# mark channels to highlight on each message
#
# this script is useful with other scripts like:
# beep.pl, welauncher.pl, notify.py etc
#
# to mark channels on strartup set option "default_list" of this
# script ( via iset.pl plugin (/iset command) or /setp command)
#
# by default if message appeared on current channel ( and channel
# is marked) highlight event is not sended, to prevent this behaviour
# set "hl_on_cur_chan" option to 1
#
# Usage:
#   /mark
#   /smark
#   /unmark
#   /unmark all
#   /set plugins.var.tcl.chan_hl.default_list "#chan1,#chan2,#somechan"
#   /set plugins.var.tcl.chan_hl.hl_on_cur_chan 0

# TODO:
#   * separate channels with same name on different servers
