The project was recently re-licenced under the Apache 2.0 licence, which is why you'll find it listed as GPL in distributions such as Debian. Now, the sources still include some autognu build files, which we do use during building. They are all GPL2+ or GPL3+. I wasn't sure whether they belonged in (license) as well.
