“We classify a license according to certain key questions:
* Whether it qualifies as a free software license.
* Whether it is a copyleft license.
* Whether it is compatible with the GNU GPL. (This means you can combine a module which was released under that license with a GPL-covered module to
make one larger program.)
* Whether it causes any particular practical problems.
If you want help choosing a license, evaluating a license, or have any other questions about licenses, you can email us at
By the way, if you believe you have found a violation of one of our copyleft licenses, please refer to our license violation page.
