I'm playing the game "Bookworm" found at Yahoo! Games, and I've decided I'd like to make a Perl application that, given the letter grid in the game, produces all the words that can be made, using a dictionary file for reference.

The letter grid looks like this: 

A J S B K
 F O X G
B K T C L
 G P Y H
C L U D M
 H Q Z I
D M V E N
 I R A J
E N W F O

(Update: correction made to available nodes here.) From the "U" you can move to the "P", "T", "Y", "Z", "V", or "Q". You can't use the same letter twice in one word. I'd like to know what modules monks would suggest I use. There are many graphing related modules, and I'm not sure where to start. I could make my own implementation, but it'd probably be faster to use an existing one.
