      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.
     16 #	CRUNCHGEN_FLAGS	extra options to crunchgen(1)
     17 #	DESTDIR		destination directory
     18 #	PARSELISTENV	environment variables to set for parselist.awk

     20 # Variables modified by this:
     21 #	CRUNCHENV	may get SMALLPROG=1 or SMALLPROG_INET6=1 added
