  39 Gruntmaster::Daemon::Runner::Verifier - Check the program output with a verifier

  43   use Gruntmaster::Daemon::Runner::Verifier;
  44   Gruntmaster::Daemon::Runner::Verifier::run(5, $meta);

  46 =head1 DESCRIPTION
  47
  48 Gruntmaster::Daemon::Runner::Verifier is a runner which uses a verifier program to check the correctness of the output.
  49
  50 The verifier program, C<< $meta->{files}{ver} >>, reads the test input from stdin and the output from fd 3. If the output is incorrect, it should return a nonzero value. Otherwise, it should print the score on this test and then return 0.
