* 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.
