+;; Domgoergen (kanaldrache@gmx.de) and Jorgen Schäfer
+;; <forcer@forcix.cx>
+
+;; To activate this method for getting info, use something like:
+
+;; (require 'emms-info-libtag)
+;; (add-to-list 'emms-info-functions 'emms-info-libtag)
+
+;; Note that you should remove emms-info-mp3info and emms-info-ogginfo
+;; from the emms-info-functions list if you want to avoid
+;; conflicts. For example, to set libtag as your exclusive info
+;; provider:
+
+;; (setq emms-info-functions '(emms-info-libtag))
+
