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
