*
* Is an example of how to write Paypal IPN processors using the classes provided
* by dm.paypal from phpclasses.org. The overall process is pretty simple.
*
* 1. Create a class that extends paypalIPNBase.
* 2. Override the following methods:
*
* A. preprocess - called before any $_POST processing has occurred.
* B. [optional] sourceNotEmpty - called if there is any data left in $_POST after extracting Paypal IPN data.
* C. alternatePaymentStatus - called if the IPN is not a completed payment.
* D. checkTransactionId - called to determine if the transaction Id is unique in your application.
* E. processPayment - called when the payment has been fully verified.
* F. postprocess - called after any/all processing has occurred.
*
* 3. Create your Purchasing environment.
* 4. Configure Paypal to invoke your IPN page.
* 5. Test, test, test.
