=head1 DESCRIPTION
-No documentation (yet)
+Gruntmaster::Data is the interface to the Gruntmaster 6000 database. Read the L<DBIx::Class> documentation for usage information.
+
+In addition to the typical DBIx::Class::Schema methods, this module contains several convenience methods:
+
+=over
+
+=item contests
+
+Equivalent to C<< $schema->resultset('Contest') >>
+
+=item contest_problems
+
+Equivalent to C<< $schema->resultset('ContestProblem') >>
+
+=item jobs
+
+Equivalent to C<< $schema->resultset('Job') >>
+
+=item problems
+
+Equivalent to C<< $schema->resultset('Problem') >>
+
+=item users
+
+Equivalent to C<< $schema->resultset('User') >>
+
+=item contest($id)
+
+Equivalent to C<< $schema->resultset('Contest')->find($id) >>
+
+=item job($id)
+
+Equivalent to C<< $schema->resultset('Job')->find($id) >>
+
+=item problem($id)
+
+Equivalent to C<< $schema->resultset('Problem')->find($id) >>
+
+=item user($id)
+
+Equivalent to C<< $schema->resultset('User')->find($id) >>
+
+=item user_list
+
+Returns a list of users as an arrayref containing hashrefs.
+
+=item user_entry($id)
+
+Returns a hashref with information about the user $id.
+
+=item problem_list([%args])
+
+Returns a list of problems grouped by level. A hashref with levels as keys.
+
+Takes the following arguments:
+
+=over
+
+=item owner
+
+Only show problems owned by this user
+
+=item contest
+
+Only show problems in this contest
+
+=back
+
+=item problem_entry($id, [$contest, $user])
+
+Returns a hashref with information about the problem $id. If $contest and $user are present, problem open data is updated.
+
+=item contest_list([%args])
+
+Returns a list of contests grouped by state. A hashref with the following keys:
+
+=over
+
+=item pending
+
+An arrayref of hashrefs representing pending contests
+
+=item running
+
+An arrayref of hashrefs representing running contests
+
+=item finished
+
+An arrayref of hashrefs representing finished contests
+
+=back
+
+Takes the following arguments:
+
+=over
+
+=item owner
+
+Only show contests owned by this user.
+
+=back
+
+=item contest_entry($id)
+
+Returns a hashref with information about the contest $id.
+
+=item job_list([%args])
+
+Returns a list of jobs as an arrayref containing hashrefs. Takes the following arguments:
+
+=over
+
+=item owner
+
+Only show jobs submitted by this user.
+
+=item contest
+
+Only show jobs submitted in this contest.
+
+=item problem
+
+Only show jobs submitted for this problem.
+
+=item page
+
+Show this page of results. Defaults to 1. Pages have 10 entries, and the first page has the most recent jobs.
+
+=back
+
+=item job_entry($id)
+
+Returns a hashref with information about the job $id.
+
