Incidentally, now that cvs2svn 2.0.0 is nearly out, I am thinking about what it would take to write some other back ends for cvs2svn-- turning it, essentially, into cvs2xxx. Most of the work that cvs2svn does is inferring the most plausible history of the repository from CVS's sketchy, incomplete, idiomatic, and often corrupt data. This work should also be useful for a cvs2git or cvs2hg or cvs2baz or ...Great to hear that. I'm game if we can do something in this direction - surely we can make it talk to fastimport ;-)We added some hooks to cvs2svn 2.0 to start working in this direction. But I don't really know what information is needed for a git import. One quick-and-dirty idea that I had was to have cvs2svn output information compatible with cvsps's output, as I believe that several tools rely on cvsps to do the dirty work and so could perhaps be persuaded to use cvs2svn out of the box.
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.
