=head1 NAME

Gruntmaster::Daemon::Runner::File - Compare output with static text files

=head1 SYNOPSIS

  use Gruntmaster::Daemon::Runner::File;
  Gruntmaster::Daemon::Runner::File::run(5, $meta);

=head1 DESCRIPTION

Gruntmaster::Daemon::Runner::File is a runner which compares the program output for test C<$test> with a static output. Before comparing, leading and trailing whitespace is removed, and sequences of whitespace are converted to a single space.

If C<< $meta->{okfile} >> exists, the output is compared to C<< $meta->{okfile}[$test - 1] >>.
Otherwise, the output is compared to F<< /var/lib/gruntmasterd/pb/$meta->{problem}/$test.ok >>.

If the two strings match, the verdict is C<< $meta->{tests}[$test - 1] >>. Otherwise, the verdict is C<[WA, "Wrong answer"]>.
