def METHOD_NAME(name: str, args: bool=False, usage: str="") -> None:
    """
    Defines a config setting of type `bool`.
    Allows the user invoking Tilt to configure a key named ``name`` to be in the
    dict returned by :meth:`parse`.
    For instance, at runtime, to set a flag of this type named `foo` to value `True`, run ``tilt up -- --foo``.
    To set a value to ``False``, you can run ``tilt up -- --foo=False``, or use a default value, e.g.::
      config.define_bool('foo')
      cfg = config.parse()
      do_stuff = cfg.get('foo', False)
    See the `Tiltfile config documentation <tiltfile_config.html>`_ for examples
    and more information.
    Args:
      name: The name of the config setting
      args: If False, the config setting is specified by its name. (e.g., if it's named "foo",
            ``tilt up -- --foo`` this setting would be ``True``.)
            If True, the config setting is specified by unnamed positional args. (e.g.,
            in ``tilt up -- True``, this setting would be ``True``.) (This usage
            isn't likely to be what you want)
      usage: When arg parsing fails, what to print for this setting's description.
