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.
