+mpdcontrol
+=======
+
+Description
+-----------
+Control Music Player Daemon via keybinds.
+
+By default `MODKEY + Escape` stops/pauses the current song or plays it depending
+on the state of the player.
+If the song is a file on disk it pauses it, if it's a stream it stops it since
+pause on a stream doesn't make sense.
+
+`MODKEY + F1` goes to previous song.
+`MODKEY + F2` goes to next song.
+
+`libmpdclient` is needed for this patch to work.
