 ; *  
 ; *  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.
