+#########
+# USAGE
+###
+#
+# copy the script to ~/.irssi/scripts/
+#
+# In irssi:
+#
+# /script load chanact
+# /statusbar window add -after act chanact
+#
+# If you want the item to appear on another position read the help
+# for /statusbar.
+# To remove the [Act: 1,2,3] item type:
+#
+# /statusbar window remove act
+#
+# To see all chanact options type:
+#
+# / set chanact_
+#
+# After these steps you have your new statusbar item and you can start giving
+# aliases to your windows. Go to the window you want to give the alias to
+# and say:
+#
+# /window_alias <alias char>
+#
+# You can also remove the aliases with:
+#
+# /window_unalias <alias char>
+#
+# or in aliased window:
+#
+# /window_unalias
+#
+# To see a list of your windows use:
+#
+# /window list
+#
+#########
+# OPTIONS
+#########
+#
+# /set chanact_chop_status <ON|OFF>
+# * ON : shorten (Status) to S
+# * OFF : don't do it
+#
+# /set chanact_show_mode <ON|OFF>
+# * ON : show channel modes
+# * OFF : don't show channel modes
+#
+# /set chanact_sort_by_activity <ON|OFF>
+# * ON : sorts the list by last activity
+# * OFF : sorts the list by window number
+#
+# /set chanact_display <string>
+# * string : Format String for one Channel. The following $'s are expanded:
+# $C : Channel
+# $N : Number of the Window
+# $M : Mode in that channel
+# $H : Start highlightning
+# $S : Stop highlightning
+# * example:
+#
+# /set chanact_display $H$N:$M.$S$C
+#
+# will give you on #irssi.de if you have voice
+#
+# [3:+.#irssi.de]
+#
+# with '3:+.' highlighted and the channel name printed in regular color
+#
+# /set chanact_display_alias <string>
+# as 'chanact_display' but is used if the window has an alias and
+# 'chanact_show_alias' is set to on.
+#
+# /set chanact_show_names <ON|OFF>
+# * ON : show the channelnames after the number/alias
+# * OFF : don't show the names
+#
+# /set chanact_abbreviate_names <int>
+# * 0 : don't abbreviate
+# * <int> : strip channel name prefix character and leave only
+# that many characters of the proper name
+#
+# /set chanact_show_alias <ON|OFF>
+# * ON : show the aliase instead of the refnum
+# * OFF : shot the refnum
+#
+# /set chanact_header <str>
+# * <str> : Characters to be displayed at the start of the item.
+# Defaults to: "Act: "
+#
+# /set chanact_separator <str>
+# * <str> : Charater to use between the channel entries
+#
+# /set chanact_autorenumber <ON|OFF>
+# * ON : Move the window automatically to first available slot
+# starting from "chanact_renumber_start" when assigning
+# an alias to window. Also moves the window back to a
+# first available slot from refnum 1 when the window
+# loses it's alias.
+# * OFF : Don't move the windows automatically
+#
+# /set chanact_renumber_start <int>
+# * <int> : Move the window to first available slot after this
+# num when "chanact_autorenumber" is ON.
+#
+# /set chanact_remove_hash <ON|OFF>
+# * ON : Remove &#+!= from channel names
+# * OFF : Don't touch channel names
+#
+# /set chanact_remove_prefix <string>
+# * <string> : Regular expression used to remove from the
+# beginning of the channel name.
+# * example :
+# To shorten a lot of debian channels:
+#
+# /set chanact_remove_prefix deb(ian.(devel-)?)?
+#
+# /set chanact_filter <int>
+# * 0 : show all channels
+# * 1 : hide channels without activity
+# * 2 : hide channels with only join/part/etc messages
+# * 3 : hide channels with text messages
+# * 4 : hide all channels (now why would you want to do that)
+#

+# HINTS
+#########
+#
+# If you have trouble with wrong colored entries your 'default.theme' might
+# be too old. Try on a shell:
+#
+# $ mv ~/.irssi/default.theme /tmp/
+#
+# And in irssi:
+# /reload
+# /save
