| 31 : | * Linking XviD statically or dynamically with other modules is making a | ||

| 35 : | * As a special exception, the copyright holders of XviD give you | ||
| 36 : | * permission to link XviD with independent modules that communicate with | ||
| 37 : | * XviD solely through the VFW1.1 and DShow interfaces, regardless of the | ||
| 38 : | * license terms of these independent modules, and to copy and distribute | ||
| 39 : | * the resulting combined work under terms of your choice, provided that | ||
| 40 : | * every copy of the combined work is accompanied by a complete copy of | ||
| 41 : | * the source code of XviD (the version of XviD used to produce the | ||
| 42 : | * combined work), being distributed under the terms of the GNU General | ||
| 43 : | * Public License plus this exception. An independent module is a module | ||
| 44 : | * which is not derived from or based on XviD. | ||
| 45 : | * | ||
| 46 : | * Note that people who make modified versions of XviD are not obligated | ||
| 47 : | * to grant this special exception for their modified versions; it is | ||
| 48 : | * their choice whether to do so. The GNU General Public License gives | ||
| 49 : | * permission to release a modified version without this exception; this | ||
| 50 : | * exception also makes it possible to release a modified version which | ||
| 51 : | * carries forward this exception. | ||
