-;;; Commentary:
-;;
-;; Set `emms-stream-info-backend' to either 'vlc or 'mplayer, which
-;; are the two currently supported backends for retrieving stream
-;; information.  You can then either call `emms-stream-info-message'
-;; directly or hit "i" in the `emms-streams' buffer over stream you
-;; want to investigate.
-;;
-;; Note that you do not have to be playing the stream in question in
-;; order to find out what is playing on it since this library will
-;; open its own connection to the streaming server.
-;;
-;; Please send bug reports and stations which do not work to the
-;; maintainer (email at the top of this file).
-
-;;; History:
-;; 
-;; This library was re-implemented from scratch around January of
-;; 2009. If you are looking for the old code then grab source code
-;; older than that.
