+A script to build Imprudence for various OSes using qemu and virtual
+serial ports.
+
+Lot's of people wonder why I don't use ssh, the reason is that ssh
+requires both tho host and the guest computer to spend effort on
+encrypting the data stream that is only private between them anyway. 
+The poor things are working hard enough compiling the horendously huge
+viewer, the less overhead the better.  So the only thing using ssh gets
+you is to slow things down.
+
+
+Installing 64 bit Linux build image.
+====================================
+
+Get an Ubuntu 10.04.1 AMD64 desktop install CD image.
+
+Create a qemu disk image -
+qemu-img create -f qcow2 ubuntu64_base.qcow2 20G
+
+Start up qemu, booting from the CD image the first time -
+qemu-system-x86_64 -M pc -cpu qemu64 -m 1G -hda ubuntu64_base.qcow2 -cdrom ubuntu-10.04.1-desktop-amd64.iso -boot once=d
+
+Install Ubuntu.  Mostly select the defaults, except -
+Log in automatically.
+
+Update the system -
+apt-get update
+apt-get dist-upgrade
+
+Make sure this is in /etc/init/ttyS0.conf -
+start on stopped rc RUNLEVEL=[2345]
+stop on runlevel [!2345]
+respawn
+exec /sbin/getty -iLn -l /bin/bash 115200 ttyS0 vt102
+
+Install developmont stuff, and build time dependencies.
+apt-get install cmake binutils-gold bison build-essential flex git-core texinfo
+apt-get install freeglut3-dev libcrypto++-dev libgcrypt11-dev libgpg-error-dev libgsf-1-dev libmagic-dev libssl-dev libxinerama-dev libxrender-dev
+
+Shutdown qemu, then setup the snapshot -
+qemu-img create -f qcow2 -o backing_file=ubuntu64_base.qcow2 ubuntu64_diff.qcow2
+
+
+
+Installing 32 bit Linux build image.
+====================================
+
+Same as the 64 bit version above, but use Ubuntu 10.04.1 i386 desktop install CD, and use qemu-system-i386.
+
+
+Installing Windows XP build image.
+==================================
+
+Been a long time since I did this, forgot how.  These are the general tasks -
+
+create the disk image
+install under qemu
+reboot
+labourously install all the development stuff and build time dependencies
+reboot
+setup cygwin shell on serial port as a service
+reboot
+Then reboot more, coz it's Windows.
+
+
+Installing Mac build system.
+============================
+
+It's actually against Apples license for Mac OSX to install it on a VM
+that is not running on Apple branded hardware, so this time it has to be
+real Apple hardware.  When I actually get one, I'l make notes and get it
+to work.  This one likely needs to use ssh, don't think Mac's have
+serial ports.
