somescript -- A utility for ...
=head1 SYNOPSIS
B<somescript --help> for more information
somescript [options]
Options:
Note a few things.
- First, the short forms of the options are automatically available. You don't need to add them.
- Taking a reference to a variable when you declare it is a nice shorthand.
- I have pod2usage take __DATA__ as the input because I've had problems with this working when I do funky things with directories.
