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.

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 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.

all measures required to ensure respect of said intellectual property 
rights of the Holder and/or Contributors.

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 
Modified Software, under terms and conditions that it is free to 
decide. Said warranty, and the financial terms and conditions of 
its application, shall be subject of a separate instrument executed 
between the Licensor and the Licensee.

Article 8 - LIABILITY

8.1 Subject to the provisions of Article 8.2, the Licensee shall be 
entitled to claim compensation for any direct loss it may have 
suffered from the Software as a result of a fault on the part of the 
relevant Licensor, subject to providing evidence thereof.

8.2 The Licensor's liability is limited to the commitments made under 
this 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) direct or consequential loss that is suffered by 
the Licensee due to the use or performance of the Software, and (iii)

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).

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.
