## INSTRUCTIONS
###############################################################################
# This script will check the hosts of people joining channels against one or
# RBLs. Choose your RBLs wisely, some of them list DIALUP SPACE and that would
# be a bad thing to be matching your IRC users against
#
# Enable the 'proxycheck' flag for channels you want the script active on
# --> .chanset #somechannel +proxycheck
#
# Users who are +o, +v, or +f in your bot (local or global) won't be checked.
#
# Turn on console level d on the partyline to see some debug from the script
# --> .console +d (to enable)
# --> .console -d (to disable)
## CONFIG
