+# This script will display an error message in the status-window if you try to
+# join a secure only channel without a secure connection. If you have the
+# setting autoclose_windows off, you will still get the old raw message in the
+# channel-window too.
+#
+# The script will die gracefully with a message if loaded in a version of
+# Irssi that already have the source-code fixed (ABI version 29 or higher).
+#
+# see https://github.com/irssi/irssi/pull/1196 for details about the code fix.
