The main library is distributed under [LGPL v2.1](https://www.gnu.org/licenses/lgpl-2.1.html) or later. But it
relies on [MAGE](https://github.com/numediart/mage) for better responsiveness. MAGE is distributed under
[GPL v3](https://www.gnu.org/licenses/gpl-3.0.html) or later, so the combination is under GPL v3 or later. If you
want to use the library in your program under [GPL v2](https://www.gnu.org/licenses/gpl-2.0.html) or LGPL, compile the library without MAGE.
