-.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:

-Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the
-given folder, and returns them in a map.
-
-For each line in the pyvenv.cfg file, if that line can be parsed into exactly
-two strings separated by `=` (with any amount of whitespace surrounding the =)
-then it is considered a `key = value` line. The left hand string is the key,
-the right hand is the value.
-
-If the value starts with a `'` or a `"` then the first and last character is
-stripped from the value before being captured.

-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!
-
-.. _`Requests`: https://requests.readthedocs.io/en/latest/
-
-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.
