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.

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.

341 terms and conditions of such technical assistance, and/or such
|
|
342 maintenance, shall be set forth in a separate instrument. Only the

365 obligations, (ii) direct or consequential loss that is suffered by the
|
|
366 Licensee due to the use or performance of the Software, and (iii) more
|
|

|
|
369 loss of profits, operating loss, loss of customers or orders,
|
|
370 opportunity cost, any disturbance to business activities) or any or all
|
|
371 legal proceedings instituted against the Licensee by a third party,
|
|
372 shall constitute consequential loss and shall not provide entitlement to
|
|
373 any or all compensation from the Licensor.
|
|
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
|
|
382 attention has been drawn to the risks associated with loading, using,
|
|
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
|
|
388 order, and for ensuring that it shall not cause damage to either persons
|
|
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).
|
|
394
|
|
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
|
|
