Here's a very simple Python version scheme we've been using
with X.X being the major.minor Python version and Y being
either 2 or 4 depending on the UCS-build that was used to
build the egg.
The "_ucsY" part is not needed for pure-Python archives (but it
doesn't hurt using it there as well) and also not needed on
Windows, since Python is always UCS2 on Windows.
easy_install should first look for the full version string and
then fall back to the non-UCS one.
