# init_grade_options.sh-subr:
#   An `sh' subroutine for initializing grade-related options.
#   Used by the `ml', `mgnuc' and `c2init' scripts.
#
#   The code here should be inserted before a script's option-parsing
#   loop.  The invoking script must define a DEFAULT_GRADE option.
#
# IMPORTANT: any changes to the handling of grades here may also require
# changes to all the files indicated by runtime/mercury_grade.h.
#
# This file must initialize all the shell variables used by
# parse_grade_options.sh-subr, and must list all the options processed in
# parse_grade_options.sh-subr.
