; Revision history: |
; * Linking XviD statically or dynamically with other modules is making a |
32 |
; |
; * combined work based on XviD. Thus, the terms and conditions of the |
33 |
; 24.11.2001 initial version (Isibaar) |
; * GNU General Public License cover the whole combination. |
34 |
; 23.07.2002 thread safe (edgomez) |
; * |
35 |
; |
; * As a special exception, the copyright holders of XviD give you |
36 |
; $Id$ |
; * 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. |
