 This gem provides access to PayPal's Adaptive Payments API using easy-to-use
-ruby classes.  The internals are largely backed by

 [Virtus](https://github.com/solnic/virtus) and
 [RestClient](https://github.com/archiloque/rest-client), and so are easy to
 work with.

+effectively models that are declarative in nature.
