# Convenience script for docker-compose
# Enables
#   - docker-compose and docker compose (v1, v2)
#   - moves multiple versions of unwieldy compose invocation to one place
#   - very convenient for starting and stopping containers when developing.
# Takes up to two arguments, typically "up -d", "start", and "stop"
# Always verifies docker and docker-compose, as it is run infrequently.
