+#
+# Weechat script to display buffer actitity in tmux pane name.
+#
+# A workaround for: https://github.com/weechat/weechat/issues/741
+#
+# Ideally weechat should support multiple hotlists, to make it possible to
+# logically separate different chats into groups. Since such a feature is
+# missing, and implementing it would be non-trivial, this script helps if
+# running multiple weechat instances within a tmux. It abuses the ability to
+# rename pane to make them double as channel activity indicators.
+#
+# Requires something like: `F=~/.weechat/micmot-fifo; mkfifo $F; tail -f $F &`
+#
+# Also requires ":set-option allow-rename on" in the tmux buffer.
