-"""Script to generate ARM beagleboard SD card image from kernel, root fs
-
-This script must be passed a uImage file and a tarred up root filesystem.
-It also needs EITHER an output device or a file + size. If you use a real
-device, the entire device will be used. if you specify a file, the file
-will be truncated to the given length and be formatted as a disk image.
-
-To copy a disk image to a device (e.g. /dev/sdb):
-# dd if=disk_image.img of=/dev/sdb bs=4M
