   9 # This script is used by release/Makefile to build the (optional) ISO images
  10 # for a FreeBSD release.  It is considered architecture dependent since each
  11 # platform has a slightly unique way of making bootable CDs.  This script
  12 # is also allowed to generate any number of images since that is more of
  13 # publishing decision than anything else.
  14 #
  15 # Usage:
  16 #
  17 # mkisoimages.sh [-b] image-label image-name base-bits-dir [extra-bits-dir]
  18 #
  19 # Where -b is passed if the ISO image should be made "bootable" by
  20 # whatever standards this architecture supports (may be unsupported),
  21 # image-label is the ISO image label, image-name is the filename of the
  22 # resulting ISO image, base-bits-dir contains the image contents and
  23 # extra-bits-dir, if provided, contains additional files to be merged
  24 # into base-bits-dir as part of making the image.
