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