#
# 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:
#	NETBSDSRCDIR	Top level of src tree (set by <bsd.own.mk>)
#	FLOPPYBASE	Basename of floppies. Floppy number ${n} will
#			be generated as ${FLOPPYBASE}${n}${FLOPPYSUFFIX}
#	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".
#	FLOPPYINSTBOOT		Installboot program to use.
#				USTAR image file is in @IMAGE@.
#	FLOPPYMAX		Maximum number of floppies to build.
#				If 1, the final image is installed as
#				${FLOPPYBASE}${FLOPPYSUFFIX} instead of
#				${FLOPPYBASE}1${FLOPPYSUFFIX}
#	FLOPPYMETAFILE		USTAR metafile(s) (optional)
#	FLOPPYPAD		If defined, pad the last floppy to ${FLOPPYSIZE}
#	FLOPPYSUFFIX		Suffix of created floppies.
#	FLOPPY_RELEASEDIR	Where to install release floppies.
