Using Clearcase functionality in CVS

[D.glover]

I'm forwarding an email from a coworker who is our configuration manager
and has a Clearcase background.  We however, use CVS in our office and
are attempting to implement some Clearcase techniques (features) in
CVS.  If you can provide any assistance in this area (Used both
Clearcase and CVS), your input would be greatly appreciated.  The
following inserted email explains what we are trying to accomplish.
