-<# 
-.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:
