        //to test the upsp used below code
        USPSManager m = new USPSManager("USERID", false);
        Package p = new Package();
        p.FromAddress.Contact = "John Smith";
        p.FromAddress.Address2 = "475 L'Enfant Plaza, SW";
        p.FromAddress.City = "Washington";
        p.FromAddress.State = "DC";
        p.FromAddress.Zip = "20260";
        p.FromAddress.ZipPlus4 = "2060";

        p.WeightInOunces = 2;
        p.ServiceType = ServiceType.Priority;
        p.SeparateReceiptPage = false;
        p.LabelImageType = LabelImageType.PDF;
        p.PackageSize = PackageSize.Regular;
        p.PackageType = PackageType.Flat_Rate_Box;
        //  p.ShippingLabel=
