 ; *  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
