 *
 *
 *  This version of MUMPS is provided to you free of charge. It is public
 *  domain, based on public domain software developed during the Esprit IV
 *  European project PARASOL (1996-1999). Since this first public domain
 *  version in 1999, research and developments have been supported by the
 *  following institutions: CERFACS, CNRS, ENS Lyon, INPT(ENSEEIHT)-IRIT,
 *  INRIA, and University of Bordeaux.
 *
 *  The MUMPS team at the moment of releasing this version includes
 *  Patrick Amestoy, Maurice Bremond, Alfredo Buttari, Abdou Guermouche,
 *  Guillaume Joslin, Jean-Yves L'Excellent, Francois-Henry Rouet, Bora
 *  Ucar and Clement Weisbecker.
 *
 *  We are also grateful to Emmanuel Agullo, Caroline Bousquet, Indranil
 *  Chowdhury, Philippe Combes, Christophe Daniel, Iain Duff, Vincent Espirat,
 *  Aurelia Fevre, Jacko Koster, Stephane Pralet, Chiara Puglisi, Gregoire
 *  Richard, Tzvetomila Slavova, Miroslav Tuma and Christophe Voemel who
 *  have been contributing to this project.
