# This script is embedded in the docker image, and so the image must be updated when changes
# to the script are made. To do this, assuming you have docker installed:
# In tools/docker/ :
#   docker build .
#   docker ps # and look for the id of the image you just built
#   docker tag <image> <tag>
#   docker push <tag>
# Update the `image` specified in the project's .taskcluster.yml file
