Comment(by quozl):

 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
 [http://www.opensource.org/licenses/gpl-3.0.html 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 [http://www.opensource.org/licenses
 /bsd-license.php 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
 [http://www.opensource.org/licenses/zlib-license.php other copies]
