| 35 | |
| 36 | Gruntmaster::Daemon::Runner::Verifier - Check the program output with a verifier |
| 37 | |
| 38 | =head1 SYNOPSIS |
| 39 | |
| 40 | use Gruntmaster::Daemon::Runner::Verifier; |
| 41 | Gruntmaster::Daemon::Runner::Verifier::run(5, $meta); |
| 42 | |
| 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. |
