+Most functionality is provided by
+L<DBIx::Class::Storage::DBI::Firebird::Common>, see that driver for details.
 
 To build the ODBC driver for Firebird on Linux for unixODBC, see:
 
 L<http://www.firebirdnews.org/?p=1324>
 
 This driver does not suffer from the nested statement handles across commits
-issue that the L<DBD::InterBase|DBIx::Class::Storage::DBI::InterBase> based
-driver does. This makes it more suitable for long running processes such as
-under L<Catalyst>.
