-Cody added the script [primes.sh](1985/august/primes.sh) which allows one to

+Cody, out of abundance of caution, added a second arg to `main()` because some
+versions of clang object to the number of args of `main()`, saying that it must
+be 0, 2 or 3. The version this has been observed in does not actually object to
+1 arg but it is entirely possible that this changes so a second arg (that's not
+needed and is unused) has been added just in case.
