+ * Project:   libfsScan: mediatypes and filesystem scanning
+ * 
+ * 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.
