   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.
