  // sets up the PATH to point to the directory where the Dart VM was run from,
  // which will be unrelated to the path where pub itself is located when
  // running from pub's repo.

  // However, pub's repo doesn't actually have the shell scripts required to
  // run "pub". Those live in the Dart SDK repo. One fix would be to make shell
  // scripts in pub's repo that can act like those scripts but invoke pub from
  // source from the pub repo.
