- s²'s license and copyright
- ===========================
- (Before jumping to conclusions about legal stuff, read the *whole* section
- first.)
- s², including documentation, is licensed under the GNU General Public License
- (GPL), version 3 or later (at your choice). Because that is a free software
- license, it allows you study and run the code, make changes to your own version
- and distribute the updated code the others. This avoids legal vendor lock-in.
- There is one and only one exception to the s² is GPL-licensed rule:
- the GPL is embedded in the source code and documentation, as a work on itself,
- an appendix and attachment and is therefore not consider to be part of s²
- proper. It comes with its own license that doesn't allow modification, although
- verbatim copying and distribution is allowed.
- Keeping track
- -------------
- Which licenses apply is always indicated in the source code, with a comment
- of form `SPDX-License-Identifier: LICENSE OR OTHER-LICENSE`. The GPL,
- version 3 or later (at your choice) is abbreviated to `GPL-3.0-or-later`.
- Some parts may be dual-licensed under another license.
- To whom the copyright belongs is also always indicated, with a comment
- of form `Copyright (C) years author` or `Copyright © years author`.
- (A conversative stance on eligibility is taken: when in doubt, include
- the notice, and always be in doubt.)
- These two notices are required from contributors to the upstream project.
- As a fork, you can set your own conventions.
