// TODO(kenton):  It's hard to write a robust test of the doc comments -- we
//   can only really compare the output against a golden value, which is a
//   fairly tedious and fragile testing strategy.  If we want to go that route,
//   it probably makes sense to bite the bullet and write a test that compares
//   the whole generated output for unittest.proto against a golden value, with
//   a very simple script that can be run to regenerate it with the latest code.
//   This would mean that updates to the golden file would have to be included
//   in any change to the code generator, which would actually be fairly useful
//   as it allows the reviewer to see clearly how the generated code is
//   changing.
