     50 Usage: ${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.
