40     *  license terms of these independent modules, and to copy and distribute

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
