I've used cvs20hg with a moderate amount of success.

Repo-copies and repo-moves confuse cvs20hg some times, though.

I did manage to convert the entire doc/ tree which is not branched,
and that worked much better.  The converted tree lives at:

    http://hg.hellug.gr/freebsd/doc

and I semi-regularly push incrementally converted changesets to that.

The ports/ tree is so immensely huge, and there are so many repo-copies,
repo-moves and other CVS 'hacks' that I haven't found the time to run a
conversion for all of it.
