Closes #60.

Summary

The repository had two licence files that disagreed: LICENSE (MIT) and COPYING (GNU GPL v3). The project goes with MIT, so this PR:

  • removes COPYING;
  • removes the prebuilt vata executable at the repository root (added in 47e640e). Nothing in the build, the tests or the scripts uses it. The only mention of VATA, in unit_tests/reference_answers/artifact_evaluation.sh, points to an external libvata build. The binary also came with no source or licence information;
  • adds a short License section to the README that points to LICENSE.

LICENSE is unchanged.

Older source files

Some source files carry their original copyright lines with no licence named:

  • 8 files say "Copyright (c) 2011 Jiri Simacek", for example include/autoq/simulation/binary_relation.hh and the other simulation headers;
  • 15 files say "Copyright (c) 2011 Ondra Lengal" (one says 2015), for example include/autoq/autoq.hh and include/autoq/aut_description.hh.

Both authors agree to these files being distributed under MIT, so they need no change here. A later PR could add an SPDX-License-Identifier: MIT line to the source headers.

Also for the maintainers to decide: LICENSE names only "Copyright (c) 2023 Wei-Lun Tsai". You may want it to name all AutoQ authors, or "the AutoQ authors".

The repository shipped two conflicting licence files: LICENSE (MIT) and
COPYING (GNU GPL v3). Keep MIT:

- Remove COPYING.
- Remove the prebuilt `vata` executable from the repository root. Nothing
  in the build, tests or scripts uses it, and it came with no source or
  licence information.
- Add a License section to the README.
