 DBIx::Class::Storage::DBI::ODBC::Firebird - Driver for using the Firebird RDBMS
 through ODBC

-Most functionality is provided by L<DBIx::Class::Storage::DBI::Interbase>, see
-that module for details.
+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> or the
+L<DBD::Firebird|DBIx::Class::Storage::DBI::Firebird> based driver does. This
+makes it more suitable for long running processes such as under L<Catalyst>.
