  85 Usage: $script_name [OPTIONS] IMAGE
  86
  87   -i, --iso                Make an ISO image instead of a disk image.
  88   -o, --only-wim           Make neither a disk image nor an ISO image;
  89                               instead, only make a modified boot.wim file.
  90   -W, --windows-dir=DIR    Use DIR as the location of the mounted Windows 7
  91                               or Windows 8 DVD.  Default is /mnt/windows,
  92                               then /mnt/windows7, then /mnt/windows8.
  93   -A, --waik-dir=DIR       Get the boot files and boot.wim from the ISO of the
  94                               Windows Automated Installation Kit mounted on DIR
  95                               instead of from the Windows 7 or Windows 8 DVD.
  96                               This also works if the mounted ISO is for the
  97                               WAIK supplement rather than the WAIK itself.
  98   -s, --start-script=FILE  Add FILE to the root directory of Windows PE image
  99                               and adjust \Windows\System32\winpeshl.ini to
 100                               execute FILE when Windows PE starts up.
 101   -w, --wim=WIM            Use WIM as the boot.wim file.  This defaults to the
 102                               appropriate WIM file from the Windows DVD, WAIK,
 103                               or WAIK supplement.
 104   -O, --overlay=DIR        Adds all the files in DIR to the Windows PE image.
 105   -t, --tmp-dir=DIR        Use DIR as the temporary base of the ISO filesystem.
 106                               Defaults to making one using "mktemp -d".
 107   -a, --arch=ARCH          Use the Windows PE version from the WAIK that has
 108                               the CPU architecture ARCH.  Possible values:
 109                               "x86" or "amd64".  Default is "x86".
 110   -h, --help               Display this information.
 111   -v, --version            Show version information.
 112
 113   See \`man mkwinpeimg' for more information.
