# This script deploys examples to GCP so they can be statically hosted.
#
# The script can either be used without arguments, which deploys all demos:
# ./deploy.sh
# Or you can pass a single argument specifying a single demo to deploy:
# ./deploy.sh mnist
#
# This script assumes that a directory in this repo corresponds to an example.
#
# Example directories should have:
#  - package.json
#  - `yarn build` script which generates a dist/ folder in the example directory.
