Meta-CVS is a new version control system based on CVS. It seems to be designed to be CVS plus a few new features that improve things that suck about CVS. The lack of grand ambition here may be the key to its success. Besides, how can you argue with a guarantee like this one:

If you are not fully satisfied with Meta-CVS for any reason, simply change to your installation directory and type “rm mcvs*”. Your disk space will be promptly refunded. No questions asked (unless you use rm -i, of course).
