2 CeCILL-C FREE SOFTWARE LICENSE AGREEMENT
7 This Agreement is a Free Software license agreement that is the result
8 of discussions between its authors in order to ensure compliance with
9 the two main principles guiding its drafting:
11 * firstly, compliance with the principles governing the distribution
12 of Free Software: access to source code, broad rights granted to
14 * secondly, the election of a governing law, French law, with which
15 it is conformant, both as regards the law of torts and
16 intellectual property law, and the protection that it offers to
17 both authors and holders of the economic rights over software.
19 The authors of the CeCILL-C (for Ce[a] C[nrs] I[nria] L[logiciel] L[ibre])
22 Commissariat à l'Energie Atomique - CEA, a public scientific, technical
23 and industrial research establishment, having its principal place of
24 business at 25 rue Leblanc, immeuble Le Ponant D, 75015 Paris, France.
26 Centre National de la Recherche Scientifique - CNRS, a public scientific
27 and technological establishment, having its principal place of business
28 at 3 rue Michel-Ange, 75794 Paris cedex 16, France.
30 Institut National de Recherche en Informatique et en Automatique -
31 INRIA, a public scientific and technological establishment, having its
32 principal place of business at Domaine de Voluceau, Rocquencourt, BP

38 The purpose of this Free Software license agreement is to grant users the
39 right to modify and re-use the software governed by this license.
41 The exercising of this right is conditional on the obligation to make
42 available to the community the modifications made to the source code of the
43 software so as to contribute to its evolution.
45 In consideration of access to the source code and the rights to copy,
46 modify and redistribute granted by the license, users are provided only
47 with a limited warranty and the software's author, the holder of the
48 economic rights, and the successive licensors only have limited liability.
50 In this respect, the risks associated with loading, using, modifying
51 and/or developing or reproducing the software by the user are brought to
52 the user's attention, given its Free Software status, which may make it
53 complicated to use, with the result that its use is reserved for
54 developers and experienced professionals having in-depth computer
55 knowledge. Users are therefore encouraged to load and test the suitability
56 of the software as regards their requirements in conditions enabling the
57 security of their systems and/or data to be ensured and, more generally, to
58 use and operate it in the same conditions of security. This Agreement may be
59 freely reproduced and published, provided it is not altered, and that no
60 provisions are either added or removed herefrom.
62 This Agreement may apply to any or all software for which the holder of
63 the economic rights decides to submit the use thereof to its provisions.

375 any or all compensation from the Licensor.
380 9.1 The Licensee acknowledges that the scientific and technical
381 state-of-the-art when the Software was distributed did not enable all
382 possible uses to be tested and verified, nor for the presence of
383 possible defects to be detected. In this respect, the Licensee's
384 attention has been drawn to the risks associated with loading, using,
385 modifying and/or developing and reproducing the Software which are
386 reserved for experienced users.

389 the suitability of the product for its requirements, its good working order,
390 and for ensuring that it shall not cause damage to either persons or
393 9.2 The Licensor hereby represents, in good faith, that it is entitled
394 to grant all the rights over the Software (including in particular the
395 rights set forth in Article 5).

398 the Licensor without any other express or tacit warranty, other than
399 that provided for in Article 9.2 and, in particular, without any warranty
400 as to its commercial value, its secured, safe, innovative or relevant
403 Specifically, the Licensor does not warrant that the Software is free
404 from any error, that it will operate without interruption, that it will
405 be compatible with the Licensee's own equipment and software
406 configuration, nor that it will meet the Licensee's requirements.
408 9.4 The Licensor does not either expressly or tacitly warrant that the
409 Software does not infringe any third party intellectual property right
410 relating to a patent, software or any other property right. Therefore,
411 the Licensor disclaims any and all liability towards the Licensee
412 arising out of any or all proceedings for infringement that may be
413 instituted in respect of the use, modification and redistribution of the
414 Software. Nevertheless, should such proceedings be instituted against
415 the Licensee, the Licensor shall provide it with technical and legal
416 assistance for its defense. Such technical and legal assistance shall be
417 decided on a case-by-case basis between the relevant Licensor and the
418 Licensee pursuant to a memorandum of understanding. The Licensor
419 disclaims any and all liability as regards the Licensee's use of the
420 name of the Software. No warranty is given as regards the existence of

449 government authorities, natural disasters, water damage, earthquakes,
450 fire, explosions, strikes and labor unrest, war, etc.
452 11.2 Any failure by either Party, on one or more occasions, to invoke
453 one or more of the provisions hereof, shall under no circumstances be
