+<#
+.Synopsis
+Activate a Python virtual environment for the current PowerShell session.
+
+.Description
+Pushes the python executable for a virtual environment to the front of the
+$Env:PATH environment variable and sets the prompt to signify that you are
+in a Python virtual environment. Makes use of the command line switches as
+well as the `pyvenv.cfg` file values present in the virtual environment.
+
+.Parameter VenvDir
+Path to the directory that contains the virtual environment to activate. The
+default value for this is the parent of the directory that the Activate.ps1
+script is located within.
+
+.Parameter Prompt
+The prompt prefix to display when this virtual environment is activated. By
+default, this prompt is the name of the virtual environment folder (VenvDir)
+surrounded by parentheses and followed by a single space (ie. '(.venv) ').
+
+.Example
+Activate.ps1
+Activates the Python virtual environment that contains the Activate.ps1 script.
+
+.Example
+Activate.ps1 -Verbose
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and shows extra information about the activation as it executes.
+
+.Example
+Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
+Activates the Python virtual environment located in the specified location.
+
+.Example
+Activate.ps1 -Prompt "MyPython"
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and prefixes the current prompt with the specified string (surrounded in
+parentheses) while the virtual environment is active.
+
+.Notes
+On Windows, it may be required to enable this Activate.ps1 script by setting the
+execution policy for the user. You can do this by issuing the following PowerShell
+command:
+
+PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+
+For more information on Execution Policies:

+
+The async_generator library
+===========================
+
+Python 3.6 added `async generators
+<https://www.python.org/dev/peps/pep-0525/>`__. (What's an async
+generator? `Check out my 5-minute lightning talk demo from PyCon 2016
+<https://youtu.be/PulzIT8KYLk?t=24m30s>`__.) Python 3.7 adds some more
+tools to make them usable, like ``contextlib.asynccontextmanager``.
+
+This library gives you all that back to Python 3.5.
+
+For example, this code only works in Python 3.6+:
+
+.. code-block:: python3
+
+   async def load_json_lines(stream_reader):
+       async for line in stream_reader:
+           yield json.loads(line)
+
+But this code does the same thing, and works on Python 3.5+:
+
+.. code-block:: python3
+
+   from async_generator import async_generator, yield_
+
+   @async_generator
+   async def load_json_lines(stream_reader):
+       async for line in stream_reader:
+           await yield_(json.loads(line))
+
+Or in Python 3.7, you can write:
+
+.. code-block:: python3
+
+   from contextlib import asynccontextmanager
+
+   @asynccontextmanager
+   async def background_server():
+       async with trio.open_nursery() as nursery:
+           value = await nursery.start(my_server)
+           try:
+               yield value
+           finally:
+               # Kill the server when the scope exits
+               nursery.cancel_scope.cancel()
+
+This is the same, but back to 3.5:
+
+.. code-block:: python3
+
+   from async_generator import async_generator, yield_, asynccontextmanager
+
+   @asynccontextmanager
+   @async_generator
+   async def background_server():
+       async with trio.open_nursery() as nursery:
+           value = await nursery.start(my_server)
+           try:
+               await yield_(value)
+           finally:
+               # Kill the server when the scope exits
+               nursery.cancel_scope.cancel()
+
+(And if you're on 3.6, you can use ``@asynccontextmanager`` with
+native generators.)
+
+
+Let's do this
+=============
+
+* Install: ``python3 -m pip install -U async_generator`` (or on Windows,
+  maybe ``py -3 -m pip install -U async_generator``
+
+* Manual: https://async-generator.readthedocs.io/
+
+* Bug tracker and source code: https://github.com/python-trio/async_generator
+
+* Real-time chat: https://gitter.im/python-trio/general
+
+* License: MIT or Apache 2, your choice
+
+* Contributor guide: https://trio.readthedocs.io/en/latest/contributing.html
+
+* Code of conduct: Contributors are requested to follow our `code of
+  conduct
+  <https://trio.readthedocs.io/en/latest/code-of-conduct.html>`__ in
+  all project spaces.
+
+
+How come some of those links talk about "trio"?
+===============================================
+
+`Trio <https://trio.readthedocs.io>`__ is a new async concurrency
+library for Python that's obsessed with usability and correctness – we
+want to make it *easy* to get things *right*. The ``async_generator``
+library is maintained by the Trio project as part of that mission, and
+because Trio uses ``async_generator`` internally.
+
+You can use ``async_generator`` with any async library. It works great
+with ``asyncio``, or Twisted, or whatever you like. (But we think Trio
+is pretty sweet.)

