Fair point. (Although I don't recall your distutils-sig posting, so
I'm not sure what you mean by "name canonicalisation").

Note that even on case insensitive filesystems, module/package names
are handled case sensitively. I would be happy to see distribution
names handled the same (although I have no vested interest either
way).

Is there code around to handle filename matching based on the case
sensitivity of the filesystem? (My understanding is that there isn't,
and programs like Mercurial play fancy games to determine if a
filesystem is case sensitive before doing tests). Of course, if you're
OK with an inaccurate but simple choice based on OS, it would probably
be OK to use os.path.normcase.

Paul.
