  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).

  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.

  dockerhost - Print the ip address of the Docker Host Adapter as it is seen by containers running in docker.

  indy-cli - Run indy-cli commands.

        - Refer to the cli-scripts directory for available scripts and their parameters.
        - Refer to './docs/Writing Transactions to a Ledger for an Un-privileged Author.md' for
          additional examples.
        
        $0 [options] indy-cli [command] [parameters]

        Options:
          -v <FullyQualifiedPathToScripts/>
            - Mount a script volume to the container.
            - By default the 'cli-scripts' directory is mounted to the container.

        Examples:
        
        $0 indy-cli
          - Start an interactive indy-cli session in your Indy-Cli Container.

        $0 \\
          indy-cli create-wallet \\
          walletName=myorg_issuer \\
          storageType=default \\
          storageConfig='{}' \\
          storageCredentials='{}' \\
          walletSeed=0000000000000000000000000MyAgent

          - Create and initialize a new wallet in your Indy-Cli Container.

        $0 \\
          cli \\
          walletName=myorg_issuer \\
          storageType=default \\
          storageConfig='{}' \\
          storageCredentials='{}' \\
          walletDid=NFP8kaWvCupbDQHQhErwXb \\
          walletSeed=0000000000000000000000000MyAgent \\
          walletKey=key \\
          python cli-scripts/set_did_metadata.py

          - Set DID metadata on a wallet in your Indy-Cli Container.

  cli - Run a command in an Indy-Cli Container.  By default 
        
        $0 [options] cli [command]

        Options:
          -v <FullyQualifiedPathToScripts/>
            - Mount a script volume to the container.
            - By default the 'cli-scripts' directory is mounted to the container.
        
        Examples:
        
        $0 cli bash
          - Open a bash shell within your Indy-Cli Container

        $0 -v /MyScripts cli bash
          - Open a bash shell within your Indy-Cli Container.  Mount the `/MyScripts` directory to the container.

        $0 cli reset
          - Reset your Indy-CLI container's environment

        $0 cli init-pool localpool http://192.168.65.3:9000/genesis
        $0 cli init-pool MainNet https://raw.githubusercontent.com/sovrin-foundation/sovrin/stable/sovrin/pool_transactions_live_genesis
          - Initialize the pool for your Indy-CLI container's environment.
