](https://travis-ci.org/websockets/ws.svg?branch=master)](https://travis-ci.org/websockets/ws)
+
+`ws` is a simple to use WebSocket implementation, up-to-date against RFC-6455,
+and [probably the fastest WebSocket library for node.js][archive].
+
+Passes the quite extensive Autobahn test suite. See http://websockets.github.com/ws
+for the full reports.
+
+## Protocol support
+
+* **Hixie draft 76** (Old and deprecated, but still in use by Safari and Opera.
+  Added to ws version 0.4.2, but server only. Can be disabled by setting the
+  `disableHixie` option to true.)
+* **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
+* **HyBi drafts 13-17** (Current default, alternatively option `protocolVersion: 13`)
+
+### Installing
+
+```
+npm install --save ws
+```
+
+### Opt-in for performance
+
+There are 2 optional modules that can be installed along side with the `ws`
+module. These modules are binary addons which improve certain operations, but as
+they are binary addons they require compilation which can fail if no c++
+compiler is installed on the host system.
+
+- `npm install --save bufferutil`: Improves internal buffer operations which
+  allows for faster processing of masked WebSocket frames and general buffer
+  operations.
+- `npm install --save utf-8-validate`: The specification requires validation of
+  invalid UTF-8 chars, some of these validations could not be done in JavaScript
+  hence the need for a binary addon. In most cases you will already be
+  validating the input that you receive for security purposes leading to double
+  validation. But if you want to be 100% spec-conforming and have fast
+  validation of UTF-8 then this module is a must.
+
+### Sending and receiving text data
+
+```js
+var WebSocket = require('ws');
+var ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+  ws.send('something');
+});
+
+ws.on('message', function(data, flags) {
+  // flags.binary will be set if a binary data is received.
+  // flags.masked will be set if the data was masked.
+});
+```
+
+### Sending binary data
+
+```js
+var WebSocket = require('ws');
+var ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+  var array = new Float32Array(5);
+
+  for (var i = 0; i < array.length; ++i) {
+    array[i] = i / 2;
+  }
+
+  ws.send(array, { binary: true, mask: true });
+});
+```
+
+Setting `mask`, as done for the send options above, will cause the data to be
+masked according to the WebSocket protocol. The same option applies for text
+data.
+
+### Server example
+
+```js
+var WebSocketServer = require('ws').Server
+  , wss = new WebSocketServer({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(message) {
+    console.log('received: %s', message);
+  });
+
+  ws.send('something');
+});
+```
+
+### ExpressJS example
+
+```js
+var server = require('http').createServer()
+  , url = require('url')
+  , WebSocketServer = require('ws').Server
+  , wss = new WebSocketServer({ server: server })
+  , express = require('express')
+  , app = express()
+  , port = 4080;
+
+app.use(function (req, res) {
+  res.send({ msg: "hello" });
+});
+
+wss.on('connection', function connection(ws) {
+  var location = url.parse(ws.upgradeReq.url, true);
+  // you might use location.query.access_token to authenticate or share sessions
+  // or ws.upgradeReq.headers.cookie (see http://stackoverflow.com/a/16395220/151312)
+
+  ws.on('message', function incoming(message) {
+    console.log('received: %s', message);
+  });
+
+  ws.send('something');
+});
+
+server.on('request', app);
+server.listen(port, function () { console.log('Listening on ' + server.address().port) });
+```
+
+### Server sending broadcast data
+
+```js
+var WebSocketServer = require('ws').Server
+  , wss = new WebSocketServer({ port: 8080 });
+
+wss.broadcast = function broadcast(data) {
+  wss.clients.forEach(function each(client) {
+    client.send(data);
+  });
+};
+```
+
+### Error handling best practices
+
+```js
+// If the WebSocket is closed before the following send is attempted
+ws.send('something');
+
+// Errors (both immediate and async write errors) can be detected in an optional
+// callback. The callback is also the only way of being notified that data has
+// actually been sent.
+ws.send('something', function ack(error) {
+  // if error is not defined, the send has been completed,
+  // otherwise the error object will indicate what failed.
+});
+
+// Immediate errors can also be handled with try/catch-blocks, but **note** that
+// since sends are inherently asynchronous, socket write failures will *not* be
+// captured when this technique is used.
+try { ws.send('something'); }
+catch (e) { /* handle error */ }
+```
+
+### echo.websocket.org demo
+
+```js
+var WebSocket = require('ws');
+var ws = new WebSocket('ws://echo.websocket.org/', {
+  protocolVersion: 8,
+  origin: 'http://websocket.org'
+});
+
+ws.on('open', function open() {
+  console.log('connected');
+  ws.send(Date.now().toString(), {mask: true});
+});
+
+ws.on('close', function close() {
+  console.log('disconnected');
+});
+
+ws.on('message', function message(data, flags) {
+  console.log('Roundtrip time: ' + (Date.now() - parseInt(data)) + 'ms', flags);
+
+  setTimeout(function timeout() {
+    ws.send(Date.now().toString(), {mask: true});
+  }, 500);
+});
+```
+
+### Other examples
+
+For a full example with a browser client communicating with a ws server, see the
+examples folder.
+
+Note that the usage together with Express 3.0 is quite different from Express
+2.x. The difference is expressed in the two different serverstats-examples.
+
+Otherwise, see the test cases.
+
+### Running the tests
+
+```
+make test
+```

