+# 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.
