usage="
run-kyrix.sh: a script to start Kyrix docker containers. Usage:
    --help: show usage.
    --nba: run the NBA example upon start. You would need to wait the indexing for about a minute.
    --dbport PORT_NUMBER: specify the host port number of the postgres container. Default 5432.
    --kyrixport PORT_NUMBER: specify the host port number of the kyrix backend container. Default 8000.
    --postgis: start the DB container with postgis. You need to either start from scratch or run with --build to let docker rebuild the images.
    --build: rebuild the docker images before starting.
    --mavenopts: pass in custom Maven configuration. Default sets memory to 512MB.
    --stop: stop the containers.
    --down: remove containers, the network and volumes."
