80 This package implements two useful features for customizing resultset classes.
81 C<load_resultset_components> loads components in addition to C<DBIx::Class::ResultSet>
82 (or whatever you set as C<base_resultset_class>). Any methods tagged with the C<ResultSet>
83 attribute will be moved into a table-specific resultset class (by default called
84 C<Class::_resultset>).
