-/* makes a bignum test harness with NUM tests per operation
- *
- * the output is made in the following format [one parameter per line]
-
-operation
-operand1
-operand2
-[... operandN]
-result1
-result2
-[... resultN]
-
-So for example "a * b mod n" would be
-
-mulmod
-a
-b
-n
-a*b mod n
-
-e.g. if a=3, b=4 n=11 then
-
-mulmod
-3
-4
