License FAQ
From Yage3D Wiki
Yage is distributed under the terms of the LGPL version 3. What does this mean? In simplified terms, if you have a program that uses Yage, you can distribute that program under any license you prefer, so long as you make it clear that Yage is being used and that Yage is distributed under the terms of the LGPL v3. If you modify Yage itself, those changes must be released under the LGPL v3. These are the basics. Read the complete license if you want to know every detail.
Perhaps some examples will help:
| Use Case | Requirements |
|---|---|
| I'm making a (free, commercial, open, or closed-source) game or other program that uses Yage and I plan to give/sell it to other people. |
|
| I'm modifying or adding to Yage itself to make a new game engine. |
|
If you have any questions, would like to see another use case added, or consider this interpretation of the LGPL v3. to be incorrect, please notify us.
