9This Agreement is a Free Software license agreement that is the result
10of discussions between its authors in order to ensure compliance with
11the two main principles guiding its drafting:
12
13 * firstly, compliance with the principles governing the distribution
14 of Free Software: access to source code, broad rights granted to users,
15 * secondly, the election of a governing law, French law, with which it
16 is conformant, both as regards the law of torts and intellectual
17 property law, and the protection that it offers to both authors and
18 holders of the economic rights over software.

38 Preamble
39
40The purpose of this Free Software license agreement is to grant users
41the right to modify and redistribute the software governed by this
42license within the framework of an open source distribution model.
43
44The exercising of this right is conditional upon certain obligations for
45users so as to preserve this status for all subsequent redistributions.
46
47In consideration of access to the source code and the rights to copy,
48modify and redistribute granted by the license, users are provided only
49with a limited warranty and the software's author, the holder of the
50economic rights, and the successive licensors only have limited liability.
51
52In this respect, the risks associated with loading, using, modifying
53and/or developing or reproducing the software by the user are brought to
54the user's attention, given its Free Software status, which may make it
55complicated to use, with the result that its use is reserved for
56developers and experienced professionals having in-depth computer
57knowledge. Users are therefore encouraged to load and test the
58suitability of the software as regards their requirements in conditions
59enabling the security of their systems and/or data to be ensured and,
60more generally, to use and operate it in the same conditions of
61security. This Agreement may be freely reproduced and published,
62provided it is not altered, and that no provisions are either added or
63removed herefrom.
64
65This Agreement may apply to any or all software for which the holder of
66the economic rights decides to submit the use thereof to its provisions.
