Android Boot Image Tools

Packing/repacking Android boot images is annoying. Android Boot Image Tools makes it a breeze.

Dependencies

Make sure cpio, mkbootimg, and unmkbootimg are on your $PATH.

cpio seems to be fairly standard and shouldn't require special installation. mkbootimg/unmkbootimg can be found here: https://github.com/pbatard/bootimg-tools
