Another way to do it (thanks to Matthew Melvin

The ident command (which is part of the RCS package) can be used to extract
keywords and their values from a file. This can be handy for text files, but
it is even more useful for extracting keywords from binary files.
$ ident samp.c
samp.c:
$Id: samp.c,v 1.5 1993/10/19 14:57:32 ceder Exp $
$ gcc samp.c
$ ident a.out
a.out:
$Id: samp.c,v 1.5 1993/10/19 14:57:32 ceder Exp $
SCCS is another popular revision control system. It has a command, what,
which is very similar to ident and used for the same purpose. Many sites
without RCS have SCCS. Since what looks for the character sequence @(#) it
is easy to include keywords that are detected by either command. Simply
prefix the RCS keyword with the magic SCCS phrase, like this:
static char *id="@(#) $Id: ab.c,v 1.5 1993/10/19 14:57:32 ceder Exp $";