+======================================
+``attrs``: Classes Without Boilerplate
+======================================
+
+
+``attrs`` is the Python package that will bring back the **joy** of **writing classes** by relieving you from the drudgery of implementing object protocols (aka `dunder <https://nedbatchelder.com/blog/200605/dunder.html>`_ methods).
+`Trusted by NASA <https://docs.github.com/en/github/setting-up-and-managing-your-github-profile/personalizing-your-profile#list-of-qualifying-repositories-for-mars-2020-helicopter-contributor-badge>`_ for Mars missions since 2020!
+
+Its main goal is to help you to write **concise** and **correct** software without slowing down your code.
+
+.. teaser-end
+
+For that, it gives you a class decorator and a way to declaratively define the attributes on that class:
+
+.. -code-begin-
+
+.. code-block:: pycon
+
+   >>> import attr
+
+   >>> @attr.s
+   ... class SomeClass(object):
+   ...     a_number = attr.ib(default=42)
+   ...     list_of_numbers = attr.ib(factory=list)
+   ...
+   ...     def hard_math(self, another_number):
+   ...         return self.a_number + sum(self.list_of_numbers) * another_number
+
+
+   >>> sc = SomeClass(1, [1, 2, 3])
+   >>> sc
+   SomeClass(a_number=1, list_of_numbers=[1, 2, 3])
+
+   >>> sc.hard_math(3)
+   19
+   >>> sc == SomeClass(1, [1, 2, 3])
+   True
+   >>> sc != SomeClass(2, [3, 2, 1])
+   True
+
+   >>> attr.asdict(sc)
+   {'a_number': 1, 'list_of_numbers': [1, 2, 3]}
+
+   >>> SomeClass()
+   SomeClass(a_number=42, list_of_numbers=[])
+
+   >>> C = attr.make_class("C", ["a", "b"])
+   >>> C("foo", "bar")
+   C(a='foo', b='bar')
+
+
+After *declaring* your attributes ``attrs`` gives you:
+
+- a concise and explicit overview of the class's attributes,
+- a nice human-readable ``__repr__``,
+- a complete set of comparison methods (equality and ordering),
+- an initializer,
+- and much more,
+
+*without* writing dull boilerplate code again and again and *without* runtime performance penalties.
+
+On Python 3.6 and later, you can often even drop the calls to ``attr.ib()`` by using `type annotations <https://www.attrs.org/en/latest/types.html>`_.
+
+This gives you the power to use actual classes with actual types in your code instead of confusing ``tuple``\ s or `confusingly behaving <https://www.attrs.org/en/stable/why.html#namedtuples>`_ ``namedtuple``\ s.
+Which in turn encourages you to write *small classes* that do `one thing well <https://www.destroyallsoftware.com/talks/boundaries>`_.
+Never again violate the `single responsibility principle <https://en.wikipedia.org/wiki/Single_responsibility_principle>`_ just because implementing ``__init__`` et al is a painful drag.

+Release Information
+===================
+
+21.2.0 (2021-05-07)
+-------------------
+
+Backward-incompatible Changes
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- We had to revert the recursive feature for ``attr.evolve()`` because it broke some use-cases -- sorry!
+  `#806 <https://github.com/python-attrs/attrs/issues/806>`_
+- Python 3.4 is now blocked using packaging metadata because ``attrs`` can't be imported on it anymore.
+  To ensure that 3.4 users can keep installing  ``attrs`` easily, we will `yank <https://pypi.org/help/#yanked>`_ 21.1.0 from PyPI.
+  This has **no** consequences if you pin ``attrs`` to 21.1.0.
+  `#807 <https://github.com/python-attrs/attrs/issues/807>`_
+
+`Full changelog <https://www.attrs.org/en/stable/changelog.html>`_.

+Certifi: Python SSL Certificates
+================================
+
+`Certifi`_ provides Mozilla's carefully curated collection of Root Certificates for
+validating the trustworthiness of SSL certificates while verifying the identity
+of TLS hosts. It has been extracted from the `Requests`_ project.
+
+Installation
+------------
+
+``certifi`` is available on PyPI. Simply install it with ``pip``::
+
+    $ pip install certifi
+
+Usage
+-----
+
+To reference the installed certificate authority (CA) bundle, you can use the
+built-in function::
+
+    >>> import certifi
+
+    >>> certifi.where()
+    '/usr/local/lib/python3.7/site-packages/certifi/cacert.pem'
+
+Or from the command line::
+
+    $ python -m certifi
+    /usr/local/lib/python3.7/site-packages/certifi/cacert.pem
+
+Enjoy!
+
+1024-bit Root Certificates
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Browsers and certificate authorities have concluded that 1024-bit keys are
+unacceptably weak for certificates, particularly root certificates. For this
+reason, Mozilla has removed any weak (i.e. 1024-bit key) certificate from its
+bundle, replacing it with an equivalent strong (i.e. 2048-bit or greater key)
+certificate from the same CA. Because Mozilla removed these certificates from
+its bundle, ``certifi`` removed them as well.
+
+In previous versions, ``certifi`` provided the ``certifi.old_where()`` function
+to intentionally re-add the 1024-bit roots back into your bundle. This was not
+recommended in production and therefore was removed at the end of 2018.
+
+.. _`Certifi`: https://certifiio.readthedocs.io/en/latest/
+.. _`Requests`: https://requests.readthedocs.io/en/master/
+
+Addition/Removal of Certificates
+--------------------------------
+
+Certifi does not support any addition/removal or other modification of the
+CA trust store content. This project is intended to provide a reliable and
+highly portable root of trust to python deployments. Look to upstream projects
+for methods to use alternate trust.
+
+
