      This tool stores seed phrases in a local directory (~/.grdn),
      and allows you to organize them hierarchically. Seeds are
      AES-128 encrypted with a password (the same one for all seeds),
      and stored in a tree structure. This allows organization by
      purpose, location, application, wallet, or anything else you
      can think of. They can be nested as deeply as you want. This
      tool is not recommended for security-critical usecases.

    =================================================================

    Usage: grdn <command> [args]

    Commands:
      list                              List your seeds
      set a [b c d e f ...]             Add a seed
      get a [b c d e f ...]             Retrieve a seed
      remove a [b c d e f ...]          Remove a seed

    Example:
      The following commands:
        $ grdn set commerce development my.email+test@domain.com
        $ grdn set commerce production my.email@domain.com
        $ grdn set commerce production my.other.email@domain.com
        $ grdn set phone coinbase-wallet username
        $ grdn set laptop electrum default_wallet
        $ grdn set random

      would product this output:
        $ grdn list

        commerce
          development
            my.email+test@domain.com
          production
            my.email@domain.com
            my.other.email@domain.com
        laptop
          electrum
            default_wallet
        phone
          coinbase-wallet
            username
        random
