some of you may know that I've been studying Apple's Core Image API — specifically, how to write an Image Unit. I just found this, buried in Apple's website: Software Licensing & Trademark Agreements: Image Units.
what's special about that? read the page closely:
it's actually a command-line tool, and the agreement is displayed when the image is mounted rather than when the tool is run, but nonetheless — it's a tool that examines your Image Unit and attempts to compile its CI kernel, and tells you if it finds anything wrong. highly useful.
