# Some notes and programs about make bootable USB device in MS windows are modified from http://www.pendrivelinux.com/, Thanks to PDLA.

You can find the keyboard layout in /usr/share/X11/xkb/rules/base.lst. e.g. use '-k fr' for French keyboard layout. If 'NONE' is used, the default one (US keyboard) will be use. For more info, please check the live manual on Debian Live website."

    echo "-y, --syslinux-ver VER  Assign the syslinux version as VER. E.g. 6.02, 6.03-pre1"
    echo "-z, --prefer-archive  PROG  Assign the archive program as PROG (tar or zip). Default program is $prefer_archive."
    echo "$prog will download a template Debian live CD for clonezilla iso file if ncecessary. You can also download it by yourself, and put it in the working directory when you run $prog. If you want to create that template iso file in Debian Etch, run create-debian-live."
