The license text of every such license can be found in LICENSES/. Some files are dual-licensed, e.g. "GPL-2.0-or-later OR MPL-1.1", which means you can choose one of these licenses. + +Libraries have their COPYING or LICENSE file in the respective subdirectory. + +See also https://spdx.org/licenses/ for the full license texts, and https://spdx.org/ids for the standardized header format. + + +License Compatibility +===================== + +Suggested reading for license version compatibility: https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility + +Roughly summarized (I am not a lawyer, this is not legal advice): +- You may legally make the following license changes without having to ask anyone: + LGPL-2.1-or-later -> GPL-2.0-or-later -> GPL-3.0-or-later + LGPL-3.0-or-later -> GPL-3.0-or-later +- Due to that, the resulting inkscape must be under GPL-3.0-or-later. +- Any license that is not "-or-later" is evil and must not be used in the inkscape project. + |
