echo Usage: build.cmd [latest/clean]
echo     Updates the working copy, cleans and builds the vm using nmake,
echo     fetches a boot image, and bootstraps factor.
echo     If latest is specified, then the working copy is updated to the
echo     upstream "master" branch and the boot image corresponding to the
echo     most recent factor build is downloaded. This is the default.
echo     If clean is specified, then the working copy is updated to the
echo     upstream "clean-windows-*" branch corresponding to the current
echo     platform and the corresponding boot image is downloaded.
