# canonical_grade --grade <grade-to-be-canonicalized>
#
# This script is meant to be used mainly during the autoconfiguration process.
# It is meant to be invoked with a --grade <grade> option, whose value should
# be a possibly noncanonical grade name given by a human as part of an argument
# to the configure script. The job of this script is to print the canonical
# name of the grade. The script fails after printing an error message if the
# purported "grade" given is not a grade at all, not even a non-canonical one.
