 | |
|  *
 | |
|  * 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.
