Hmm, I've never used the module, but I took a look at it's documentation and it seems to contain more than adequate information.

You can find a copy at http://search.cpan.org/author/SMCCAM/X11-Protocol-0.04/Protocol.pm as well as various other places.

If you didn't know how to find the link I give above, I suggest reading this friendly guide to various perl documentation and resources.
