# STAND_ROOT is the root of a tree:
# cache - Cached binaries that we have downloaded
# trees - binary trees that we use to make image
#      trees/${ARCH}/$thing
# images - bootable images that we use to test
#	images/${ARCH}/$thing
# bios - cached bios images (as well as 'vars' files when we start testing
#	different booting scenarios in the precense / absence of variables).
# scripts - generated scripts that uses images to run the tests.
#
# Strategy:
#	Download FreeBSD release isos, Linux kernels (for the kboot tests) and
#	other misc things. We use these to generate dozens of test images that we
#	use qemu-system-XXXX to boot. They all boot the same thing at the moment:
#	an /etc/rc script that prints the boot method, echos success and then
#	halts.
