   # ----------------------------------------------------------

   cat <<EOF

  $SCRIPTNAME [OPTIONS] -mbr=[DEVICE] [PARTITION | MOUNTED FILE SYSTEM]

    Installes LiveCD on PARTITION and the bootloader grub into 

    the Master Boot Record (MBR) of DEVICE. The MBR will be 

    backed up to PARTITION.

  OPTIONS:

    -h   --help          : Print this screen

    -swap=[partition(s)] : Use [partition(s)] as swap ("," or "|" separated)

    -win=[partition]     : Your active Windows partition. If not given, 

                           $SCRIPTNAME tries to find it

    -nogrub              : Do not install grub. You have to install 

                           manually a bootloader (not recommended)

    -floppy              : Needed, if grub should be installed on floppy

                           In this case use -mbr=/dev/fd0 -floppy

    -norpmremove         : Do not remove RPMs that can break future 

                           updates (not recommended)

    -fstype              : File system type (ext3,xfs,etc.), default is $FS_TYPE

    -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).

  Remarks:

    To display your hard disk partitions, user 'fdisk -l'.

    Use fdisk, qtparted or parted to create an empty Linux

    partition.
