[development] Extending Modules

[Rob Barreca]

A great place to start learning about piggybacking on other modules is 
the hook_nodeapi and hook_form_alter hooks.  Those should allow you to 
do most of what you want.

But if the functionality belongs in the module, submit a patch and help 
that module become better.

Good luck,
