Usage: $0 [OPTION]
$0 prompts the user to set a password on the grub bootloader. The password
is written to a file named user.cfg which lives in the GRUB directory
located by default at ${grubdir}.

  -h, --help                     print this message and exit
  -v, --version                  print the version information and exit
  -o, --output_path &lt;DIRECTORY&gt;  put user.cfg in a user-selected directory
