@PACKAGE@: xine-lib is the beating heart of xine (a free gpl-licensed 
@PACKAGE@: video player for unix-like systems) which among others provides 
@PACKAGE@: support for decoding (and playing back) of many today available
@PACKAGE@: audio/video codecs, like mpeg-4 (DivX), mpeg-2 (DVD, SVCD), 
@PACKAGE@: mpeg-1 (VCD), Quicktime and RealMedia just to name a few.
@PACKAGE@: This library contains (and uses) numerous processor specific 
@PACKAGE@: optimizations to provide a smooth playback and to minimize the 
@PACKAGE@: overall demand of CPU power.
