# Parameters are normalized to ensure Dockerfile can be called using:
#   1. Double quoted parameter value chains
#       E.g. "--parameter value" "--parameter2 value"
#       Designed for GitHub actions as action.yml args is sent this way.
#       Parameter value chains are parsed to send in unquoted format
#   2. Parameter value chain
#       This is the normal usage, parameters are sent through as they are
#       E.g. --parameter value --parameter2 value
# See ./tests/docker-entrypoint for testing it locally
