50Usage: ${PROGNAME} fsimage sun4 [sun4c [sun4m [sun3|sun4d [sun3x|sun4u]]]]
51	Combine file system partitions for Sun Microsystems, Inc. computers
52	into a CD-ROM file sytem image suitable for booting on the
53	following platforms:
54		NetBSD/sun3:	sun3, sun3x
55		NetBSD/sparc:	sun4, sun4c, sun4d, sun4m
56		NetBSD/sparc64:	sun4u
57	The architecture arguments must be bootable file system image
58	for that architecture, or \`-' if no entry is desired.
59	\`fsimage' is typically an iso9660 file system image, although
60	any time of file system can be used as long as the first 512
61	bytes of the image are not used.  \`fsimage' is modified, and
62	the additional partitions are added in order.  If the same
63	filename is used more than once for different architectures,
64	it will only be copied once.
