+<#
+.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:

+Jinja
+=====
+
+Jinja is a fast, expressive, extensible templating engine. Special
+placeholders in the template allow writing code similar to Python
+syntax. Then the template is passed data to render the final document.
+
+It includes:
+
+-   Template inheritance and inclusion.
+-   Define and import macros within templates.
+-   HTML templates can use autoescaping to prevent XSS from untrusted
+    user input.
+-   A sandboxed environment can safely render untrusted templates.
+-   AsyncIO support for generating templates and calling async
+    functions.
+-   I18N support with Babel.
+-   Templates are compiled to optimized Python code just-in-time and
+    cached, or can be compiled ahead-of-time.
+-   Exceptions point to the correct line in templates to make debugging
+    easier.
+-   Extensible filters, tests, functions, and even syntax.
+
+Jinja's philosophy is that while application logic belongs in Python if
+possible, it shouldn't make the template designer's job difficult by
+restricting functionality too much.
+
+
+Installing

+MarkupSafe
+==========
+
+MarkupSafe implements a text object that escapes characters so it is
+safe to use in HTML and XML. Characters that have special meanings are
+replaced so that they display as the actual characters. This mitigates
+injection attacks, meaning untrusted user input can safely be displayed
+on a page.
+
+
+Installing
+----------
+
+Install and update using `pip`_:
+
+.. code-block:: text
+
+    pip install -U MarkupSafe
+
+.. _pip: https://pip.pypa.io/en/stable/quickstart/
+
+
+Examples
+--------
+
+.. code-block:: pycon
+
+    >>> from markupsafe import Markup, escape
+    >>> # escape replaces special characters and wraps in Markup
+    >>> escape('<script>alert(document.cookie);</script>')
+    Markup(u'&lt;script&gt;alert(document.cookie);&lt;/script&gt;')
+    >>> # wrap in Markup to mark text "safe" and prevent escaping
+    >>> Markup('<strong>Hello</strong>')
+    Markup('<strong>hello</strong>')
+    >>> escape(Markup('<strong>Hello</strong>'))
+    Markup('<strong>hello</strong>')
+    >>> # Markup is a text subclass (str on Python 3, unicode on Python 2)
+    >>> # methods and operators escape their arguments
+    >>> template = Markup("Hello <em>%s</em>")
+    >>> template % '"World"'
+    Markup('Hello <em>&#34;World&#34;</em>')

+Description: YAML is a data serialization format designed for human readability
+        and interaction with scripting languages.  PyYAML is a YAML parser
+        and emitter for Python.
+        
+        PyYAML features a complete YAML 1.1 parser, Unicode support, pickle
+        support, capable extension API, and sensible error messages.  PyYAML
+        supports standard YAML tags and provides Python-specific tags that
+        allow to represent an arbitrary Python object.
+        
+        PyYAML is applicable for a broad range of tasks from complex
+        configuration files to object serialization and persistence.

+          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

+          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

+Key Features
+============
+
+- Supports both client and server side of HTTP protocol.
+- Supports both client and server Web-Sockets out-of-the-box and avoids
+  Callback Hell.
+- Provides Web-server with middlewares and plugable routing.
+
+
+Getting started
+===============
+
+Client
+------
+
+To get something from the web:
+
+.. code-block:: python
+
+  import aiohttp
+  import asyncio
+
+  async def main():
+
+      async with aiohttp.ClientSession() as session:
+          async with session.get('http://python.org') as response:
+
+              print("Status:", response.status)
+              print("Content-type:", response.headers['content-type'])
+
+              html = await response.text()
+              print("Body:", html[:15], "...")
+
+  loop = asyncio.get_event_loop()
+  loop.run_until_complete(main())
+
+This prints:
+
+.. code-block::
+
+    Status: 200
+    Content-type: text/html; charset=utf-8
+    Body: <!doctype html> ...
+
+Coming from `requests <https://requests.readthedocs.io/>`_ ? Read `why we need so many lines <https://aiohttp.readthedocs.io/en/latest/http_request_lifecycle.html>`_.
+
+Server
+------
+
+An example using a simple server:
+
+.. code-block:: python
+
+    # examples/server_simple.py
+    from aiohttp import web
+
+    async def handle(request):
+        name = request.match_info.get('name', "Anonymous")
+        text = "Hello, " + name
+        return web.Response(text=text)
+
+    async def wshandle(request):
+        ws = web.WebSocketResponse()
+        await ws.prepare(request)
+
+        async for msg in ws:
+            if msg.type == web.WSMsgType.text:
+                await ws.send_str("Hello, {}".format(msg.data))
+            elif msg.type == web.WSMsgType.binary:
+                await ws.send_bytes(msg.data)
+            elif msg.type == web.WSMsgType.close:
+                break
+
+        return ws
+
+
+    app = web.Application()
+    app.add_routes([web.get('/', handle),
+                    web.get('/echo', wshandle),
+                    web.get('/{name}', handle)])
+
+    if __name__ == '__main__':
+        web.run_app(app)

+  `#4528 <https://github.com/aio-libs/aiohttp/issues/4528>`_
+- Fix connecting to link-local IPv6 addresses.
+  `#4554 <https://github.com/aio-libs/aiohttp/issues/4554>`_

+- Always make sure transport is not closing before reuse a connection.
+
+  Reuse a protocol based on keepalive in headers is unreliable.
+  For example, uWSGI will not support keepalive even it serves a
+  HTTP 1.1 request, except explicitly configure uWSGI with a
+  ``--http-keepalive`` option.
+
+  Servers designed like uWSGI could cause aiohttp intermittently
+  raise a ConnectionResetException when the protocol poll runs
+  out and some protocol is reused.
+  `#4587 <https://github.com/aio-libs/aiohttp/issues/4587>`_
+- Handle the last CRLF correctly even if it is received via separate TCP segment.

+  `#4691 <https://github.com/aio-libs/aiohttp/issues/4691>`_
+- Improve typing annotations for ``web.Request``, ``aiohttp.ClientResponse`` and
+  ``multipart`` module.
+  `#4736 <https://github.com/aio-libs/aiohttp/issues/4736>`_
+- Fix resolver task is not awaited when connector is cancelled
+  `#4795 <https://github.com/aio-libs/aiohttp/issues/4795>`_
+- Fix a bug "Aiohttp doesn't return any error on invalid request methods"
+  `#4798 <https://github.com/aio-libs/aiohttp/issues/4798>`_
+- Fix HEAD requests for static content.
+  `#4809 <https://github.com/aio-libs/aiohttp/issues/4809>`_
+- Fix incorrect size calculation for memoryview
+  `#4890 <https://github.com/aio-libs/aiohttp/issues/4890>`_
+- Add HTTPMove to _all__.
+  `#4897 <https://github.com/aio-libs/aiohttp/issues/4897>`_
+- Fixed the type annotations in the ``tracing`` module.
+  `#4912 <https://github.com/aio-libs/aiohttp/issues/4912>`_
+- Fix typing for multipart ``__aiter__``.
+  `#4931 <https://github.com/aio-libs/aiohttp/issues/4931>`_
