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

36 |

|
* As a special exception, the copyright holders of XviD give you |
38 |
|

|
* XviD solely through the VFW1.1 and DShow interfaces, regardless of the |

50 |
|
* their choice whether to do so. The GNU General Public License gives |
51 |
