# This script will build the provided project, copy the zip file to S3 and then call

# Usage: ./update-lambda.sh [project name] [--quick] [function names...]
# eg. ./update-lambda.sh discount-api
# eg. ./update-lambda.sh --quick mparticle-api mparticle-api-http- mparticle-api-baton-

# Exit if any of these commands fail
