  Usage: $0 [command] [options]

  Commands:

  build - Build the docker images for the project.
          You need to do this first.

  up - Starts all containers and docker-compose logs.
       Use ctrl-c to exit logging. Use "down" or "stop" to stop the run.
        Examples:
        $0 start
        $0 start <ip_proxy_1>,<ip_proxy_2>,<ip_proxy_3>,<ip_proxy_4> &
  start - Same as up

  start-web - Start the web server to monitor an existing ledger, requires GENESIS_URL and LEDGER_SEED params
        Example:
        $0 start-web GENESIS_URL=http://foo.bar/genesis.txt LEDGER_SEED=00000000000000000000000000000012

  logs - Display the logs from the docker compose run (ctrl-c to exit).

  cli - Start client container

  down - Brings down the services and removes the volumes (storage) and containers.
  rm - Same as down

  stop - Stops the services.  This is a non-destructive process.  The volumes and containers
         are not deleted so they will be reused the next time you run start.

  rebuild - Rebuild the docker images.
