I would recommend using another module. This module is not under active development, and the interface is a bit weird. I wrote this module to experience writing a module and I thought at the time it performed a unique service unavailable elsewhere on CPAN. As the search engines have improved, I have found this to not be the case, and there are other modules which offer more functionality than this one. That said, if you use the module as it was intended, it will reliably work for you. Good luck.
