We change the license of our examples (stuff in 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 and the modified BSD (3-clause) license text is here.
