"""Uninstaller for Windows NT 3.5 and Windows 95.
Actions:
1. Remove our entries from the Registry:
- Software\Python\PythonCore\<winver>
- Software\Microsoft\Windows\CurrentVersion\Uninstall\Python<winver>
(Should we also remove the entry for .py and Python.Script?)
2. Remove the installation tree -- this is assumed to be the directory
whose path is both os.path.dirname(sys.argv[0]) and sys.path[0]
