# Based on compact.pl by Wouter Coekaerts <wouter@coekaerts.be>
# http://wouter.coekaerts.be/irssi/scripts/compact.pl.html
# Usage
# =====
# Once loaded, the script will summarise and remove any
# JOINS/PARTS/QUITS/NICKS
# Options
# =======
# /set revolve_show_nickchain <ON|OFF>
# * whether more than two nick names should be shown when people
# change nicks
#
# /set revolve_modes <ON|OFF>
# * whether MODES should also be summarised
#
# /set revolve_show_rejoins <ON|OFF>
# * whether rejoins should be displayed instead of clearing them out
# from QUITS/PARTS silently
#
# /set revolve_show_time <ON|OFF>
# * whether timestamp should be displayed before and after the summary
# line
#
# To change the look and feel, edit the script source code below:
# -----8<------ do not change this part ----->8-----
