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.
