- * File: AbstractMedia.cc
- * Created: 2. Juli 2012, 14
- * Author: <a href="mailto:geronimo013@gmx.de">Geronimo</a>
- * 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.
