Using subversion tools on Mozilla CVS

I found this tool written in Python for importing CVS into Subversion. It seems to be handling the Mozilla CVS repository with fewer problems than parsecvs.

http://cvs2svn.tigris.org/cvs2svn.html

Since I'm not a native Python speaker, anyone else want to give a try at changing it to support git?

It found these symbols to be ambiguous, so I manually forced them the way they look like they should be.
