#
# Usage
# ----------
#	Standalone.Install.2005.0912.sh
#
#	-dev hda	use CompactFlash on /dev/hda
#	-dev sda	use USB-Stick on /dev/sda
#
#	-syslinux	use syslinux
#	-lilo		use lilo
#	-grub		use grub
#
#	-vfat		use vfat for /dev/sda1 ( aka /boot )
#
#	-X11		isntall x11 files
#	-KDE		install kde files
#
#
# ---------------------------------------------------------------------
# CAUTION: When moving the usb-stick or CompactFlash between machines
# ---------------------------------------------------------------------
#	- fix /boot/grub/devices.map for grub
#	- fix /boot/map for lilo

#
# 30-Aug-05 amo Date-of-Birth
# 06-Sep-05 amo Change to TGZ with datecode ( 0829 or 0831 )
# 11-Sep-05 amo Working kanji-KDE + fvwm menu
# 11-Sep-05 amo Release 2005.0911
# 12-Sep-05 amo Use global VER variable, redefine usage of TGZ
# 13-Sep-05 amo Option to install Lilo or Syslinux
# 15-Sep-05 amo Allow Grub and usb-modules should be built into the kernel
# 17-Sep-05 amo Test lilo vs grub
# 18-Sep-05 amo Added argv command line parsing
# 19-Sep-05 amo Fix file hierarchy for syslinux on usb-stick
# 24-Sep-05 amo Removed LOADER check, sometimes we only update initrd and roots, not lilo/grub
# 25-Sep-05 amo Added -vfat for /boot even for lilo 
# 28-Sep-05 amo Release 2005.0928, check for KDE-$VER and X11-$VER