+
+Ultron is a high-intelligence robot. It gathers intelligence so it can start
+improving upon his rudimentary design. It will learn your event emitting
+patterns and find ways to exterminate them. Allowing you to remove only the
+event emitters that **you** assigned and not the ones that your users or
+developers assigned. This can prevent race conditions, memory leaks and even file
+descriptor leaks from ever happening as you won't remove clean up processes.
+
+## Installation
+
+The module is designed to be used in browsers using browserify and in Node.js.
+You can install the module through the public npm registry by running the
+following command in CLI:
+
+```
+npm install --save ultron
+```
+
+## Usage
+
+In all examples we assume that you've required the library as following:
+
+```js
+'use strict';
+
+var Ultron = require('ultron');
+```
+
+Now that we've required the library we can construct our first `Ultron` instance.
+The constructor requires one argument which should be the `EventEmitter`
+instance that we need to operate upon. This can be the `EventEmitter` module
+that ships with Node.js or `EventEmitter3` or anything else as long as it
+follow the same API and internal structure as these 2. So with that in mind we
+can create the instance:
+
+```js
+//
+// For the sake of this example we're going to construct an empty EventEmitter
+//
+var EventEmitter = require('events').EventEmitter; // or require('eventmitter3');
+var events = new EventEmitter();
+
+var ultron = new Ultron(events);
+```
+
+You can now use the following API's from the Ultron instance:
+
+### Ultron.on
+
+Register a new event listener for the given event. It follows the exact same API
+as `EventEmitter.on` but it will return itself instead of returning the
+EventEmitter instance. If you are using EventEmitter3 it also supports the
+context param:
+
+```js
+ultron.on('event-name', handler, { custom: 'function context' });
+```
+
+### Ultron.once
+
+Exactly the same as the [Ultron.on](#ultronon) but it only allows the execution
+once.
+
+### Ultron.remove
+
+This is where all the magic happens and the safe removal starts. This function
+accepts different argument styles:
+
+- No arguments, assume that all events need to be removed so it will work as
+  `removeAllListeners()` API.
+- 1 argument, when it's a string it will be split on ` ` and `,` to create a
+  list of events that need to be cleared.
+- Multiple arguments, we assume that they are all names of events that need to
+  be cleared.
+
+```js
+ultron.remove('foo, bar baz');        // Removes foo, bar and baz.
+ultron.remove('foo', 'bar', 'baz');   // Removes foo, bar and baz.
+ultron.remove();                      // Removes everything.
+```
+
+If you just want to remove a single event listener using a function reference
+you can still use the EventEmitter's `removeListener(event, fn)` API:
+
+```js
+function foo() {}
+
+ulton.on('foo', foo);
+events.removeListener('foo', foo);
+```

