# Usage: ./deploy.sh
#
# It infers the target for the deploy by the files under deploy_target_dir (see below).
# For each host you want to deploy to, put a file in there. Eg, for deploting to "alpha", put alpha.json in.
#
# ls ./deploy_targets
# => alpha.json
# ./deploy.sh
# => (deploys to alpha using alpha.json)
