-/* --- @strongprime_setup@ --- *

- * @pfilt *f@ = where to store filter jump context
- * @unsigned nbits@ = number of bits wanted
- * @grand *r@ = random number source

- *
- * Returns: A starting point for a `strong' prime search, or zero.
- *
- * Use: Sets up for a strong prime search, so that primes with
- * particular properties can be found. It's probably important
- * to note that the number left in the filter context @f@ is
- * congruent to 2 (mod 4).
