(( CeCILL 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
//** CeCILL¹ **//
__5__
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.

      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

      authorities, natural disasters, water damage, earthquakes, fire,

      (( 11.2 ))??
      Any failure by either Party, on one or more occasions, to invoke one or

      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.
