[.rcs]
RCS is Revision Control System. This is a software package designed
to control revisions of source code, allow controlled mods, and allow
return to any prior version or subversion. It is widely used with
many systems, and can also work with the CVS system (Concurrent
Versioning System) in the GNU distribution area. This is a VMS
port of RCS V4.3 complete with sources. Rich Gregory contributed it.
