Cool class, Joe!

Never import "mac" directly, all its functionality is available from os. I
guess the docs aren't too clear about this. "mac" is the equivalent of the
posix module on unix, which you also shouldn't use directly.

Ah, here's another neat function from os.path which you could use instead:

			fpath = os.path.join(path, fname)

(it's cross platform, too!)
