1 /* LibTomMath, multiple-precision integer library -- Tom St Denis
3 * LibTomMath is library that provides for multiple-precision
4 * integer arithmetic as well as number theoretic functionality.
6 * The library is designed directly after the MPI library by
7 * Michael Fromberger but has been written from scratch with
8 * additional optimizations in place.
10 * The library is free for all purposes without any express
