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

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.
