241 =head1 DESCRIPTION
242
243 Gruntmaster::Data is the interface to the Gruntmaster 6000 database. Read the L<DBIx::Class> documentation for usage information.
244
245 In addition to the typical DBIx::Class::Schema methods, this module contains several convenience methods:

249 =item contests
250
251 Equivalent to C<< $schema->resultset('Contest') >>
252
253 =item contest_problems
254
255 Equivalent to C<< $schema->resultset('ContestProblem') >>
256
257 =item jobs
258

267 Equivalent to C<< $schema->resultset('User') >>
268
269 =item contest($id)
270
271 Equivalent to C<< $schema->resultset('Contest')->find($id) >>
272
273 =item job($id)
274
275 Equivalent to C<< $schema->resultset('Job')->find($id) >>
276
277 =item problem($id)
278
279 Equivalent to C<< $schema->resultset('Problem')->find($id) >>
