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.
17 # mkisoimages.sh [-b] image-label image-name base-bits-dir [extra-bits-dir]
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.
