   7 Summary:
   8     G2HEC's pseudo random number seeding tool.  It first tries to use
   9     the file /dev/urandom as a source of random bits.  If it fails,
  10     then G2HEC falls back to deterministic random number generator.
  11     Upon successful execution, a seed of 128 bits is returned.
