21 :     *
22 :     * Under section 8 of the GNU General Public License, the copyright
23 :     * holders of XVID explicitly forbid distribution in the following
24 :     * countries:
25 :     *
26 :     * - Japan
27 :     * - United States of America
28 :     *
29 :     * Linking XviD statically or dynamically with other modules is making a
30 :     * combined work based on XviD. Thus, the terms and conditions of the
31 :     * GNU General Public License cover the whole combination.
32 :     *
33 :     * As a special exception, the copyright holders of XviD give you
34 :     * permission to link XviD with independent modules that communicate with
35 :     * XviD solely through the VFW1.1 and DShow interfaces, regardless of the
36 :     * license terms of these independent modules, and to copy and distribute
37 :     * the resulting combined work under terms of your choice, provided that
38 :     * every copy of the combined work is accompanied by a complete copy of
39 :     * the source code of XviD (the version of XviD used to produce the
40 :     * combined work), being distributed under the terms of the GNU General
41 :     * Public License plus this exception. An independent module is a module
42 :     * which is not derived from or based on XviD.
43 :     *
44 :     * Note that people who make modified versions of XviD are not obligated
45 :     * to grant this special exception for their modified versions; it is
46 :     * their choice whether to do so. The GNU General Public License gives
47 :     * permission to release a modified version without this exception; this
48 :     * exception also makes it possible to release a modified version which
49 :     * carries forward this exception.
