# This Awk script reads in the option records generated from

# This program uses functions from opt-functions.awk and code from

# Usage: awk -f opt-functions.awk -f opt-read.awk -f optc-save-gen.awk \
#            [-v header_name=header.h] < inputfile > options-save.c

# Dump that array of options into a C file.
