-D Enables debugging output (if available) to be printed. (default: off)
-no-checks Turns off all checks - use with caution! (default: checks on)
-C <num> The size of the cache (a prime number), 0 for full cache and -1 to turn it off. (default: 250007)
-O <num> The Omega parameter. (default: 1.0)
-S <num> The Sigma parameter. (default: 1.0)
