=cut

use strict;

use List::MoreUtils qw/all/;

use YAML qw/Bless Dump/;
use Grades;

=head1 SYNOPSIS

scantron.pl -l emile -r 3 > exams/3/response.yaml

=cut

my $scantron = Grades::Script->new_with_options;
my $id = $scantron->league || basename( getcwd );
my $exam = $scantron->round;


=head1 DESCRIPTION

Makes it easy to transfer from paper subject/quiztopicform.tex quiz form, to exams/3/response.yaml. Also use nn, nun autogroups (:do nn User, :do nun User # see my vimrc) for one-touch data entry.

my $members = $league->members;
