/* This is an independent implementation of the MARS encryption */
/* algorithm designed by a team at IBM as a candidate for the US */
/* NIST Advanced Encryption Standard (AES) effort. The algorithm */
/* is subject to Patent action by IBM, who intend to offer royalty */
/* free use if a Patent is granted. */
/* */
/* Copyright in this implementation is held by Dr B R Gladman but */
/* I hereby give permission for its free direct or derivative use */
/* subject to acknowledgment of its origin and compliance with any */
/* constraints that IBM place on the use of the MARS algorithm. */
