We change the license of our examples (stuff in [examples/](https://github.com/castle-engine/castle-engine/tree/master/examples) subdirectory) to be more permissive. Namely, all our example code and almost all our example data are now covered by the _modified BSD (3-clause)_ license. It’s a very permissive license that basically says _“we keep our copyright, but otherwise do what you want with these files, modify them as you like, and you don’t need to show your modifications to anyone”_.

This was always our intention, we want you to use the example code as a basis of your applications without any fuss.

More details, and precise legal words, are in our [licensing terms](https://github.com/castle-engine/castle-engine/blob/master/COPYING.md) and the [modified BSD (3-clause) license text is here](https://github.com/castle-engine/castle-engine/blob/master/doc/licenses/COPYING.BSD-3-clause.txt).
