I've been working with the migration of the Emacs repository, and if *I*
had a CVS repository that I was going to migrate I wouldn't trust
anything but cvs2svn/cvs2git, unless I was willing to rework a lot of
the information by hand.  bzr fast-import works (and is the fastest of
the bzr importers), and cvs2git has a lot more real world testing behind
it than any other tool.  There are lots of ways to end up with a less
than perfect CVS repository and cvs2svn/cvs2git will sort most of them
out for you.

The Emacs repository that actually gets used is likely to be something
that was stitched together using git so that the merge information could
be included, but unless you have someone willing to do that sort of
surgery cvs2svn is really the way to go.

If you want, I suppose I could post that to the cvs2svn mailing list as
well.  You folks certainly deserve the kudos.
