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'Energie Atomique - 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.

and technological establishment, having its principal place of business
at 3 rue Michel-Ange, 75794 Paris cedex 16, 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 these rights 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.

Article 7 - RELATED SERVICES

7.1 Under no circumstances shall the Agreement oblige the Licensor
to provide technical assistance or maintenance services for the Software.

However, the Licensor is entitled to offer this type of services.
The terms and conditions of such technical assistance, and/or such
maintenance, shall be set forth in a separate instrument. Only the
Licensor offering said maintenance and/or technical assistance services
shall incur liability therefor.

7.2 Similarly, any Licensor is entitled to offer to its licensees,
under its sole responsibility, a warranty, that shall only be binding
upon itself, for the redistribution of the Software and/or the

decide. Said warranty, and the financial terms and conditions of

between the Licensor and the Licensee.

Article 8 - LIABILITY

8.1 Subject to the provisions of Article 8.2, the Licensee shall be

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).

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 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 assistance for
its defense. Such technical and legal assistance 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.

Article 10 - TERMINATION

10.1 In the event of a breach by the Licensee of its obligations hereunder,
the Licensor may automatically terminate this Agreement 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.

Article 11 - MISCELLANEOUS

11.1 EXCUSABLE EVENTS

Neither Party shall be liable for any or all delay, or failure to perform

interruptions of the electricity or telecommunications networks, network
paralysis following a virus attack, intervention by government authorities,
natural disasters, water damage, earthquakes, fire, explosions, strikes
and labor unrest, war, 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.

are deemed authentic.

the Agreement, each with a separate number. These subsequent versions
may address new issues encountered by Free Software.

12.3 Any Software distributed under a given version of the Agreement may
only be subsequently distributed under the same version of the Agreement
or a subsequent version, subject to the provisions of Article 5.3.4.
