# Source this file ($ source <file-namne>) in your terminal to load all the
# functions.

# First run the looker-login using the client ID and client secret to generate
# an API token. Once you have your API token, run:
#
#   $ export LOOKER_API_TOKEN=<your-token>
#
# This will enable use of looker-curl.
