=head1 ABSTRACT

    This is a Business::OnlinePayment module for PaySystems loosely based on
    Business::OnlinePayment::AuthorizeNet.  I should allow capture, preauth,
    postauth capture, credit, and voids (last two are both refunds).

=head1 DESCRIPTION
    See Synopsis, all fields are required.  When doing a postauth, credit or
    void card number is not required, but the order_number of the preauth
    transaction is.  This can be retrieved using the order_number method.
    The authorization method can be used to retrieve the bank authorization
    code if it is important to know this.  Supports Visa, MasterCard,
    American Express, and Diners card.
