# Short-Description: uShare daemon providing a UPnP A/V & DLNA Media Server. 
# Description:       uShare is a UPnP (TM) A/V & DLNA Media Server. 
#	It implements the server component that provides UPnP 
#	media devices with information on available multimedia 
#	files. uShare uses the built-in http server of libupnp 
#	to stream the files to clients.
