# svnwatch - a subversion plugin for rbot.
# author(s): Robby Russell and Ben Bleything of the PDX.rb
# 
# This file should be placed in the rbot plugins/ directroy. When you load rbot
# it will scan the directory and load this plugin. DRb will automatically start up.

  :chan => '#pdx.rb'     # IRC channel that you want rbot to send notices to