+# node-XMLHttpRequest #
+
+Fork of [node-XMLHttpRequest](https://github.com/driverdan/node-XMLHttpRequest) by [driverdan](http://driverdan.com). Forked and published to npm because a [pull request](https://github.com/rase-/node-XMLHttpRequest/commit/a6b6f296e0a8278165c2d0270d9840b54d5eeadd) is not being created and merged. Changes made by [rase-](https://github.com/rase-/node-XMLHttpRequest/tree/add/ssl-support) are needed for [engine.io-client](https://github.com/Automattic/engine.io-client).
+
+## Usage ## 
+
+Here's how to include the module in your project and use as the browser-based
+XHR object.
+
+	var XMLHttpRequest = require("xmlhttprequest-ssl").XMLHttpRequest;
+	var xhr = new XMLHttpRequest();
+
+Note: use the lowercase string "xmlhttprequest-ssl" in your require(). On
+case-sensitive systems (eg Linux) using uppercase letters won't work.

+## Usage ##
+
+Here's how to include the module in your project and use as the browser-based
+XHR object.
+
+	var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
+	var xhr = new XMLHttpRequest();
+
+Note: use the lowercase string "xmlhttprequest" in your require(). On
+case-sensitive systems (eg Linux) using uppercase letters won't work.
+
+## Versions ##
+
+Prior to 1.4.0 version numbers were arbitrary. From 1.4.0 on they conform to
+the standard major.minor.bugfix. 1.x shouldn't necessarily be considered
+stable just because it's above 0.x.
+
+Since the XMLHttpRequest API is stable this library's API is stable as
+well. Major version numbers indicate significant core code changes.
+Minor versions indicate minor core code changes or better conformity to
+the W3C spec.
+
+## License ##
+
+MIT license. See LICENSE for full details.
+
+## Supports ##
+
+* Async and synchronous requests
+* GET, POST, PUT, and DELETE requests
+* All spec methods (open, send, abort, getRequestHeader,
+  getAllRequestHeaders, event methods)
+* Requests to all domains
+
+## Known Issues / Missing Features ##
+
+For a list of open issues or to report your own visit the [github issues
+page](https://github.com/driverdan/node-XMLHttpRequest/issues).
+
+* Local file access may have unexpected results for non-UTF8 files
+* Synchronous requests don't set headers properly
+* Synchronous requests freeze node while waiting for response (But that's what you want, right? Stick with async!).
+* Some events are missing, such as abort
+* getRequestHeader is case-sensitive
+* Cookies aren't persisted between requests
+* Missing XML support
+* Missing basic auth

