-// This defines the conformance testing protocol.  This protocol exists between
-// the conformance test suite itself and the code being tested.  For each test,
-// the suite will send a ConformanceRequest message and expect a
-// ConformanceResponse message.
-//
-// You can either run the tests in two different ways:
-//
-//   1. in-process (using the interface in conformance_test.h).
-//
-//   2. as a sub-process communicating over a pipe.  Information about how to
-//      do this is in conformance_test_runner.cc.
-//
-// Pros/cons of the two approaches:
-//
-//   - running as a sub-process is much simpler for languages other than C/C++.
-//
-//   - running as a sub-process may be more tricky in unusual environments like
-//     iOS apps, where fork/stdin/stdout are not available.
