;; emms-gstreamer.el --- EMMS Gstreamer interaction
;; License : GPL v2.1 or later
;; currently outside other files, as it's very preliminary support
;; The wrapper concept is easier to set up than a generic gstreamer
;; support, but in the long term, it's probably not a good idea.
;; Installation instructions :
;; 1. Put (require 'emms-gstreamer) in your ~/.emacs or whatever you
;; use to configure EMMS.
;; 2. Put the wrappers in your `exec-path' :
;; (add-to-list 'exec-path "/path/to/wrappers") or the other way,
;; by moving them in an already present directory.
