# MKfallback.sh -- create fallback table for entry reads
#
# This script generates source code for a custom version of read_entry.c
# that (instead of reading capabilities for an argument terminal type
# from an on-disk terminfo tree) tries to match the type with one of a
# specified list of types generated in.
