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