 * 
 * CMP - compound media player
 * 
 * is a client/server mediaplayer intended to play any media from any
 * workstation without the need to export or mount shares. cmps is an easy to
 * use backend with a (ready to use) HTML-interface. Additionally the backend
 * supports authentication via HTTP-digest authorization. cmpc is a client with
 * vdr-like osd-menues.
