+=head1 NAME
+
+ DBIx::Class::ResultSetManager - helpful methods for managing resultset classes (EXPERIMENTAL)
+
+=head1 SYNOPSIS
+
+ # in a table class
+ __PACKAGE__->load_components(qw/ResultSetManager/);
+ __PACKAGE__->load_resultset_components(qw/AlwaysRS/);
+
+ # will be removed from the table class and inserted into a table-specific resultset class
+ sub foo : resultset { ... }
+
+=head1 DESCRIPTION
+
+This package implements two useful features for customizing resultset classes.
+C<load_resultset_components> loads components in addition to C<DBIx::Class::ResultSet>
+(or whatever you set as C<base_resultset_class>). Any methods tagged with the C<ResultSet>
+attribute will be moved into a table-specific resultset class (by default called
+C<Class::_resultset>).
