+;; This file provides an interface to retrieving comments from
+;; ogg-files, using Lawrence Mitchells ogg-comment.el.
+
+;; To activate, put something like this in your ~/.emacs:
+
+;; (require 'emms-info-ogg)
+;; (add-to-list 'emms-info-methods-list 'emms-info-ogg-comment)
+
+;; You'll of course need to also have a player if you want to actually