+[![Sauce Test Status](https://saucelabs.com/browser-matrix/yeast.svg)](https://saucelabs.com/u/yeast)
+
+Yeast is a unique id generator. It has been primarily designed to generate a
+unique id which can be used for cache busting. A common practice for this is
+to use a timestamp, but there are couple of downsides when using timestamps.
+
+1. The timestamp is already 13 chars long. This might not matter for 1 request
+   but if you make hundreds of them this quickly adds up in bandwidth and
+   processing time.
+2. It's not unique enough. If you generate two stamps right after each other,
+   they would be identical because the timing accuracy is limited to
+   milliseconds.
+
+Yeast solves both of these issues by:
+
+1. Compressing the generated timestamp using a custom `encode()` function that
+   returns a string representation of the number.
+2. Seeding the id in case of collision (when the id is identical to the previous
+   one).
+
+To keep the strings unique it will use the `.` char to separate the generated
+stamp from the seed.
+
+## Installation
+
+The module is intended to be used in browsers as well as in Node.js and is
+therefore released in the npm registry and can be installed using:
+
+```
+npm install --save yeast
+```
+
+## Usage
+
+All the examples assume that this library is initialized as follow:
+
+```js
+'use strict';
+
+var yeast = require('yeast');
+```
+
+To generate an id just call the `yeast` function.
+
+```js
+console.log(yeast(), yeast(), yeast()); // outputs: KyxidwN KyxidwN.0 KyxidwN.1
+
+setTimeout(function () {
+  console.log(yeast()); // outputs: KyxidwO
+});
+```
+
+### yeast.encode(num)
+
+An helper function that returns a string representing the specified number. The
+returned string contains only URL safe characters.
+
+```js
+yeast.encode(+new Date()); // outputs: Kyxjuo1
+```
+
+### yeast.decode(str)
+
+An helper function that returns the integer value specified by the given string.
+This function can be used to retrieve the timestamp from a `yeast` id.
+
+```js
+var id = yeast(); // holds the value: Kyxl1OU
+
+yeast.decode(id); // outputs: 1439816226334
+```
+
+That's all folks. If you have ideas on how we can further compress the ids
+please open an issue!

+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+    """`Any` contains an arbitrary serialized protocol buffer message along with a
+    URL that describes the type of the serialized message.
+
+    Protobuf library provides support to pack/unpack Any values in the form
+    of utility functions or additional generated methods of the Any type.
+
+    Example 1: Pack and unpack a message in C++.
+
+        Foo foo = ...;
+        Any any;
+        any.PackFrom(foo);
+        ...
+        if (any.UnpackTo(&foo)) {
+          ...
+        }
+
+    Example 2: Pack and unpack a message in Java.
+
+        Foo foo = ...;
+        Any any = Any.pack(foo);
+        ...
+        if (any.is(Foo.class)) {
+          foo = any.unpack(Foo.class);
+        }
+
+     Example 3: Pack and unpack a message in Python.
+
+        foo = Foo(...)
+        any = Any()
+        any.Pack(foo)
+        ...
+        if any.Is(Foo.DESCRIPTOR):
+          any.Unpack(foo)
+          ...
+
+     Example 4: Pack and unpack a message in Go
+
+         foo := &pb.Foo{...}
+         any, err := anypb.New(foo)
+         if err != nil {
+           ...
+         }
+         ...
+         foo := &pb.Foo{}
+         if err := any.UnmarshalTo(foo); err != nil {
+           ...
+         }
+
+    The pack methods provided by protobuf library will by default use
+    'type.googleapis.com/full.type.name' as the type URL and the unpack
+    methods only use the fully qualified type name after the last '/'
+    in the type URL, for example "foo.bar.com/x/y.z" will yield type
+    name "y.z".
+
+
+    JSON
+    ====
+    The JSON representation of an `Any` value uses the regular
+    representation of the deserialized, embedded message, with an
+    additional field `@type` which contains the type URL. Example:
+
+        package google.profile;
+        message Person {
+          string first_name = 1;
+          string last_name = 2;
+        }
+
+        {
+          "@type": "type.googleapis.com/google.profile.Person",
+          "firstName": <string>,
+          "lastName": <string>
+        }
+
+    If the embedded message type is well-known and has a custom JSON
+    representation, that representation will be embedded adding a field
+    `value` which holds the custom JSON in addition to the `@type`
+    field. Example (for message [google.protobuf.Duration][]):
+
+        {
+          "@type": "type.googleapis.com/google.protobuf.Duration",
+          "value": "1.212s"
+        }
+    """

