# A script to update the references for particular tests. The idea is
# that you do a run, which will generate files in the build directory
# containing the (normalized) actual output of the compiler. This
# script will then copy that output and replace the "expected output"
# files. You can then commit the changes.
#
# If you find yourself manually editing a foo.stderr file, you're
# doing it wrong.
