+
+
+``cryptography`` is a package which provides cryptographic recipes and
+primitives to Python developers. Our goal is for it to be your "cryptographic
+standard library". It supports Python 3.7+ and PyPy3 7.3.11+.
+
+``cryptography`` includes both high level recipes and low level interfaces to
+common cryptographic algorithms such as symmetric ciphers, message digests, and
+key derivation functions. For example, to encrypt something with
+``cryptography``'s high level symmetric encryption recipe:
+
+.. code-block:: pycon
+
+    >>> from cryptography.fernet import Fernet
+    >>> # Put this somewhere safe!
+    >>> key = Fernet.generate_key()
+    >>> f = Fernet(key)
+    >>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
+    >>> token
+    b'...'
+    >>> f.decrypt(token)
+    b'A really secret message. Not for prying eyes.'
+
+You can find more information in the `documentation`_.
+
+You can install ``cryptography`` with:
+
+.. code-block:: console
+
+    $ pip install cryptography
+
+For full details see `the installation documentation`_.
+
+Discussion
+~~~~~~~~~~
+
+If you run into bugs, you can file them in our `issue tracker`_.
+
+We maintain a `cryptography-dev`_ mailing list for development discussion.
+
+You can also join ``#pyca`` on ``irc.libera.chat`` to ask questions or get
+involved.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      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.
+
+   END OF TERMS AND CONDITIONS

+          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

+          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.

+}
+```
+
+
+## Python API
+
+Find the Python API documentation at [csvw.readthedocs.io](https://csvw.readthedocs.io/en/latest/).
+
+A quick example for using `csvw` from Python code:
+
+```python
+import json
+from csvw import CSVW
+data = CSVW('https://raw.githubusercontent.com/cldf/csvw/master/tests/fixtures/test.tsv')
+print(json.dumps(data.to_json(minimal=True), indent=4))
+[
+    {
+        "province": "Hello",
+        "territory": "world",
+        "precinct": "1"
+    }
+]
+```
+
+
+## Known limitations
+
+- We read **all** data which is specified as UTF-8 encoded using the 
+  [`utf-8-sig` codecs](https://docs.python.org/3/library/codecs.html#module-encodings.utf_8_sig).
+  Thus, if such data starts with `U+FEFF` this will be interpreted as [BOM](https://en.wikipedia.org/wiki/Byte_order_mark)
+  and skipped.
+- Low level CSV parsing is delegated to the `csv` module in Python's standard library. Thus, if a `commentPrefix`
+  is specified in a `Dialect` instance, this will lead to skipping rows where the first value starts
+  with `commentPrefix`, **even if the value was quoted**.
+- Also, cell content containing `escapechar` may not be round-tripped as expected (when specifying
+  `escapechar` or a `csvw.Dialect` with `quoteChar` but `doubleQuote==False`),
+  when minimal quoting is specified. This is due to inconsistent `csv` behaviour
+  across Python versions (see https://bugs.python.org/issue44861).
+
+
+## CSVW conformance
+
+While we use the CSVW specification as guideline, this package does not (and 
+probably never will) implement the full extent of this spec.
+
+- When CSV files with a header are read, columns are not matched in order with
+  column descriptions in the `tableSchema`, but instead are matched based on the
+  CSV column header and the column descriptions' `name` and `titles` atributes.
+  This allows for more flexibility, because columns in the CSV file may be
+  re-ordered without invalidating the metadata. A stricter matching can be forced
+  by specifying `"header": false` and `"skipRows": 1` in the table's dialect
+  description.
+
+However, `csvw.CSVW` works correctly for
+- 269 out of 270 [JSON tests](https://w3c.github.io/csvw/tests/#manifest-json),
+- 280 out of 282 [validation tests](https://w3c.github.io/csvw/tests/#manifest-validation),
+- 10 out of 18 [non-normative tests](https://w3c.github.io/csvw/tests/#manifest-nonnorm)
+
+from the [CSVW Test suites](https://w3c.github.io/csvw/tests/).
+
+
+## Compatibility with [Frictionless Data Specs](https://specs.frictionlessdata.io/)
+
+A CSVW-described dataset is basically equivalent to a Frictionless DataPackage where all 
+[Data Resources](https://specs.frictionlessdata.io/data-resource/) are [Tabular Data](https://specs.frictionlessdata.io/tabular-data-resource/).
+Thus, the `csvw` package provides some conversion functionality. To
+"read CSVW data from a Data Package", there's the `csvw.TableGroup.from_frictionless_datapackage` method:
+```python
+from csvw import TableGroup
+tg = TableGroup.from_frictionless_datapackage('PATH/TO/datapackage.json')
+```
+To convert the metadata, the `TableGroup` can then be serialzed:
+```python
+tg.to_file('csvw-metadata.json')
+```
+
+Note that the CSVW metadata file must be written to the Data Package's directory
+to make sure relative paths to data resources work.
+
+This functionality - together with the schema inference capabilities
+of [`frictionless describe`](https://framework.frictionlessdata.io/docs/guides/describing-data/) - provides
+a convenient way to bootstrap CSVW metadata for a set of "raw" CSV
+files, implemented in the [`csvwdescribe` command described above](#csvwdescribe).

+
+    An instance of this class provides the files residing within a remote github

+    or tag (default is current master).
+
+    Given that code files tend to be small, and that github does not support
+    retrieving partial content, we always fetch whole files.
+
+    When using fsspec.open, allows URIs of the form:
+
+    - "github://path/file", in which case you must specify org, repo and
+      may specify sha in the extra args
+    - 'github://org:repo@/precip/catalog.yml', where the org and repo are
+      part of the URI
+    - 'github://org:repo@sha/precip/catalog.yml', where the sha is also included
+
+    ``sha`` can be the full or abbreviated hex of the commit you want to fetch
+    from, or a branch or tag name (so long as it doesn't contain special characters
+    like "/", "?", which would have to be HTTP-encoded).

+iniconfig: brain-dead simple parsing of ini files
+=======================================================
+
+iniconfig is a small and simple INI-file parser module
+having a unique set of features:
+
+* maintains order of sections and entries
+* supports multi-line values with or without line-continuations
+* supports "#" comments everywhere
+* raises errors with proper line-numbers
+* no bells and whistles like automatic substitutions
+* iniconfig raises an Error if two sections have the same name.
+
+If you encounter issues or have feature wishes please report them to:
+
+    https://github.com/RonnyPfannschmidt/iniconfig/issues
+
+Basic Example
+===================================
+
+If you have an ini file like this:
+
+.. code-block:: ini
+
+    # content of example.ini
+    [section1] # comment
+    name1=value1  # comment
+    name1b=value1,value2  # comment
+
+    [section2]
+    name2=
+        line1
+        line2
+
+then you can do:
+
+.. code-block:: pycon
+
+    >>> import iniconfig
+    >>> ini = iniconfig.IniConfig("example.ini")
+    >>> ini['section1']['name1'] # raises KeyError if not exists
+    'value1'
+    >>> ini.get('section1', 'name1b', [], lambda x: x.split(","))
+    ['value1', 'value2']
+    >>> ini.get('section1', 'notexist', [], lambda x: x.split(","))
+    []
+    >>> [x.name for x in list(ini)]
+    ['section1', 'section2']
+    >>> list(list(ini)[0].items())
+    [('name1', 'value1'), ('name1b', 'value1,value2')]
+    >>> 'section1' in ini
+    True
+    >>> 'inexistendsection' in ini
+    False

+multiprocess: better multiprocessing and multithreading in python
+-----------------------------------------------------------------
+
+About Multiprocess
+====================
+
+``multiprocess`` is a fork of ``multiprocessing``, and is developed as part of ``pathos``: 
+https://github.com/uqfoundation/pathos
+
+``multiprocessing`` is a package for the Python language which supports the
+spawning of processes using the API of the standard library's
+``threading`` module. ``multiprocessing`` has been distributed in the standard
+library since python 2.6.
+
+Features:
+
+    - Objects can be transferred between processes using pipes or multi-producer/multi-consumer queues.
+    - Objects can be shared between processes using a server process or (for simple data) shared memory.
+    - Equivalents of all the synchronization primitives in ``threading`` are available.
+    - A ``Pool`` class makes it easy to submit tasks to a pool of worker processes.
+
+
+``multiprocess`` is part of ``pathos``,  a python framework for heterogeneous computing.
+``multiprocess`` is in active development, so any user feedback, bug reports, comments,
+or suggestions are highly appreciated.  A list of issues is located at https://github.com/uqfoundation/multiprocess/issues, with a legacy list maintained at https://uqfoundation.github.io/project/pathos/query.
+
+NOTE: A C compiler is required to build the included extension module. For python 3.3 and above, a C compiler is suggested, but not required.
+
+
+Major Changes
+==============
+
+    - enhanced serialization, using ``dill``
+
+
+Current Release
+===============
+
+This documentation is for version ``multiprocess-0.70.12.2`` (a fork of ``multiprocessing-0.70a1``).
+
+The latest released version of ``multiprocess`` is available from::
+
+    https://pypi.org/project/multiprocess
+
+``Multiprocessing`` is distributed under a BSD license.
+
+
+Development Version
+===================
+
+You can get the latest development version with all the shiny new features at::
+
+    https://github.com/uqfoundation
+
+If you have a new contribution, please submit a pull request.
+
+
+Installation
+============
+
+``multiprocess`` is packaged to install from source, so you must
+download the tarball, unzip, and run the installer::
+
+    [download]
+    $ tar -xvzf multiprocess-0.70.12.2.tgz
+    $ cd multiprocess-0.70.12.2
+    $ python setup.py build
+    $ python setup.py install
+
+You will be warned of any missing dependencies and/or settings
+after you run the "build" step above.
+
+Alternately, ``multiprocess`` can be installed with ``pip`` or ``easy_install``::
+
+    $ pip install multiprocess
+
+NOTE: A C compiler is required to build the included extension module from source. For python 3.3 and above, a C compiler is suggested, but not required. Binary installs do not require a C compiler.
+
+
+Requirements
+============
+
+``multiprocess`` requires::
+
+    - ``python``, **version == 2.7** or **version >= 3.6**, or ``pypy``
+    - ``dill``, **version >= 0.3.4**
+
+Optional requirements::
+
+    - ``setuptools``, **version >= 0.6**
+
+
+Basic Usage
+===========
+
+The ``multiprocess.Process`` class follows the API of ``threading.Thread``.
+For example ::
+
+    from multiprocess import Process, Queue
+
+    def f(q):
+        q.put('hello world')
+
+    if __name__ == '__main__':
+        q = Queue()
+        p = Process(target=f, args=[q])
+        p.start()
+        print (q.get())
+        p.join()
+
+Synchronization primitives like locks, semaphores and conditions are
+available, for example ::
+
+    >>> from multiprocess import Condition
+    >>> c = Condition()
+    >>> print (c)
+    <Condition(<RLock(None, 0)>), 0>
+    >>> c.acquire()
+    True
+    >>> print (c)
+    <Condition(<RLock(MainProcess, 1)>), 0>
+
+One can also use a manager to create shared objects either in shared
+memory or in a server process, for example ::
+
+    >>> from multiprocess import Manager
+    >>> manager = Manager()
+    >>> l = manager.list(range(10))
+    >>> l.reverse()
+    >>> print (l)
+    [9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
+    >>> print (repr(l))
+    <Proxy[list] object at 0x00E1B3B0>
+
+Tasks can be offloaded to a pool of worker processes in various ways,
+for example ::
+
+    >>> from multiprocess import Pool
+    >>> def f(x): return x*x
+    ...
+    >>> p = Pool(4)
+    >>> result = p.map_async(f, range(10))
+    >>> print (result.get(timeout=1))
+    [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]
+
+When ``dill`` is installed, serialization is extended to most objects,
+for example ::
+
+    >>> from multiprocess import Pool
+    >>> p = Pool(4)
+    >>> print (p.map(lambda x: (lambda y:y**2)(x) + x, xrange(10)))
+    [0, 2, 6, 12, 20, 30, 42, 56, 72, 90]
+
+
+More Information
+================
+
+Probably the best way to get started is to look at the documentation at
+http://multiprocess.rtfd.io. See ``multiprocess.examples`` for a set of example
+scripts. You can also run the test suite with ``python -m multiprocess.tests``.
+Please feel free to submit a ticket on github, or ask a question on
+stackoverflow (**@Mike McKerns**).  If you would like to share how you use
+``multiprocess`` in your work, please post send an email
+(to **mmckerns at uqfoundation dot org**).
