+CeCILL-C FREE SOFTWARE LICENSE AGREEMENT
+
+
+    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-C (for Ce[a] C[nrs] I[nria] L[ogiciel] L[ibre])
+license are:
+
+Commissariat � 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 re-use the software governed by this license.
+
+The exercising of this right is conditional upon the obligation to make
+available to the community the modifications made to the source code of
+the software so as to contribute to its evolution.
+
+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.

+
+The Licensee is authorized to distribute true copies of the Software in
+Source Code or Object Code form, provided that said distribution
+complies with all the provisions of the Agreement and is accompanied by:
+
+   1. a copy of the Agreement,
+
+   2. a notice relating to the limitation of both the Licensor's
+      warranty and liability as set forth in Articles 8 and 9,
+
+and that, in the event that only the Object Code of the Software is
+redistributed, the Licensee allows effective access to the full Source
+Code of the Software at a minimum during the entire period of its
+distribution of the Software, it being understood that the additional
+cost of acquiring the Source Code shall not exceed the cost of
+transferring the data.
+
+
+        5.3.2 DISTRIBUTION OF MODIFIED SOFTWARE
+
+When the Licensee makes an Integrated Contribution to the Software, the
+terms and conditions for the distribution of the resulting Modified
+Software become subject to all the provisions of this Agreement.
+
+The Licensee is authorized to distribute the Modified Software, in
+source code or object code form, provided that said distribution
+complies with all the provisions of the Agreement and is accompanied by:
+
+   1. a copy of the Agreement,
+
+   2. a notice relating to the limitation of both the Licensor's
+      warranty and liability as set forth in Articles 8 and 9,
+
+and that, in the event that only the object code of the Modified
+Software is redistributed, the Licensee allows effective access to the
+full source code of the Modified Software at a minimum during the entire
+period of its distribution of the Modified Software, it being understood
+that the additional cost of acquiring the source code shall not exceed
+the cost of transferring the data.
+
+
+        5.3.3 DISTRIBUTION OF DERIVATIVE SOFTWARE
+
+When the Licensee creates Derivative Software, this Derivative Software
+may be distributed under a license agreement other than this Agreement,
+subject to compliance with the requirement to include a notice
+concerning the rights over the Software as defined in Article 6.4.
+In the event the creation of the Derivative Software required modification 
+of the Source Code, the Licensee undertakes that:
+
+   1. the resulting Modified Software will be governed by this Agreement,
+   2. the Integrated Contributions in the resulting Modified Software
+      will be clearly identified and documented,
+   3. the Licensee will allow effective access to the source code of the
+      Modified Software, at a minimum during the entire period of
+      distribution of the Derivative Software, such that such
+      modifications may be carried over in a subsequent version of the
+      Software; it being understood that the additional cost of
+      purchasing the source code of the Modified Software shall not
+      exceed the cost of transferring the data.
+
+
+        5.3.4 COMPATIBILITY WITH THE CeCILL LICENSE
+
+When a Modified Software contains an Integrated Contribution subject to
+the CeCILL license agreement, or when a Derivative Software contains a
+Related Module subject to the CeCILL license agreement, the provisions
+set forth in the third item of Article 6.4 are optional.
+
+
+    Article 6 - INTELLECTUAL PROPERTY
+
+
+      6.1 OVER THE INITIAL SOFTWARE
+
+The Holder owns the economic rights over the Initial Software. Any or
+all use of the Initial Software is subject to compliance with the terms
+and conditions under which the Holder has elected to distribute its work
+and no one shall be entitled to modify the terms and conditions for the
+distribution of said Initial Software.
+
+The Holder undertakes that the Initial Software will remain ruled at
+least by this Agreement, for the duration set forth in Article 4.2.
+
+
+      6.2 OVER THE INTEGRATED CONTRIBUTIONS
+
+The Licensee who develops an Integrated Contribution is the owner of the
+intellectual property rights over this Contribution as defined by
+applicable law.
+
+
+      6.3 OVER THE RELATED MODULES
+
+The Licensee who develops a Related Module is the owner of the
+intellectual property rights over this Related Module as defined by
+applicable law and is free to choose the type of agreement that shall
+govern its distribution under the conditions defined in Article 5.3.3.
+
+
+      6.4 NOTICE OF RIGHTS
+
+The Licensee expressly undertakes:
+
+   1. not to remove, or modify, in any manner, the intellectual property
+      notices attached to the Software;
+
+   2. to reproduce said notices, in an identical manner, in the copies
+      of the Software modified or not;
+
+   3. to ensure that use of the Software, its intellectual property
+      notices and the fact that it is governed by the Agreement is
+      indicated in a text that is easily accessible, specifically from
+      the interface of any Derivative Software.
+
+The Licensee undertakes not to directly or indirectly infringe the
+intellectual property rights of the Holder and/or Contributors on the
+Software and to take, where applicable, vis-�-vis its staff, any and 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) 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).
+
+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 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.
+
+
+    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.
