# This is the file baked into the OS X 10.8 VM image.
#
# Normally our VMs & containers actually have the cmd/buildlet/stage0
# binary baked-in, but the Mac VM images are extra painful to
# configure, so there's an extra level of indirection in their boot
# process to give us this point of flexibility. This shell script then
# downloads run-builder-darwin-10_8.gz which is the cmd/buildlet/stage0
# binary, compressed.
