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 CeCILL (for Ce[a] C[nrs] I[nria] L[ogiciel] L[ibre])
|
|
license are:

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.
|
|

However, the Licensor is entitled to offer this type of services. The

|
|
opportunity cost, any disturbance to business activities) or any or all
|
|
legal proceedings instituted against the Licensee by a third party,
|
|

|
|
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.
|
|
|
|
|
|

|
|
thirty (30) days after 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.
