4
5 Notice
6
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:
10
11 * firstly, compliance with the principles governing the distribution
12 of Free Software: access to source code, broad rights granted to
13 users,
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.
18
19 The authors of the CeCILL (for Ce[a] C[nrs] I[nria] L[ogiciel] L[ibre])
20 license are:

36 Preamble
37
38 The purpose of this Free Software license agreement is to grant users
39 the right to modify and redistribute the software governed by this
40 license within the framework of an open source distribution model.
41
42 The exercising of these rights is conditional upon certain obligations
43 for users so as to preserve this status for all subsequent redistributions.
44
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.
49
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
56 suitability of the software as regards their requirements in conditions
57 enabling the security of their systems and/or data to be ensured and,
58 more generally, to use and operate it in the same conditions of
59 security. This Agreement may be freely reproduced and published,
60 provided it is not altered, and that no provisions are either added or
61 removed herefrom.
62
63 This Agreement may apply to any or all software for which the holder of
64 the economic rights decides to submit the use thereof to its provisions.

374
375
376 Article 9 - WARRANTY
377
378 9.1 The Licensee acknowledges that the scientific and technical
379 state-of-the-art when the Software was distributed did not enable all
380 possible uses to be tested and verified, nor for the presence of
381 possible defects to be detected. In this respect, the Licensee's

383 modifying and/or developing and reproducing the Software which are
384 reserved for experienced users.
385
386 The Licensee shall be responsible for verifying, by any or all means,
387 the suitability of the product for its requirements, its good working

389 or properties.
390
391 9.2 The Licensor hereby represents, in good faith, that it is entitled
392 to grant all the rights over the Software (including in particular the
393 rights set forth in Article 5).

395 9.3 The Licensee acknowledges that the Software is supplied "as is" by
396 the Licensor without any other express or tacit warranty, other than
397 that provided for in Article 9.2 and, in particular, without any warranty
398 as to its commercial value, its secured, safe, innovative or relevant
399 nature.
400
401 Specifically, the Licensor does not warrant that the Software is free
402 from any error, that it will operate without interruption, that it will
403 be compatible with the Licensee's own equipment and software
404 configuration, nor that it will meet the Licensee's requirements.
405
406 9.4 The Licensor does not either expressly or tacitly warrant that the
407 Software does not infringe any third party intellectual property right
408 relating to a patent, software or any other property right. Therefore,
409 the Licensor disclaims any and all liability towards the Licensee
410 arising out of any or all proceedings for infringement that may be
411 instituted in respect of the use, modification and redistribution of the
412 Software. Nevertheless, should such proceedings be instituted against
413 the Licensee, the Licensor shall provide it with technical and legal
414 assistance for its defense. Such technical and legal assistance shall be
415 decided on a case-by-case basis between the relevant Licensor and the
416 Licensee pursuant to a memorandum of understanding. The Licensor
417 disclaims any and all liability as regards the Licensee's use of the
418 name of the Software. No warranty is given as regards the existence of
419 prior rights over the name of the Software or as regards the existence
420 of a trademark.

430 10.2 A Licensee whose Agreement is terminated shall no longer be
431 authorized to use, modify or distribute the Software. However, any
432 licenses that it may have granted prior to termination of the Agreement
433 shall remain valid subject to their having been granted in compliance
434 with the terms and conditions hereof.

466 the necessary amendments so as to comply with said act or legislative
