Available: lib for Paypal's Payment data transfer

Hi,

following the discussion about Paypal’s IPN usage with leetsoft’s
paypal library, I’ve posted an addition to that library so you can use
Paypal’s Payment Data Transfer.
It’s largely inspired by, with some chinks even simply copied from,
the IPN code.

Downloadable at http://www.myowndb.com/files/payment_data.rb
I blogged about it at Index of /blog where you can
find how to use it.

This is not yet in production, but is working fine with paypal’s
sandbox.

Hoping this can help someone. Let me know how it works for you.

Cheers.
