# for example, can execute this from hudson (with hudson
# lock) before promoting to staging directory, to make
# sure another build doesn't start while promoting, thereby
# erasing the build we are promoting.

# to end lock, the lockfile must be removed, which can be
# done manually, or as part of the script work
# There is a one-hour time-out built in, which should be plenty
