 *************************************************************************

 The Amiga version only comes with makefile for PPC (and a precompiled libalgo.a)
 plus a test program. However, it should be really simple to do a 68k version.

 The test program demonstrates

    "--'strong' Goldbach's Conjecture
        The Conjecture is, "Every even integer >= 4 is the sum of
        two primes.--"

 by performing am_goldbach on 16 by default. Alternatively one can
 say

    test [number]

 which will work for even numbers and give an error for odd numbers...
