  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 time 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.
