+# Search and select windows similar to ido-mode for emacs
+#
+# INSTALL:
+#
+# This script requires that you have first installed and loaded 'uberprompt.pl'
+# Uberprompt can be downloaded from:
+#
+# http://github.com/shabble/irssi-scripts/raw/master/prompt_info/uberprompt.pl
+#
+# and follow the instructions at the top of that file for installation.
+#
+# USAGE:
+#
+# * Setup: /bind ^R /history_search_start
+#
+# * Then type ctrl-R and type what you're searching for
+#
+# * You can cycle through multiple matches with ^R (older matches), and
+# ^S (newer matches)
