1. I typoed, and forgot a single quote after the h above, and an s at
the end of the function name. It should read:
getopts('h');
It should not read:
getopt('h);
2. You can do it all with a single getopts, like so:
our ($opt_h, $opt_d);
getopts('hd:');
That was copied directly out of a script I actually use from time to
time -- thus I'm positive that it works as written.
