  24 # NOTE: this controller is a SAMPLE, and thus doesn't implement all the D-Bus Media Player specification. http://wiki.videolan.org/index.php/DBus-spec
  25 # This is an unfinished document (on the 12/06/2006) and has been designed to be as general as possible.
  26 # So don't expect that much from this, but basic capabilities should work out of the box (Play/Pause/Next/Add)
  27 #
  28 # Also notice it has been designed first for a previous specificaiton, and thus some code may not work/be disabled
  29 #
  30 # You'll need pygtk >= 2.10 to use gtk.StatusIcon
