    cat <<EOF
   $SCRIPTNAME [OPTIONS] -mbr=[DEVICE] [PARTITION]
     Installes LiveCD on PARTITION and the boot loader grub
     into the Master Boot Record (MBR) of DEVICE.
   OPTIONS:
     -h   --help         print this screen
     -swap=[partition]   use [partition] as swap
     -win=[partition]    your active Windows partition. If not given,
                         $SCRIPTNAME tries to find it
     -nogrub             do not install grub (leave MBR untouched)
     -floppy             needed, if grub should be installed on floppy
     -y                  answer all questions with yes
   Example:
   $SCRIPTNAME -swap=/dev/sda3 -mbr=/dev/sda /dev/sda2
     Will install LiveCD on /dev/sda2 (= second partition on
     first SATA disk). All data on /dev/sda2 will be deleted.
     /dev/sda3 has to be a Linux Swap partion. GRUB will be
     installed in the MBR of /dev/sda (= first SATA disk).
