5 # This script is used by release/Makefile to build the (optional) ISO images
6 # for a FreeBSD release. It is considered architecture dependent since each
7 # platform has a slightly unique way of making bootable CDs. This script is
8 # also allowed to generate any number of images since that is more of
9 # publishing decision than anything else.

16 # whatever standards this architecture supports (may be unsupported),
17 # image-label is the ISO image label, image-name is the filename of the
18 # resulting ISO image, base-bits-dir contains the image contents and
19 # extra-bits-dir, if provided, contains additional files to be merged
20 # into base-bits-dir as part of making the image.
