    Partly based upon E-Leds 0.2 by Mathias Meisfjordskar 
    <mathiasm@ifi.uio.no> and the graphics are taken from it too. 

    * v0.6 prepared for gai 0.6.0
    * v0.5 Updates for gai 0.5.0 - Changes automagically.
    * v0.4 port to gai 0.5.0pre
    * v0.3 includes rotation. Usefull in dockapp mode if you have your
      panel vertical. Gnome takes care of it otherwise.
      The graphic has also some changes.
