+=head1 NAME
+
+DBIx::Class::SQLMaker - An SQL::Abstract-based SQL maker class
+
+=head1 DESCRIPTION
+
+This module is a subclass of L<SQL::Abstract> and includes a number of
+DBIC-specific workarounds, not yet suitable for inclusion into the
+L<SQL::Abstract> core. It also provides all (and more than) the functionality
+of L<SQL::Abstract::Limit>, see L<DBIx::Class::SQLMaker::LimitDialects> for
+more info.
+
+Currently the enhancements to L<SQL::Abstract> are:
+
+=over
+
+=item * Support for C<JOIN> statements (via extended C<table/from> support)
+
+=item * Support of functions in C<SELECT> lists
+
+=item * C<GROUP BY>/C<HAVING> support (via extensions to the order_by parameter)
+
+=item * Support of C<...FOR UPDATE> type of select statement modifiers