+    VALUE_FIELD_NUMBER: builtins.int
+    type_url: typing.Text

+    protocol buffer message. This string must contain at least

+    the fully qualified name of the type (as in
+    `path/google.protobuf.Duration`). The name should be in a canonical form
+    (e.g., leading "." is not accepted).
+
+    In practice, teams usually precompile into the binary all types that they
+    expect it to use in the context of Any. However, for URLs which use the
+    scheme `http`, `https`, or no scheme, one can optionally set up a type
+    server that maps type URLs to message definitions as follows:
+
+    * If no scheme is provided, `https` is assumed.
+    * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+      value in binary format, or produce an error.
+    * Applications are allowed to cache lookup results based on the
+      URL, or have them precompiled into a binary to avoid any
+      lookup. Therefore, binary compatibility needs to be preserved
+      on changes to types. (Use versioned type names to manage
+      breaking changes.)
+
+    Note: this functionality is not currently available in the official
+    protobuf release, and it is not used for type URLs beginning with
+    type.googleapis.com.
+
+    Schemes other than `http`, `https` (or the empty scheme) might be

+      version of the including interface plus the [root][] path if
+      specified.
+

+          // Get the underlying ACL object.

+            option (google.api.http).get = "/v2/{resource=**}";
+          }
+        }
+
+    Example of a mixin configuration:

+        - name: google.storage.v2.Storage
+          mixins:
+          - name: google.acl.v1.AccessControl
+
+    The mixin construct implies that all methods in `AccessControl` are
+    also declared with same name and request/response types in
+    `Storage`. A documentation generator or annotation processor will
+    see the effective `Storage.GetAcl` method after inheriting
+    documentation and annotations as follows:
+
+        service Storage {
+          // Get the underlying ACL object.
+          rpc GetAcl(GetAclRequest) returns (Acl) {
+            option (google.api.http).get = "/v2/{resource=**}:getAcl";
+          }
+          ...
+        }
+
+    Note how the version in the path pattern changed from `v1` to `v2`.
+
+    If the `root` field in the mixin is specified, it should be a
+    relative path under which inherited HTTP paths are placed. Example:
+
+        apis:
+        - name: google.storage.v2.Storage
+          mixins:
+          - name: google.acl.v1.AccessControl
+            root: acls
+
+    This implies the following inherited HTTP annotation:
+
+        service Storage {
+          // Get the underlying ACL object.
+          rpc GetAcl(GetAclRequest) returns (Acl) {

+        content here is to be inserted into that file at a defined insertion
+        point.  This feature allows a code generator to extend the output
+        produced by another code generator.  The original generator may provide
+        insertion points by placing special annotations in the file that look
+        like:
+          @@protoc_insertion_point(NAME)
+        The annotation can have arbitrary text before and after it on the line,
+        which allows it to be placed in a comment.  NAME should be replaced with
+        an identifier naming the point -- this is what other generators will use
+        as the insertion_point.  Code inserted at this point will be placed
+        immediately above the line containing the insertion point (thus multiple
+        insertions to the same point will come out in the order they were added).
+        The double-@ is intended to make it unlikely that the generated code
+        could contain things that look like insertion points by accident.
+
+        For example, the C++ code generator places the following line in the
+        .pb.h files that it generates:
+          // @@protoc_insertion_point(namespace_scope)
+        This line appears within the scope of the file's package namespace, but
+        outside of any particular class.  Another plugin can then specify the
+        insertion_point "namespace_scope" to generate additional classes or
+        other declarations that should be placed in this scope.
+
+        Note that if the line containing the insertion point begins with
+        whitespace, the same whitespace will be added to every line of the
+        inserted text.  This is useful for languages like Python, where
+        indentation matters.  In these languages, the insertion point comment
+        should be indented the same amount as any inserted code will need to be
+        in order to work correctly in that context.
+
+        The code generator that generates the initial file and the one which
+        inserts into it must both run as part of a single invocation of protoc.
+        Code generators are executed in the order in which they appear on the
+        command line.
+
+        If |insertion_point| is present, |name| must also be present.

