Look at the man pages for rcs, cvs, etc.  I.e, consult the documentation
for one of these version control utilities.

Good.  What are you using?

           Interchange these arguments.  (You still get useful

Do a "man diff" for more info.

But, in a nutshell, the diff program shows you the list of differences
between two versions of a file or two directories with the same files.
You will probably want to use one or more option flags with diff because
by default, it produces output suitable for feeding into ed.  I
recommend "diff -up" for most purposes, but occassionally
"diff --side-by-side" is useful too.  (But do look at the documentation
for diff.  If you're not familiar with it already, you should be.  It
is an incredibly useful tool.)
