CeCILL FREE SOFTWARE LICENSE AGREEMENT
|
||||
|
||||
Version 2.1 dated 2013-06-21 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'énergie atomique et aux énergies alternatives - 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 The purpose of this Free Software license 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 this right is conditional upon certain obligations for users
|
||||
so as to preserve this status for all subsequent redistributions.
|
||||
|
||||
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.

||||

|
||||
Agreement and shall not be incurred as a result of in particular: (i) loss
|
||||
due the Licensee's total or partial failure to fulfill its obligations, (ii)

or business loss (i.e. loss of data, loss of profits, operating loss, loss
|
||||
of customers or orders, opportunity cost, any disturbance to business activities)
|
||||
or any or all legal proceedings instituted against the Licensee by a third
|
||||
party, shall constitute consequential loss and shall not provide entitlement
|
||||
to any or all compensation from the Licensor.
|
||||
|
||||
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 <#scope> ).
|
||||
|
||||
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 <#good-faith> 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 expertise for its defense. Such technical and legal expertise 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.
|
||||
|
||||

notice has been sent to the Licensee and has remained ineffective.
|
||||
|
||||
10.2 A Licensee whose Agreement is terminated shall no longer be authorized
|
||||
to use, modify or distribute the Software. However, any licenses that it may
|
||||
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.

||||
|
||||

etc.
|
||||
|
||||
11.2 Any failure by either Party, on one or more occasions, to invoke one
|
||||
or more of the provisions hereof, shall under no circumstances be interpreted
|
||||
as being a waiver by the interested Party of its right to invoke said provision(s)
|
||||
subsequently.
|
||||
|
||||
11.3 The Agreement cancels and replaces any or all previous agreements, whether
|
||||
written or oral, between the Parties and having the same purpose, and constitutes
|
||||
the entirety of the agreement between said Parties concerning said purpose.

||||
No supplement or modification to the terms and conditions hereof shall be
|
||||
effective as between the Parties unless it is made in writing and signed by
|
||||
their duly authorized representatives.
|
||||
|
||||
11.4 In the event that one or more of the provisions hereof were to conflict
|
||||
with a current or future applicable act or legislative text, said act or legislative
|
||||
text shall prevail, and the Parties shall make the necessary amendments so
|
||||
as to comply with said act or legislative text. All other provisions shall
|
||||
remain effective. Similarly, invalidity of a provision of the Agreement, for

||||
any reason whatsoever, shall not cause the Agreement as a whole to be invalid.