+
+    Each of the definitions above may have "options" attached.  These are
+    just annotations which may cause code to be generated slightly differently
+    or may contain hints for code that manipulates protocol messages.
+
+    Clients may define custom options as extensions of the *Options messages.
+    These extensions may not yet be known at parsing time, so the parser cannot
+    store the values in them.  Instead it stores them in a field in the *Options
+    message called uninterpreted_option. This field must have the same name
+    across all *Options messages. We then use this field to populate the
+    extensions when we build a descriptor, at which point all protos have been
+    parsed and so all extensions are known.
+
+    Extension numbers for custom options may be chosen as follows:
+    * For options which will only be used within a single application or
+      organization, or for experimental options, use field numbers 50000
+      through 99999.  It is up to you to ensure that you do not use the
+      same number for multiple options.
+    * For options which will be published and used publicly by multiple
+      independent entities, e-mail protobuf-global-extension-registry@google.com
+      to reserve extension numbers. Simply provide your project name (e.g.
+      Objective-C plugin) and your project website (if available) -- there's no
+      need to explain how you intend to use them. Usually you only need one
+      extension number. You can declare multiple options with only one extension
+      number by putting them in a sub-message. See the Custom Options section of
+      the docs for examples:
+      https://developers.google.com/protocol-buffers/docs/proto#options
+      If this turns out to be popular, a web service will be set up

+    This option does not affect the public interface of any generated code;
+    all method signatures remain the same.  Furthermore, thread-safety of the
+    interface is not affected by this option; const methods remain safe to
+    call from multiple threads concurrently, while non-const methods continue
+    to require exclusive access.
+
+
+    Note that implementations may choose not to check required fields within
+    a lazy sub-message.  That is, calling IsInitialized() on the outer message
+    may return true even if the inner message has missing required fields.
+    This is necessary because otherwise the inner message would have to be
+    parsed in order to perform the check, defeating the purpose of lazy
+    parsing.  An implementation which chooses not to check required fields
+    must be consistent about it.  That is, for any particular sub-message, the

+        corresponds to a particular definition.  This information is intended
+        to be useful to IDEs, code indexers, documentation generators, and similar
+        tools.
+
+        For example, say we have a file like:
+          message Foo {
+            optional string foo = 1;
+          }
+        Let's look at just the field definition:
+          optional string foo = 1;
+          ^       ^^     ^^  ^  ^^^
+          a       bc     de  f  ghi
+        We have the following locations:
+          span   path               represents
+          [a,i)  [ 4, 0, 2, 0 ]     The whole field definition.
+          [a,b)  [ 4, 0, 2, 0, 4 ]  The label (optional).
+          [c,d)  [ 4, 0, 2, 0, 5 ]  The type (string).
+          [e,f)  [ 4, 0, 2, 0, 1 ]  The name (foo).
+          [g,h)  [ 4, 0, 2, 0, 3 ]  The number (1).
+
+        Notes:
+        - A location may refer to a repeated field itself (i.e. not to any
+          particular index within it).  This is used whenever a set of elements are
+          logically enclosed in a single code segment.  For example, an entire
+          extend block (possibly containing multiple extension definitions) will
+          have an outer location whose path refers to the "extensions" repeated
+          field without an index.
+        - Multiple locations may have the same path.  This happens when a single
+          logical declaration is spread out across multiple places.  The most
+          obvious example is the "extend" block again -- there may be multiple
+          extend blocks in the same scope, each of which will have the same path.
+        - A location's span is not always a subset of its parent's span.  For
+          example, the "extendee" of an extension declaration appears at the
+          beginning of the "extend" block and is shared by all extensions within
+          the block.
+        - Just because a location's span is a subset of some other location's span
+          does not mean that it is a descendant.  For example, a "group" defines
+          both a type and a field in a single declaration.  Thus, the locations
+          corresponding to the type and field and their components will overlap.
+        - Code which tries to interpret locations should probably be designed to
+          ignore those that it doesn't understand, as more types of locations could
+          be recorded in the future.

