This Agreement is a free software license that is the result of discussions between its authors in order to ensure compliance with the two main principles guiding its drafting:
The following bodies are the authors of the license CeCILL1:
Commissariat à l’Energie Atomique – CEA, a public scientific, technical and industrial establishment, having its principal place of business at 31-33 rue de la Fédération, 75752 PARIS cedex 15.
Centre National de la Recherche Scientifique – CNRS, a public scientific and technological establishment, having its principal place of business at 3 rue Michel-Ange 75794 Paris cedex 16.
Institut National de Recherche en Informatique et en Automatique– INRIA, a public scientific and technological establishment, having its principal place of business at Domaine de Voluceau, Rocquencourt, BP 105, 78153 Le Chesnay cedex.
The purpose of this Free Software Licensing Agreement is to grant users the right to modify and redistribute the software governed by this license within the framework of an “open source” distribution model.
The exercising of these rights is conditional upon certain obligations for users so as to ensure that this status is retained for subsequent redistribution operations.
Nevertheless, access to the source code, and the resulting rights to copy, modify and redistribute only provide users with a limited warranty and the software’s author, the holder of the economic rights, and the successive licensors only have limited liability.
In this respect, the user’s attention is drawn to the risks associated with loading, using, modifying and/or developing or reproducing the software by the user in light of its specific status of free software, that may mean that it is complicated to manipulate, and that also therefore means that it is reserved for developers and experienced professionals having in-depth IT knowledge. Users are therefore encouraged to load and test the Software’s suitability as regards their requirements in conditions enabling the security of their systems and/or data to be ensured and, more generally, to use and operate it in the same conditions as regards security. This Agreement may be freely reproduced and published, provided it is not altered, and that no Articles are either added or removed herefrom.
This Agreement may apply to any or all software for which the holder of the economic rights decides to submit the operation thereof to its provisions.
For the purposes of this Agreement, when the following expressions commence with a capital letter, they shall have the following meaning:
Agreement: means this Licensing Agreement, and any or all of its subsequent versions.
Software: means the software in its Object Code and/or Source Code form and, where applicable, its documentation, “as is” at the time when the Licensee accepts the Agreement.
Initial Software: means the Software in its Source Code and/or Object Code form and, where applicable, its documentation, “as is” at the time when it is distributed for the first time under the terms and conditions of the Agreement.
Modified Software: means the Software modified by at least one Contribution.
Source Code: means all the Software’s instructions and program lines to which access is required so as to modify the Software.
Object Code: means the binary files originating from the compilation of the Source Code.
Holder: means the holder of the economic copyright over the Initial Software.
Licensee(s): mean(s) the Software user(s) having accepted the Agreement.
Contributor: means a Licensee having made at least one Contribution.
Licensor: means the Holder, or any or all other individual or legal entity, that distributes the Software under the Agreement.
Contributions: mean any or all modifications, corrections, translations, adaptations and/or new functionalities integrated into the Software by any or all Contributor, and the Static Modules.
Module: means a set of sources files including their documentation that, once compiled in executable form, enables supplementary functionalities or services to be developed in addition to those offered by the Software.
Dynamic Module: means any or all module, created by the Contributor, that is independent of the Software, so that this module and the Software are in two different executable forms that are run in separate address spaces, with one calling the other when they are run.
Static Module: means any or all module, created by the Contributor and connected to the Software by a static link that makes their object codes interdependent. This module and the Software to which it is connected, are combined in a single executable.
Parties: mean both the Licensee and the Licensor.
These expressions may be used both in singular and plural form.
The purpose of the Agreement is to enable the Licensor to grant the Licensee, non-exclusive, transferable and worldwide License for the Software as set forth in Article 5 hereinafter for the whole term of protection of the rights over said Software.
