  14 # that you do a run, which will generate files in the build directory
  15 # containing the (normalized) actual output of the compiler. This
  16 # script will then copy that output and replace the "expected output"
  17 # files. You can then commit the changes.

  19 # If you find yourself manually editing a foo.stderr file, you're
  20 # doing it wrong.
