 * 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.
