*
* 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.
