+# disable hilighting of mass-hilights
+# (messages which contain a lot of nicknames)
+#
+# DESCRIPTION
+# sometimes a jester annoys a channel with a message
+# containing a lot of nicks that are in that channel.
+# this script prevents hilighting of a window in this
+# case. number of nicks in the message is user
+# configurable in the variable mass_highlight_threshold.
+#
+# CHANGELOG
+# * 01.05.2004
+# fixed problems with nicks containing brackets
+# added comments, description and this changelog :)
+# * 30.05.2004
+# first version of the script
+# * 21.08.2010
+# modified it a lot to work with pubmessages so it has access to
+# the sender and channel more easily. Also added configurable actions
+# to take when flooding is detected.

+
+Usage:
+
+use /set mass_hilight_threshold to set how many matching nicks from the current
+ are required to trigger the hilight flood detection.
+
+use /set mass_hilight_action to configure what happens when they do.  You can specify
+multiple actions, separated by ; (semicolons)
+
+Two special actions exist: 'suppress', which prevents the message from being
+displayed to you at all, and 'kick', which expands to the action '/kick #channel
+$nick'.
+
+Any other actions you wish to take are processed as regular Irssi commands, but
+the following variables are replaced:
+
+$nick - becomes the nick of the person who triggered this script
+$chan - the channel in which it happened
+$host - the hostmask of the offender
+
+For example:
+
+/set mass_hilight_action /echo hilight flooding by: $nick ; /kickban $chan $nick "Hilight flooding is not permitted here."
