You could convert those comments into POD and get a manpage for free with perldoc: 
=head1

Usage: rename-script [OPTIONS] PATH

Options:

  -p   Pattern to look for in file's name. Default '\s'
  -r   Replacement string. Default '_'
  -n   Don't use 'g' option modifier with pattern matching

=cut

[download]
Then at your command prompt... 
$ perldoc rename-script

[download]
You could get even fancier with Pod::Usage.
