[Israel.pm] Cool usage hack which I saw in another mailing list

I've seen this type of usage in several older Perl scripts. I think
that when I learned Perl in 1994, having been converted from awk and
bourne scripts, this was how I first saw usage messages embedded in
the scripts. I am sure it is a carryover from shell scripts, which did
a grep of the script file.
