CeCILL-B FREE SOFTWARE LICENSE AGREEMENT Notice |
|
|
|
This Agreement is a Free Software license agreement that is the result of |
|
discussions between its authors in order to ensure compliance with the two |
|
main principles guiding its drafting: |
|
|
|
* firstly, compliance with the principles governing the distribution of Free |
|
Software: access to source code, broad rights granted to users, |
|
|
|
* secondly, the election of a governing law, French law, with which it is |
|
conformant, both as regards the law of torts and intellectual property law, |
|
and the protection that it offers to both authors and holders of the economic |
|
rights over software. |
|
|
|
The authors of the CeCILL¹ license are: |
|
|
|
|
|
|
|
Commissariat à l'Energie Atomique - CEA, a public scientific, technical and |
|
industrial research establishment, having its principal place of business |
|
at 25 rue Leblanc, immeuble Le Ponant D, 75015 Paris, France. |
|
|
|
|
|
|
|
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, France. |
|
|
|
|
|
|
|
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, France. |
|
|
|
Preamble This Agreement is an open source software license intended to give |
|
users significant freedom to modify and redistribute the software licensed |
|
hereunder. |
|
|
|
The exercising of this freedom is conditional upon a strong obligation of |
|
giving credits for everybody that distributes a software incorporating a software |
|
ruled by the current license so as all contributions to be properly identified |
|
and acknowledged. |
|
|
|
In consideration of access to the source code and the rights to copy, modify |
|
and redistribute granted by the license, users are provided only 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 risks associated with loading, using, modifying and/or |
|
developing or reproducing the software by the user are brought to the user's |
|
attention, given its Free Software status, which may make it complicated to |
|
use, with the result that its use is reserved for developers and experienced |
|
professionals having in-depth computer knowledge. Users are therefore encouraged |
|
to load and test the suitability of the software 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 of security. |
|
This Agreement may be freely reproduced and published, provided it is not |
|
altered, and that no provisions 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 use thereof to its provisions. |
|
|

|
|
|
Article 9 - WARRANTY |
|
|
|
9.1 The Licensee acknowledges that the scientific and technical state-of-the-art |
|
when the Software was distributed did not enable all possible uses to be tested |
|
and verified, nor for the presence of possible defects to be detected. In |
|
this respect, the Licensee's attention has been drawn to the risks associated |
|
with loading, using, modifying and/or developing and reproducing the Software |
|
which are reserved for experienced users. |
|
|
|
The Licensee shall be responsible for verifying, by any or all means, the |
|
suitability of the product for its requirements, its good working order, and |
|
for ensuring that it shall not cause damage to either persons or properties. |
|
|
|
9.2 The Licensor hereby represents, in good faith, that it is entitled to |
|
grant all the rights over the Software (including in particular the rights |
|
set forth in Article 5). |

9.3 The Licensee acknowledges that the Software is supplied "as is" by the |
|
Licensor without any other express or tacit warranty, other than that provided |
|
for in Article 9.2 and, in particular, without any warranty as to its commercial |
|
value, its secured, safe, innovative or relevant nature. |
|
|
|
Specifically, the Licensor does not warrant that the Software is free from |
|
any error, that it will operate without interruption, that it will be compatible |
|
with the Licensee's own equipment and software configuration, nor that it |
|
will meet the Licensee's requirements. |
|
|
|
9.4 The Licensor does not either expressly or tacitly warrant that the Software |
|
does not infringe any third party intellectual property right relating to |
|
a patent, software or any other property right. Therefore, the Licensor disclaims |
|
any and all liability towards the Licensee arising out of any or all proceedings |
|
for infringement that may be instituted in respect of the use, modification |
|
and redistribution of the Software. Nevertheless, should such proceedings |
|
be instituted against the Licensee, the Licensor shall provide it with technical |
|
and legal assistance for its defense. Such technical and legal assistance |
|
shall be decided on a case-by-case basis between the relevant Licensor and |
|
the Licensee pursuant to a memorandum of understanding. The Licensor disclaims |
|
any and all liability as regards the Licensee's use of the name of the Software. |
|
No warranty is given as regards the existence of prior rights over the name |
|
of the Software or as regards the existence of a trademark. |

|
10.2 A Licensee whose Agreement is terminated shall no longer be authorized |

|
have granted prior to termination of the Agreement shall remain valid subject |
|
to their having been granted in compliance with the terms and conditions hereof. |
