+description:
+  Library to connect Yesod applications with PayPal's
+  <https://developer.paypal.com/docs/api/ REST API v1> by using the
+  <http://hackage.haskell.org/package/paypal-rest-client paypal-reset-client>
+  package. For documentation, see the
+  <https://github.com/meoblast001/yesod-paypal-rest/blob/master/README.md README>.
+  Due to the experimental nature of the paypal-rest-client, it is recommended to
+  explicitly give an exact version of that package even when you are already
+  including this package.
