  *  Linking XviD statically or dynamically with other modules is making a  
  *  combined work based on XviD.  Thus, the terms and conditions of the  
  *  GNU General Public License cover the whole combination.  
  *  
  *  As a special exception, the copyright holders of XviD give you  
  *  permission to link XviD with independent modules that communicate with  
  *  XviD solely through the VFW1.1 and DShow interfaces, regardless of the  
  *  license terms of these independent modules, and to copy and distribute  
  *  the resulting combined work under terms of your choice, provided that  
  *  every copy of the combined work is accompanied by a complete copy of  
  *  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  
  *  which is not derived from or based on XviD.  
  *  
  *  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.
