// 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
