+A common problem is that an API is often developed in
+tandem with the client. Succulent is designed specifically to remove the effort
+in maintaining a specially built mock API by allowing you to record the current
+API and replay it back in unit and UI tests. This allows you to quickly update
+the tests when the API changes throughout your development cycle.
