                FREE SOFTWARE LICENSING AGREEMENT CeCILL
                ========================================


Notice
------


This Agreement is a free software license that is the result of  discussions
between its authors  in  order  to  ensure  compliance  with  the  two  main
principles guiding its drafting:
   - firstly, its conformity with French law, both as  regards  the  law  of
     torts and intellectual property law, and the protection that it offers
     to authors and the holders of economic rights over software.
   - secondly, compliance with the principles for the distribution  of  free
     software: access to source codes, extended user-rights.

The following bodies are the authors of this license CeCILL (Ce : CEA, C :
CNRS, I : INRIA, LL : Logiciel Libre):

Commissariat à l'Energie Atomique - CEA, a public scientific, technical  and
industrial establishment, having its principal place of  business  at  31-33
rue de la Fédération, 75752 PARIS cedex 15, 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

PREAMBLE
--------


The purpose of this Free Software Licensing 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  ensure  that  this  status  is  retained  for  subsequent
redistribution operations.

As a counterpart to the access to the source code and 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, it is brought to the user's attention that the risks
associated  with loading, using, modifying and/or developing or reproducing
the  software  by the user given its nature of Free Software,  that  may  
mean that it is complicated to manipulate, and that also therefore means 
that it is reserved for developers and experienced professionals having
in-depth computer knowledge. Users are therefore encouraged to load and test
the Software's suitability  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 Articles 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 operation thereof to its provisions.

Article 9  - WARRANTY
---------------------


9.1. The  Licensee  acknowledges  that  the  current  situation  as  regards

distributed did not enable all possible uses to be tested and verified,  nor
for the presence of any or all faults 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  that  are
reserved for experienced users.

The Licensee shall be responsible for verifying, by any or  all  means,  the
product's suitability for its requirements, its due and proper  functioning,
and for ensuring that it  shall  not  cause  damage  to  either  persons  or
property.

9.2. The Licensor hereby represents, in good faith, that it is  entitled  to
grant all the rights on the  Software (including in  particular  the  rights
set forth in Article 5 hereof over the Software).

9.3. The Licensee acknowledges that the Software is supplied "as is" by  the
Licensor without any or all other express  or  tacit  warranty,  other  than
that provided for in Article 9.2 and, in  particular,  without  any  or  all
warranty as to its market  value,  its  secured,  innovative  or  relevant
nature.

Specifically, the Licensor does not warrant that the Software is  free  from
any or all error, that it shall  operate  continuously,  that  it  shall  be
compatible  with   the   Licensee's   own   equipment   and   its   software
configuration, nor that it shall meet the Licensee's requirements.

9.4. The Licensor does not either expressly  or  tacitly  warrant  that  the
Software does not  infringe  any  or  all  third  party  intellectual  right
relating to a patent, software or  to  any  or  all  other  property  right.
Moreover, the Licensor shall not hold the Licensee harmless against  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  upon  on  a  case-by-case
basis  between  the  relevant  Licensor  and  the  Licensee  pursuant  to  a
memorandum of understanding. The Licensor disclaims any or all liability  as
regards the Licensee's use of the Software's  name.  No  warranty  shall  be
provided as regards the existence of prior  rights  over  the  name  of  the
Software and as regards the existence of a trademark.

ineffective.

10.2. The  Licensee  whose  Agreement  is  terminated  shall  no  longer  be
authorized to use, modify or distribute the Software. However,  any  or  all
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 PROVISIONS
--------------------------------------


11.1. EXCUSABLE EVENTS

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

act of God or an outside cause, such as, notably, defective functioning,  or
interruptions affecting  the  electricity  or  telecommunications  networks,
blocking of the network following a virus attack, the  intervention  of  the
government authorities, natural disasters, water damage, earthquakes,  fire,
explosions, strikes and labor unrest, war, etc.

11.2. The fact that either Party may fail, on one or several  occasions,  to

its entitlement to invoke said provision(s) subsequently.

11.3. The Agreement cancels and replaces  any  or  all  previous  agreement,
whether written or oral, between the Parties and having  the  same  purpose,

conditions hereof shall be effective as regards the  Parties  unless  it  is
made in writing and signed by their duly authorized representatives.

11.4. In the event that one or several of  the  provisions  hereof  were  to
conflict with a current or future applicable act or legislative  text,  said
act or legislative text shall take precedence, and the  Parties  shall  make

legislative  text.  All  the  other  provisions  shall   remain   effective.
Similarly, the fact that a provision of  the  Agreement  may   be  null  and
void, for any reason whatsoever, shall not cause the Agreement  as  a  whole
to be null and void.

conflict as  regards  construction,  the  French  version  shall  be  deemed
