* Display only the synopsis on stdout * Keep a verbose log of all activity in the scratch directory. * Add more checks * Providing a directory argument will use the images found there instead of trying to extract them from the system (for use on host machines). Change-Id: I065a18c9467c625cc33484ee5556d955dc79b01d BUG=none TEST=manual Get a root shell and run "dev_debug_vboot". You should see nicer output. Review URL: http://codereview.chromium.org/4106001
