+
+Gruntmaster::Data - Gruntmaster 6000 Online Judge -- database interface and tools
+
+=head1 SYNOPSIS
+
+  for my $problem (problems) {
+    say "Problem name: " . problem_name $problem;
+    say "Problem level: " . problem_level $problem;
+    ...
+  }
+
+=head1 DESCRIPTION
+
+Gruntmaster::Data is the Redis interface used by the Gruntmaster 6000 Online Judge. It exports many functions for talking to the database. All functions are exported by default.
+
+The current contest is selected by setting the C<< $Gruntmaster::Data::contest >> variable.
+
+  local $Gruntmaster::Data::contest = 'mycontest';
+  say 'There are' . jobcard . ' jobs in my contest';
+
+=head1 FUNCTIONS
+

+Gruntmaster::Data exports some functions for talking directly to the Redis server. These functions should not normally be used, except for B<MULTI>, B<EXEC>, B<PUBLISH>, B<SUBSCRIBE> and B<WAIT_FOR_MESSAGES>.
+
+These functions correspond to Redis commands. The current list is: B<< MULTI EXEC SMEMBERS GET HGET HDEL HSET SADD SREM INCR HMSET HSETNX DEL PUBLISH SUBSCRIBE WAIT_FOR_MESSAGES >>.
