# parse_grade_options.sh-subr:
#	An `sh' subroutine for parsing grade-related options.
#	Used by the `ml', `mgnuc' and `c2init' scripts.
#
#	The code here should be inserted in the case statement in a script's
#	option-parsing loop.
#
# 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 should handle the setting of all the shell variables defined by
# init_grade_options.sh-subr.
