Can't find Python 3.3 on Windows
Running tox on Windows 7 with Python 3.3b1 installed at c:\Python3.3, tox simply reports:
ERROR: py33: InterpreterNotFound: python3.3
I notice in _venv.py is win32map, which is an explicit mapping from versions to installations, but doesn't include 3.3. Perhaps this mapping could be generalized?
