# This script:
# - takes the name of the customer to demo for as first parameter
# - if provided a second parameter (issue number), goes in non-interactive mode

# In non-interactive mode:
# - creates a feature branch with name of customer
# - commits the feature code changes
# - comments on the provided issue how to create a pull request

# Required environment variables for non-interactive mode
# - OCTO_ORG: organization that holds the octocat generator repository
# - OCTO_REPO: octocat generator repo name
# - GITHUB_COM_TOKEN: PAT with write access to the OCTO_REPO

# In interactive mode (one parameter):
# - optionally creates a feature branch if ran on master
# - optionally commits the feature code changes
# - optionally pushes the commits to the same branch upstream
