+// To test the code generator, we actually use it to generate code for
+// net/proto2/internal/unittest.proto, then test that.  This means that we
+// are actually testing the parser and other parts of the system at the same
+// time, and that problems in the generator may show up as compile-time errors
+// rather than unittest failures, which may be surprising.  However, testing
+// the output of the C++ generator directly would be very hard.  We can't very
+// well just check it against golden files since those files would have to be
+// updated for any small change; such a test would be very brittle and probably
+// not very helpful.  What we really want to test is that the code compiles
+// correctly and produces the interfaces we expect, which is why this test
+// is written this way.
