+=head1 NAME
+
+DBIx::Class::Cursor - Abstract object representing a query cursor on a
+resultset.
+
+=head1 SYNOPSIS
+
+  my $cursor = $schema->resultset('CD')->cursor();
+  my $first_cd = $cursor->next;
+
+=head1 DESCRIPTION
+
+A Cursor represents a query cursor on a L<DBIx::Class::ResultSet> object. It
+allows for traversing the result set with L</next>, retrieving all results with
+L</all> and resetting the cursor with L</reset>.
+
+Usually, you would use the cursor methods built into L<DBIx::Class::ResultSet>
+to traverse it. See L<DBIx::Class::ResultSet/next>,
+L<DBIx::Class::ResultSet/reset> and L<DBIx::Class::ResultSet/all> for more
+information.
+
