title: Is there any documentation on the package.json file?
body: <p>Here's an instance of the <em>package.json</em> file that express.js generates</p>
  
  <pre><code>{
      "name": "packagename",
      "version": "0.0.1",
      "private": true,
      "dependencies": {
          "express": "2.5.5",
          "stylus": "0.22.2"
      }
  }
  </code></pre>
  
  <p>It's fairly obvious that I can add packages to the dependencies object. However I have no idea what <code>"private": true</code> means. Nor do I know what syntax I can use in the dependencies value fields. I've Googled for quite a while without discovering anything.</p>
  
  <p>What I'm wondering is pretty much if a complete summary of all settings that the <em>package.json</em> file can contain exists, as I could not find one. I haven't checked <code>man</code> since I'm on a windows PC.</p>
  
  <p>Thanks</p>
