+
+DBIx::Class::Storage::DBI::Sybase::ASA - Driver for Sybase SQL Anywhere
+
+=head1 DESCRIPTION
+
+This class implements autoincrements for Sybase SQL Anywhere and selects the
+RowNumberOver limit implementation.
+
+You need the C<DBD::SQLAnywhere> driver that comes with the SQL Anywhere
+distribution, B<NOT> the one on CPAN. It is usually under a path such as:
