/* 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.
