33     *  Linking XviD statically or dynamically with other modules is making a

35     *  GNU General Public License cover the whole combination.

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