#
# Makefile snippet to create a set of ustar floppies.
# Each floppy has an 8KB header, followed by part or all of the ustar archive.
#

#
# Required variables:
#	_SRC_TOP_	Top level of src tree (set by <bsd.own.mk>)
#	FLOPPYBASE	Basename of floppies. Floppy number ${n} will
#			be generated as ${FLOPPYBASE}${n}.fs
#	FLOPPYSIZE	Size of floppy in 512 byte blocks.
#	FLOPPYFILES	Files to write to floppy.
#			Usually set to "boot ${FLOPPYMETAFILE} netbsd"
#

#
# Optional variables:
#	FLOPPY_BOOT		Bootstrap to use as "boot".
#	FLOPPY_BOOT_STRIP	If yes, strip "boot" before use.
#	FLOPPY_NETBSD		Kernel to to use as "netbsd".
#
#	FLOPPYMAX	Maximum number of floppies to build.
#			If 1, final image is installed as ${FLOPPYBASE}.fs
#	FLOPPYMETAFILE	Ustar metafile (optional)
#	FLOPPYINSTBOOT	Installboot program to use.  ustar file is in @IMAGE@.
#	FLOPPYPAD	If defined, pad the last floppy to ${FLOPPYSIZE}
#	FLOPPYINSTDIR	Where to install release images.
