Physics is lacking a dedicated LICENSE file

[sdz]

Title says it all... ;)

Additional information gathered from dev.laptop.org ticket ​10011:

• a file containing the text of the GPLv3 should be included,

• all of the .py files need to have the copyright and license specified, not just the physics.py file.

A license and copyright analysis.

In summary, Physics contains multiple components of varying licenses; GPLv3, BSD, and zlib/libpng. Physics itself is licensed under GPLv3 but not in the safest manner. The dependencies in lib/ are correctly licensed, except for olpcgames which has a slight modification.

In detail, in the Physics mainline git repository:

• the file ​physics.py refers briefly to ​GPLv3 but not in the safest manner described by the license,
• there are two copyrights claimed for Physics and Elements in physics.py, the second is unnecessary as the Elements egg file in lib has copyright and license (GPLv3) properly identified,
• the file ​olpcgames/copying contains a modified ​BSD License, in that the contributors have been removed from the last paragraph that starts with THIS SOFTWARE IS PROVIDED, and the same file is provided by Maze with file name COPYING,
• the Box2D EGG-INFO says it is zlib/libpng License, the text of which can be found in init.py and matches ​other copies

Thanks, patches applied an new Physics-4 bundle uploaded to ASLO. Have a source tar-ball I can email someone if needed. I no longer have, or want, shell access to upload it to downloads.sl.org, but happy to upload to some other formal location if needed.
