In short, there are 2 sets of utilities. One is SCCS, which is standard for
UNIX and the other is RCS, which is free software and ftp-able from purdue.
(Actually I found RCS in local system.) After using both of them, I found
out RCS is more easy to use. (or at least manual is more easy to understand)
I am using RCS now and quite satisfied with it. 

Thank you again for all the info.
