Perforce, Bitkeeper and Subversion are all "better-breed-CVS" solutions,
while I consider arch to be a "better-breed-revision-control-system".
Unfortunately it currently doesn't have an import mechanism that will keep
all your CVS history, so I understand that it is not an option at this
time.

However, it is a young project, having its first alpha release on Jan 16
of this year. At the current development pace, we may see the CVS import
functionality very soon. I have sent a question about this to Tom Lord.
