It's worse than useless :-) ... it looks like a functional command, but no
matter how hard you try, you can't get the thing to work.

Another interesting problem: "foo" (the variable holding the next parsed
argument) will be set in the environment of *getopts* which will be lost
when getopts exits.  The shell will never see "foo" change.

So, the external getopts can't communicate the parsed options to the shell,
nor the option argument (OPTARG) or option index (OPTIND).  I'll bet the
external getopts doesn't even work for parsing beyond the first argument.
If it does work past the first argument (i.e. the first invocation of
getopts), then getopts is dropping temp file garbage somewhere.

Worse than useless :-)
