LICENSE

The CGAL software consists of several parts, each of which is
licensed under an open source license. It is also possible to obtain
commercial licenses from
GeometryFactory (www.geometryfactory.com)
for all or parts of CGAL.

The source code of the CGAL library can be found in the directories
"src" (excluding "src/Core") and "include/CGAL". It is specified in each
file of the CGAL library which license applies to it. This is either the
GNU Lesser General Public License (as published by the Free
Software Foundation; version 3 of the License) or the Q Public
License (version 1.0). The texts of both licenses can be found in the
files LICENSE.LGPL and LICENSE.QPL.  

Distributed along with CGAL (for the users' convenience), but not part
of CGAL, are the following third-party libraries, available under their
own licenses:

- CORE, in the directories "include/CORE" and "src/Core", is licensed
  under the QPL (see LICENSE.QPL).
- OpenNL, in the directory "include/OpenNL", is licensed under the
  GPL with additional exceptions (see LICENSE.OPENNL).

All other files that do not have an explicit copyright notice (e.g., all
examples and some demos) are licensed under a very permissive
license. The exact license text can be found in the file
LICENSE.FREE_USE. Note that some subdirectories have their own
copy of LICENSE.FREE_USE. These copies have the same license
text and differ only in the copyright holder.
