If I had to start over, I'd be happy to consider arch (and Perforce,
and Bitkeeper, and, oh, why not, Subversion).  As it is, this would
mean ripping out the foundation from our development process --
everything we do is tied to CVS on SF.  So, unless arch runs on top
of an existing CVS setup, too bad.
