+// GoMock - a mock framework for Go.
+//
+// Standard usage:
+//   (1) Define an interface that you wish to mock.
+//         type MyInterface interface {
+//           SomeMethod(x int64, y string)
+//         }
+//   (2) Use mockgen to generate a mock from the interface.
+//   (3) Use the mock in a test:
+//         func TestMyThing(t *testing.T) {
+//           mockCtrl := gomock.NewController(t)
+//           defer mockCtrl.Finish()
+//
+//           mockObj := something.NewMockMyInterface(mockCtrl)
+//           mockObj.EXPECT().SomeMethod(4, "blah")
+//           // pass mockObj to a real object and play with it.
+//         }
+//
+// By default, expected calls are not enforced to run in any particular order.
+// Call order dependency can be enforced by use of InOrder and/or Call.After.
+// Call.After can create more varied call order dependencies, but InOrder is
+// often more convenient.
+//
+// The following examples create equivalent call order dependencies.
+//
+// Example of using Call.After to chain expected call order:
+//
+//     firstCall := mockObj.EXPECT().SomeMethod(1, "first")
+//     secondCall := mockObj.EXPECT().SomeMethod(2, "second").After(firstCall)
+//     mockObj.EXPECT().SomeMethod(3, "third").After(secondCall)
+//
+// Example of using InOrder to declare expected call order:
+//
+//     gomock.InOrder(
+//         mockObj.EXPECT().SomeMethod(1, "first"),
+//         mockObj.EXPECT().SomeMethod(2, "second"),
