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