# Usage: this script does not require any arguments. It uses the defaults in the configuration files.
# If using anvil, make sure the KEY_FILE points at anvil and run anvil in a separate window.
# If using testnet, configure the KEY_FILE to point at testnet.
#
# To run the script:
# python register-for-demo.py
#
# The script will deploy new Chainmail smart-contract to the blockchain, register an email address and an email message.
# The script will verify the registration and output "Success" if all goes well.
