Tooling to setup your joinmarket yield generator

    exec: Run the specified joinmarket script
    wallet-tool: Run wallet-tools.py on the wallet
    wallet-tool-generate: Generate a new wallet
    set-wallet: Set the wallet that the yield generator need to use
    logs: See logs of the yield generator (add -f to follow the logs)
    bash: Open an interactive bash session in the joinmarket container
    receive-payjoin: Receive a payjoin payment (this will stop the yield generator until the payment is received)
    sendpayment: Send a payjoin through coinjoin (password needed, this will stop the yield generator until the payment is received)
    start: Start the yield generator (started by default)
    stop: Stop the yield generator

Example:
    * jm.sh wallet-tool-generate
    * jm.sh set-wallet wallet.jmdat mypassword
    * jm.sh wallet-tool
    * jm.sh receive-payjoin
    * jm.sh sendpayment <address> <amount>
    * jm.sh wallet-tool history
    * jm.sh logs -f
    * jm.sh bash
    * jm.sh start
    * jm.sh stop