+
+    Here `f` represents a field in some root message, `a` and `b`
+    fields in the message found in `f`, and `d` a field found in the
+    message in `f.b`.
+
+    Field masks are used to specify a subset of fields that should be
+    returned by a get operation or modified by an update operation.
+    Field masks also have a custom JSON encoding (see below).
+
+    # Field Masks in Projections
+
+    When used in the context of a projection, a response message or
+    sub-message is filtered by the API to only contain those fields as
+    specified in the mask. For example, if the mask in the previous
+    example is applied to a response message as follows:
+
+        f {
+          a : 22
+          b {
+            d : 1

+          }
+          y : 13
+        }
+        z: 8
+
+    The result will not contain specific values for fields x,y and z
+    (their value will be set to the default, and omitted in proto text
+    output):
+
+
+        f {
+          a : 22
+          b {
+            d : 1
+          }
+        }
+
+    A repeated field is not allowed except at the last position of a
+    paths string.
+
+    If a FieldMask object is not present in a get operation, the
+    operation applies to all fields (as if a FieldMask of all fields
+    had been specified).
+
+    Note that a field mask does not necessarily apply to the
+    top-level response message. In case of a REST get operation, the
+    field mask applies directly to the response, but in case of a REST
+    list operation, the mask instead applies to each individual message
+    in the returned resource list. In case of a REST custom method,
+    other definitions may be used. Where the mask applies will be
+    clearly documented together with its declaration in the API.  In
+    any case, the effect on the returned resource/resources is required
+    behavior for APIs.
+
+    # Field Masks in Update Operations
+
+    A field mask in update operations specifies which fields of the
+    targeted resource are going to be updated. The API is required
+    to only change the values of the fields as specified in the mask
+    and leave the others untouched. If a resource is passed in to
+    describe the updated values, the API ignores the values of all
+    fields not covered by the mask.
+
+    If a repeated field is specified for an update operation, new values will
+    be appended to the existing repeated field in the target resource. Note that
+    a repeated field is only allowed in the last position of a `paths` string.
+
+    If a sub-message is specified in the last position of the field mask for an
+    update operation, then new value will be merged into the existing sub-message
+    in the target resource.
+
+    For example, given the target message:
+
+        f {
+          b {
+            d: 1
+            x: 2
+          }
+          c: [1]
+        }
+
+    And an update message:
+
+        f {
+          b {
+            d: 10
+          }
+          c: [2]
+        }
+
+    then if the field mask is:
+
+     paths: ["f.b", "f.c"]
+
+    then the result will be:
+
+        f {
+          b {
+            d: 10
+            x: 2
+          }
+          c: [1, 2]
+        }
+
+    An implementation may provide options to override this default behavior for
+    repeated and message fields.
+
+    In order to reset a field's value to the default, the field must
+    be in the mask and set to the default value in the provided resource.
+    Hence, in order to reset all fields of a resource, provide a default
+    instance of the resource and set all fields in the mask, or do
+    not provide a mask as described below.
+
+    If a field mask is not present on update, the operation applies to
+    all fields (as if a field mask of all fields has been specified).
+    Note that in the presence of schema evolution, this may mean that
+    fields the client does not know and has therefore not filled into
+    the request will be reset to their default. If this is unwanted
+    behavior, a specific service may require a client to always specify
+    a field mask, producing an error if not.
+
+    As with get operations, the location of the resource which
+    describes the updated values in the request message depends on the
+    operation kind. In any case, the effect of the field mask is
+    required to be honored by the API.
+
+    ## Considerations for HTTP REST
+
+    The HTTP kind of an update operation which uses a field mask must
+    be set to PATCH instead of PUT in order to satisfy HTTP semantics
+    (PUT must only be used for full updates).
+
+    # JSON Encoding of Field Masks
+
+    In JSON, a field mask is encoded as a single string where paths are
+    separated by a comma. Fields name in each path are converted
+    to/from lower-camel naming conventions.
+
+    As an example, consider the following message declarations:
+
+        message Profile {
+          User user = 1;
+          Photo photo = 2;
+        }
+        message User {
+          string display_name = 1;
+          string address = 2;
+        }
+
+    In proto a field mask for `Profile` may look as such:
+
+        mask {
+          paths: "user.display_name"
+          paths: "photo"
+        }
+
+    In JSON, the same mask is represented as below:
+
+        {
+          mask: "user.displayName,photo"
+        }
+
+    # Field Masks and Oneof Fields
+
+    Field masks treat fields in oneofs just as regular fields. Consider the
+    following message:
+
+        message SampleMessage {
+          oneof test_oneof {
+            string name = 4;
+            SubMessage sub_message = 9;
+          }
+        }
+
+    The field mask can be:
+
+        mask {
+          paths: "name"
+        }
+
+    Or:
+
+        mask {
+          paths: "sub_message"
+        }
+
+    Note that oneof type names ("test_oneof" in this case) cannot be used in
+    paths.
+
+    ## Field Mask Verification
+
+    The implementation of any API method which has a FieldMask type field in the
+    request should verify the included field paths, and return an
+    `INVALID_ARGUMENT` error if any path is unmappable.

