      3 # Makefile snippet to build a crunchgen(1)ed binary from the provided lists
      4 #
      5 # Required variables:
      6 #	NETBSDSRCDIR	top level of src tree (set by <bsd.own.mk>)
      7 #	CRUNCHBIN	name of crunchgen(1)ed binary
      8 #	LISTS		list file(s) to use
      9 #
     10 # Optional variables:
     11 #	SMALLPROG	if != 0, add SMALLPROG=1 to CRUNCHENV.  [default: 1]
     12 #	SMALLPROG_INET6	if != 0 and SMALLPROG != 0, and ${USE_INET6} != "no",
     13 #			add SMALLPROG_INET6=1 to CRUNCHENV.  [default: 0]
     14 #	CRUNCHENV	environment to pass to crunchgen(1) and when building
     15 #			the crunched program with make(1) (as command line
     16 #			variables, to override any user provided environment
     17 #			or make(1) cmdline vars).
     18 #	CRUNCHGEN_FLAGS	extra options to crunchgen(1)
     19 #	DESTDIR		destination directory
     20 #	PARSELISTENV	environment variables to set for parselist.awk
     21 #
     22 # Variables modified by this:
     23 #	CRUNCHENV	may get SMALLPROG=1 or SMALLPROG_INET6=1 added
