+
+# Usage
+# =====
+# Use this script to hide and re-add lines into your Irssi view. You
+# can grab a custom-modified recentdepart.pl to hide smart-filtered
+# messages instead of ignore, if you do
+#
+# /set recdep_use_hideshow ON
+#
+# You can use trigger.pl with:
+#
+# /trigger add ... -command 'script exec $$Irssi::scripts::hideshow::hide_next = 1'
+#
+# instead of -stop
+
+# Options
+# =======
+# /set hideshow_level <levels>
+# * list of levels that should be hidden from view
+#
+# /set hideshow_hide <ON|OFF>
+# * if hiding is currently enabled or not. make a key binding to
+# conveniently toggle this setting (see below)
+
+# Commands
+# ========
+# you can use this key binding:
+#
+# /bind meta-= command ^toggle hideshow_hide
+#
+# /scrollback status hidden
+# * like /scrollback status, but for the hidden part (some statistics)
