36   *************************************************************************/   *  As a special exception, the copyright holders of XviD give you
37     *  permission to link XviD with independent modules that communicate with
38     *  XviD solely through the VFW1.1 and DShow interfaces, regardless of the
39     *  license terms of these independent modules, and to copy and distribute
40     *  the resulting combined work under terms of your choice, provided that
41     *  every copy of the combined work is accompanied by a complete copy of
42     *  the source code of XviD (the version of XviD used to produce the
43     *  combined work), being distributed under the terms of the GNU General
44     *  Public License plus this exception.  An independent module is a module
45     *  which is not derived from or based on XviD.
46     *
47     *  Note that people who make modified versions of XviD are not obligated
48     *  to grant this special exception for their modified versions; it is
49     *  their choice whether to do so.  The GNU General Public License gives
50     *  permission to release a modified version without this exception; this
51     *  exception also makes it possible to release a modified version which
52     *  carries forward this exception.
