install:	$(PROGRAMS)
	/bin/cp ttyload ${INSTALLDIR}/ttyload

# because different systems' make have different behaviors on how they
# deal with building stuff in subdirectories, and because I don't feel
# like descending into the subdirectories to make a single object file,
# I'll force the .c.o rule to what I'm expecting:
