-<#
-.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: 
-https://go.microsoft.com/fwlink/?LinkID=135170

-## Example
-
-Signal receivers can subscribe to specific senders or receive signals
-sent by any sender.
-
-```pycon
->>> from blinker import signal
->>> started = signal('round-started')
->>> def each(round):
-...     print(f"Round {round}")
-...
->>> started.connect(each)
-
->>> def round_two(round):
-...     print("This is round two.")
-...
->>> started.connect(round_two, sender=2)
-
->>> for round in range(1, 4):
-...     started.send(round)
-...
-Round 1!
-Round 2!
-This is round two.
-Round 3!
-```

-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::

-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.

-It contains the certificates in PEM format and therefore