+
+class Timestamp(google.protobuf.message.Message, google.protobuf.internal.well_known_types.Timestamp):
+    """A Timestamp represents a point in time independent of any time zone or local
+    calendar, encoded as a count of seconds and fractions of seconds at
+    nanosecond resolution. The count is relative to an epoch at UTC midnight on
+    January 1, 1970, in the proleptic Gregorian calendar which extends the
+    Gregorian calendar backwards to year one.
+
+    All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
+    second table is needed for interpretation, using a [24-hour linear
+    smear](https://developers.google.com/time/smear).
+
+    The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
+    restricting to that range, we ensure that we can convert to and from [RFC
+    3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
+
+    # Examples
+
+    Example 1: Compute Timestamp from POSIX `time()`.
+
+        Timestamp timestamp;
+        timestamp.set_seconds(time(NULL));
+        timestamp.set_nanos(0);
+
+    Example 2: Compute Timestamp from POSIX `gettimeofday()`.
+
+        struct timeval tv;
+        gettimeofday(&tv, NULL);
+
+        Timestamp timestamp;
+        timestamp.set_seconds(tv.tv_sec);
+        timestamp.set_nanos(tv.tv_usec * 1000);
+
+    Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
+
+        FILETIME ft;
+        GetSystemTimeAsFileTime(&ft);
+        UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
+
+        // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+        // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+        Timestamp timestamp;
+        timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
+        timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+
+    Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+
+        long millis = System.currentTimeMillis();
+
+        Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+            .setNanos((int) ((millis % 1000) * 1000000)).build();
+
+
+    Example 5: Compute Timestamp from Java `Instant.now()`.
+
+        Instant now = Instant.now();
+
+        Timestamp timestamp =
+            Timestamp.newBuilder().setSeconds(now.getEpochSecond())
+                .setNanos(now.getNano()).build();
+
+
+    Example 6: Compute Timestamp from current time in Python.
+
+        timestamp = Timestamp()
+        timestamp.GetCurrentTime()
+
+    # JSON Mapping
+
+    In JSON format, the Timestamp type is encoded as a string in the
+    [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+    format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+    where {year} is always expressed using four digits while {month}, {day},
+    {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+    seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+    are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+    is required. A proto3 JSON serializer should always use UTC (as indicated by
+    "Z") when printing the Timestamp type and a proto3 JSON parser should be
+    able to accept both UTC and other timezones (as indicated by an offset).
+
+    For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+    01:30 UTC on January 15, 2017.
+
+    In JavaScript, one can convert a Date object to this format using the
+    standard
+    [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+    method. In Python, a standard `datetime.datetime` object can be converted
+    to this format using
+    [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
+    the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
+    the Joda Time's [`ISODateTimeFormat.dateTime()`](
+    http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
+    ) to obtain a formatter capable of generating timestamps in this format.
