 From my understanding, piping data to git fast-import would be
a sane gateway to git. The input format of fast-import is document
in [1].

Maybe Shaw Pearce has some comments on that. Shawn did most
(maybe all) of the work on git-fast-import.

Simon Hausmann wrote a p4 importer that uses fast-import as
its backend. Maybe, Simon can give hints how to get started.

I have no experience with neither git-fast-import nor the p4
importer but would be happy to test any improved way of importing
cvs to git. I experienced problems using git-cvsimport on a rather
large cvs repository. Hence it would be a real test of the superior
capabilities of cvs2svn.
