heh..

OK: as some have pointed out, there *really* isn't a heck of a lot of
perl in this script.

I'm trying to learn perl, so I just use it for everything...

Also, my lawyer just about puked when she heard what I'd done, and she
wants me to add this:


			    NO WARRANTY

REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,

POSSIBILITY OF SUCH DAMAGES.

		     END OF TERMS AND CONDITIONS



And for this I pay her what?
