  *  As a special exception, the copyright holders of XviD give you

  *  the source code of XviD (the version of XviD used to produce the  
  *  combined work), being distributed under the terms of the GNU General  
  *  Public License plus this exception.  An independent module is a module

  *  Note that people who make modified versions of XviD are not obligated  
  *  to grant this special exception for their modified versions; it is  
  *  their choice whether to do so.  The GNU General Public License gives  
  *  permission to release a modified version without this exception; this  
  *  exception also makes it possible to release a modified version which  
  *  carries forward this exception.
