+
+// An empty message that you can re-use to avoid defining duplicated empty
+// messages in your project. A typical example is to use it as argument or the
+// return value of a service API. For instance:
+//
+//   service Foo {
+//     rpc Bar (grpc.testing.Empty) returns (grpc.testing.Empty) { };
+//   };
+//
+// MOE:begin_strip
+// The difference between this one and net/rpc/empty-message.proto is that
+// 1) The generated message here is in proto2 C++ API.
+// 2) The proto2.Empty has minimum dependencies
+//    (no message_set or net/rpc dependencies)
+// MOE:end_strip
