At the very bottom of the docs in the troubleshooting section you will find the following line:

GetOptions does not return a false result when an option is not supplied

What you might want to try is to set a default variable to 0 that is changed to a 1 when any option is passed. (or vice versa), and then calling the usage sub appropriately.
