/**
 * \mainpage 
 * 
 * M4RI is a library to do fast arithmetic with dense matrices over
 * \f$F_2\f$. It was started by Gregory Bard and is now maintained by
 * Martin Albrecht and Gregory Bard. This library implements Kronrod's
 * method (or "Method of the Four Russians") for matrix multiplication
 * and the "Method of the Four Russians Inversion" algorithm for
 * matrix reduction. The Strassen-Winograd matrix multiplication
 * algorithm is also implemented.
 *
 * M4RI is available under the GPLv2+ and used by the Sage mathematics
 * software and the PolyBoRi library. See
 * http://m4ri.sagemath.org for details.
