# Gather common GCP environment info for quickly surveying new client environments
#
# Requires:
#
# - GCloud CLI to be available and configured 'gcloud init'
#   (or just use Cloud Shell, will prompt you to set the project if it's not already)
# - API services to be enabled (or to select Y to enable them when prompted)
# - Billing to be enabled in order to enable API services
#
# Tested with Google Cloud SDK installed locally
