4. Return the case of a filename in some arbitrarily-chosen canonical form which does not depend on the file system? This is what normpath does, but only if you're on Windows ;-) Not quite. macpath.normcase() also lowercases the path. So does the module for OS/2. Interesting, since I develop on MacOS, Linux and Windows and only experienced the problem caused by setuptools normcase'ing distribution names on Windows. The MacOS case also isn't in the docs.

Unless you're using Mac OS 9 you will be using posixpath and not macpath though. :-)
