Add PowerShell support via virtualenvwrapper.ps1

[isa-murat]

Summary

This pull request introduces PowerShell support for the virtualenvwrapper functionality, allowing Windows users to manage their virtual environments using familiar commands (mkvirtualenv, workon, rmvirtualenv) in PowerShell.

Changes Made

• Added virtualenvwrapper.ps1 script for PowerShell support
• Updated README.rst with installation and usage instructions

Why?

Currently, the project supports only Unix-like shells. Adding PowerShell compatibility improves cross-platform usability and makes it easier for Windows developers to adopt the tool.

Notes

This implementation intentionally does not redefine Python’s built-in deactivate command. Users can still use the standard deactivate provided by venv.

Hi @isa-murat , this is certainly interesting as a proof-of-concept, but as it currently stands it is very incomplete (run virtualenvwrapper in a dos-shell for all the commands). It also doesn't have any tests... (see the tests/ directory for the current test-suite). There is also the issue of maintenance. Dos-scripts are particularly horrible to debug and few people are interested in maintaining a dos/bat code base. I don't use powershell so... Perhaps this is better suited as a separate package? If you think this is a better idea (and you need help setting it up) I'll be more than happy to help.
