DBIx::Class::Storage::DBI::ODBC::Firebird - Driver for using the Firebird RDBMS
through ODBC
-=head1 SYNOPSIS
+=head1 DESCRIPTION
Most functionality is provided by L<DBIx::Class::Storage::DBI::Interbase>, see
that module for details.
L<http://www.firebirdnews.org/?p=1324>
-=cut
+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>.

=head1 CAVEATS
This driver (unlike L<DBD::InterBase>) does not currently support reading or
writing C<TIMESTAMP> values with sub-second precision.

-Releasing savepoints does not work, but you should still be able to safely use
-savepoints.
