SCCS vs RCS

[Mark D. McKamey IM SA]

Hello,
 
     I am currently looking into implementing a revision control program
for numerous source files here locally.  I am somewhat familiar with AT&T's
SCCS program, but have heard of a program called RCS (Revision Control System)
by Purdue University.  What I am looking for is a detailed comparision
between SCCS and RCS.  Any information concerning such comparison would be
greatly appreciated.  Thank You,
