+=head1 NAME
+
+Gruntmaster::Daemon::Runner::Interactive - Make an interactive verifier talk to the program
+
+=head1 SYNOPSIS
+
+  use Gruntmaster::Daemon::Runner::Interactive;
+  Gruntmaster::Daemon::Runner::Interactive->run(5, $meta);
+
+=head1 DESCRIPTION
+
+B<WARNING: This runner is experimental!>
+
+Gruntmaster::Daemon::Runner::Interactive is a runner which runs the program and an interactive verifier in parallel, connecting each program's STDIN to the other's STDOUT. The verifier, C<< $meta->{files}{int} >>, should return nonzero if the program gives an incorrect answer, and print the test score to fd 4 then return 0 if the answer is correct.
