And people complain about *Perl* being line noise?  If you're doing
option parsing, IMO, it's a *lot* easier to use getopt, whicn is a
bash built-in than arcane and confusing bash magic like this...

Not only would using getopt be more readable (and therefore less
confusing), but probably more maintainable in the long run as well...
