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

   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.

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
