+# This script is for if you have a split window for status (or anything else)
+# it makes it bigger when it's active.
+# (The way I have Irssi setup is with a split status window along the top,
+# created with /window show 1 in a channel window).
+ 
+# For example you do a command that outputs a large amount of text into
+# the status window such as /help or /motd (depending on what you put in
+# your status window). Then simply hit alt+up and the status window resizes
+# to give you more room to read the output, when you go back to another window
+# the status window will automatically go back to its previous size.
+
+# BUGS (mostly due to lack of Irssi API for split windows).
+# As far as I can see there is no easy way to find out where in a split a
+# window is displayed, so if more than one window is sticky inside a split
+# and you set that window in the setting below this script will have problems.
+# Also if you have more than 2 split windows things won't work as expected.
+
+# Setting: resize_windows
+# A space seperated list of windows that you want to be resized when you
+# change to them.
+# If it contains something that's not a (permanently displayed) split window
+# then windows will probably end up with incorrect sizes.
