#
# Makefile snippet to build a crunchgen(1)ed binary from the provided lists
#
# Required variables:
#	NETBSDSRCDIR	top level of src tree (set by <bsd.own.mk>)
#	CRUNCHBIN	name of crunchgen(1)ed binary
#	LISTS		list file(s) to use
#
# Optional variables:
#	SMALLPROG	if != 0, add SMALLPROG=1 to CRUNCHENV.  [default: 1]
#	SMALLPROG_INET6	if != 0 and SMALLPROG != 0, and ${USE_INET6} != "no",
#			add SMALLPROG_INET6=1 to CRUNCHENV.  [default: 0]
#	CRUNCHENV	environment to pass to crunchgen(1) and when building
#			the crunched program with make(1) (as command line
#			variables, to override any user provided environment
#			or make(1) cmdline vars).
#	CRUNCHGEN_FLAGS	extra options to crunchgen(1)
#	DESTDIR		destination directory
#	PARSELISTENV	environment variables to set for parselist.awk
#
# Variables modified by this:
#	CRUNCHENV	may get SMALLPROG=1 or SMALLPROG_INET6=1 added
#
