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:

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.

    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.

Frequently asked questions can be found on the official website of the
CeCILL licenses family (http://www.cecill.info/index.en.html) for any
necessary clarification.

    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

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) more
generally, any consequential loss. In particular the Parties expressly
agree that any or all pecuniary 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.


    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 the Agreement, that may be attributable to an event of force
majeure, an act of God or an outside cause, such as defective
functioning or 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.


      11.5 LANGUAGE

The Agreement is drafted in both French and English and both versions
are deemed authentic.


    Article 12 - NEW VERSIONS OF THE AGREEMENT

12.1 Any person is authorized to duplicate and distribute copies of this
Agreement.

12.2 So as to ensure coherence, the wording of this Agreement is
protected and may only be modified by the authors of the License, who
reserve the right to periodically publish updates or new versions of 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
<#compatibility>.


    Article 13 - GOVERNING LAW AND JURISDICTION

13.1 The Agreement is governed by French law. The Parties agree to
endeavor to seek an amicable solution to any disagreements or disputes
that may arise during the performance of the Agreement.

13.2 Failing an amicable solution within two (2) months as from their
occurrence, and unless emergency proceedings are necessary, the
disagreements or disputes shall be referred to the Paris Courts having
jurisdiction, by the more diligent Party.

      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
