# COIBot - a Conflict Of Interest recognition bot for mediawiki projects.
# Written by Dirk Beetstra, 2007.
#
# COIBot reads link-addition feeds from IRC (e.g. #wikipedia-en-spam), && isolates the username, pagename && links added.
# It then compares the username with the pagename && the links added; a too big an overlap gets reported.

#First, let's declare our modules.
