# This script shows modes in parts, quits, kicks, topic changes or actions, like show_nickmode does for public messages
#
# Usage:
# You must change your formats to include the $mode, for example:
# default format for part is:
#    {channick $0} {chanhost $1} has left {channel $2} {reason $3}
# to include the mode, do
#  /format part $mode{channick $0} {chanhost $1} has left {channel $2} {reason $3}
# for quits:
#  /format $mode{channick $0} {chanhost $1} has quit {reason $2}
