Summary: SCCS vs. RCS

[Donn Terry]

Item            SCCS                          RCS

speed           retrieve old versions faster  retrieve latest version faster

This isn't quite true:

SCCS:	Linear in the size of the SCCS file for any revision.
        (Retrieve any version in the same amount of time.)

RCS:    O(n), where n is the number of changes between the top and the
	requested version.  (Retrieve old versions very slowly.)

In practice, top revision is slightly faster (for the same history)
for RCS, but small enough in either case as to not really matter (a
few seconds at most; not enough time to think about the difference).
