* Linking XviD statically or dynamically with other modules is making a |
32 |

33 |
|
* GNU General Public License cover the whole combination. |

* As a special exception, the copyright holders of XviD give you |
36 |
|

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 |

44 |

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 |
|

50 |
|
* exception also makes it possible to release a modified version which |
51 |
|
* carries forward this exception. |
