10 The OpenMEEG software is a C++ package for solving the forward/inverse
11 problems of electroencephalography and magnetoencephalography.

13 This software is governed by the CeCILL-B license under French law and
14 abiding by the rules of distribution of free software. You can use,
15 modify and/ or redistribute the software under the terms of the CeCILL-B
16 license as circulated by CEA, CNRS and INRIA at the following URL

19 As a counterpart to the access to the source code and rights to copy,
20 modify and redistribute granted by the license, users are provided only
21 with a limited warranty and the software's authors, the holders of the
22 economic rights, and the successive licensors have only limited
23 liability.
24 
25 In this respect, the user's attention is drawn to the risks associated
26 with loading, using, modifying and/or developing or reproducing the
27 software by the user in light of its specific status of free software,
28 that may mean that it is complicated to manipulate, and that also
29 therefore means that it is reserved for developers and experienced
30 professionals having in-depth computer knowledge. Users are therefore
31 encouraged to load and test the software's suitability as regards their
32 requirements in conditions enabling the security of their systems and/or
33 data to be ensured and, more generally, to use and operate it in the
34 same conditions as regards security.
