This script is intended for people who use the Guild Roster tool provided by http://www.wowroster.net , which takes data from the CharacterProfiler addon and displays it on a website.
The Guild Roster does have a guild bank feature, but it's not quite what I wanted so wrote my own interface instead. Looty supports multiple bank characters and has a flexible, searchable list of items showing the items currently in the bank along with, optionally, the overall bank balance.
