createUsernameIndex.pl - Cleans and indexes UseMod username database
UseModWiki has two problems with its user database (wikidb/user). First, it uses it as both a user database and also a session management database. As a result, the database becomes unnecessarily enormous with spurious "users" that do nothing but lock a user ID. Second, it does not keep a mapping of usernames to user IDs. As a result, users have to remember their user IDs in order to log in.
This script cleans up the user database and creates an index. You must run this script in order to convert UseModWiki or PurpleWiki (< 0.93) installations.
