abootimg binary package in Ubuntu Mantic amd64

 Android devices use a special partition format to boot any
 operating system on the devices. These boot-images contain
 a kernel image, a ramdisk, optionally a 2nd stage boot loader
 and the commandline passed to the kernel when booting.
 The original mkbootimg from Android can only create these images
 where abootimg can also extract and modify them.
 Handling android boot images is necessary when bringing other
 operating systems to android devices.
