# This script constructs (or reconstructs) the contents of
# compiler/optimization_options.m. The initial and final parts
# are hand_written, in make_optimization_options_{start,end}
# respectively, while the middle is generated by
# make_optimization_options_middle from make_optimization_options_db.
#
# make_optimization_options_middle also generates handler_file,
# which is a code fragment that is intended to comprise part of
# the code of the special_handler predicate in compiler/options.m.
