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

  43 =head1 DESCRIPTION
  44
  45 Gruntmaster::Daemon::Runner::Verifier is a runner which uses a verifier program to check the correctness of the output.
  46
  47 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.
