Brilliant! ++ to the poster.
Although I would like to offer some very minimal constructive criticism. I'm a bit lazy at times, and depending on the complexity of the code I'm looking at, I'll either try to dissect it for my own edification, or just move on (I know shame on me, I'll never learn anything, etc, etc..). To make a long story short, I would have added a print statement in your show_form subroutine and added a line saying to submit a slash "/" to get a listing of all the POD docs on the system.
Grea code though, I know I'll make use of it.
