It uses hfsutils (emulators/hfsutils) to generate a template 5183863Snwhitehorn# filesystem with the relevant interesting files. These are then found by 6183863Snwhitehorn# grep, and the offsets written to a Makefile snippet. 7183863Snwhitehorn# 8183863Snwhitehorn# Because of licensing concerns, and because it is overkill, we do not 9183863Snwhitehorn# distribute hfsutils as a build tool.
