Usage:
        From command line: ./bootstrap_tool.sh <command> <arg>
Supported commands:
        forger
        signer
Supported args:
        seed_size: Optional. Numeric. Default value 64.
Examples:
        ./bootstrap_tool.sh forger 128
        ./bootstrap_tool.sh signer
        export DOCKER_TAG=0.1.0 && ./bootstrap_tool.sh signer (default tag used is 'latest' but it can be selected via env variable)
Outputs:
