+//
+// This test insures that google/protobuf/descriptor.pb.{h,cc} match exactly
+// what would be generated by the protocol compiler.  These files are not
+// generated automatically at build time because they are compiled into the
+// protocol compiler itself.  So, if they were auto-generated, you'd have a
+// chicken-and-egg problem.
+//
+// If this test fails, run the script
+// "generate_descriptor_proto.sh" and add
+// descriptor.pb.{h,cc} to your changelist.
