CeCILLGPL

CeCILLGPL, or CeCILL General Public License, is a free software license that is compatible with the GNU General Public License (GPL). It was created by the French government to promote the use of free software in public administration. The license is designed to be simple and easy to understand, while still providing strong copyleft protection for the software it covers.

CeCILLGPL is based on the GPL version 2, but with some modifications to address specific concerns of the French legal system. One of the key differences is the inclusion of a patent grant, which is not present in the original GPL. This patent grant ensures that contributors to the software do not assert patents against users of the software.

The license also includes a provision for the French government to use the software without complying with the terms of the license. This is intended to encourage the use of free software in public administration, while still providing strong protection for the software's authors.

CeCILLGPL is compatible with the GPL, meaning that software licensed under CeCILLGPL can be used in conjunction with software licensed under the GPL. This compatibility makes it a popular choice for developers who want to use free software in their projects, while still providing strong protection for their own work.

In summary, CeCILLGPL is a free software license that is compatible with the GPL, with some modifications to address specific concerns of the French legal system. It provides strong copyleft protection for the software it covers, and is compatible with the GPL, making it a popular choice for developers who want to use free software in their projects.
