I should have mentioned, I've been assuming that it's simply impossible 
to run this on Windows, since it requires FontForge, which is *nix down 
to the toes. It should "just work" on Cygwin, but Cygwin users will find 
that the standard FontForge install has no Python support at all; so 
they must either build from source or just forget it.

I'm afraid it's just Mac and Linux.
