# This script builds two sets of artifacts:
#
#  1. the webpack bundles
#
#  2. at the tail end of this script, ./build-docker.sh is
#  invoked. That script builds a docker image that can be used to
#  serve up the webpack client. Try `npm start` when this script
#  finishes; this will start the docker container, allowing you to
#  debug your webpack client.
#
# Notes on build configuration: see /docs/dev/build-customization.md
