 Contributor License Agreement

  By submitting code to the github project, you agree to the following:

  (1) you expressly guarantee that you are the sole author of all
  parts of the contribution.

  (2) you expressly permit the author, Auke Kok, of entity_ai to
  relicense all (your) contributions to LGPL-2.1+ (for code) and
  CC-BY-SA-4.0 (for all artwork) FOR THE SOLE PURPOSE OF MERGING THIS
  CODE INTO MINETEST_GAME[1] SHOULD THIS MERGE OCCUR AND BE ACCEPTED.

[1] https://github.com/minetest/minetest_game

This CLA is present here to (1) make sure this code doesn't fragment and (2) is distributed in a compatible way in the future in minetest_game should this be wanted or preferred. This gives maximum reassurance that contributions to this project are going to be used in the best interest of the minetest_game, and that people who make valuable changes to this project are required to give changes back until such a merge happens. If the merge occurs in the future, all contributions will become available under a permissive license to everyone, encouraging everyone to help with making this code mergable.

NOTICE FOR MONSTER ADDITIONS *

The license for any monster using the exported API has to be compatible with the license of the API itself. That means that any custom monster code has to be AGPL-3.0 until it gets merged in minetest_game[1], after which it has to be LGPL-2.1+ or compatible with that. You may choose to license your artwork in any way you see fit, however.

SPLITTING UP THIS PROJECT *

In the future, the core API code will be seperated from the monster definitions. Each monster will be it's own mod permitting users to disable/enable monsters as they see fit. This organization will help to keep per-mod specific code out of the core and make core functions better suited to handle all monsters.
