-# Date:   22 June 2001
-#
-# $FreeBSD$
-#
-# This script is used by release/Makefile to build the (optional) ISO images
-# for a FreeBSD release.  It is considered architecture dependent since each
-# platform has a slightly unique way of making bootable CDs.  This script
-# is also allowed to generate any number of images since that is more of
-# publishing decision than anything else.
-#
-# Usage:
-#
-# mkisoimages.sh [-b] image-label image-name base-bits-dir [extra-bits-dir]
-#
-# Where -b is passed if the ISO image should be made "bootable" by
-# whatever standards this architecture supports (may be unsupported),
-# image-label is the ISO image label, image-name is the filename of the
-# resulting ISO image, base-bits-dir contains the image contents and
-# extra-bits-dir, if provided, contains additional files to be merged
-# into base-bits-dir as part of making the image.

-# getty The program to start running on the terminal.  Typically a
