One caveat: if you use wxPython, wxversion.select() pushes the directory
containing the selected version at the front of sys.path, so that a
subsequent "import wx" will import the correct version.

It's possible that other functions may do likewise, so if you're
relying upon sys.path[0] to find the script's directory, it's a good idea
to make a copy of sys.path[0] before importing any modules (other than sys).
