    Define an *attrs* class.

    Differences to the classic `attr.s` that it uses underneath:

    - Automatically detect whether or not *auto_attribs* should be `True` (c.f.
      *auto_attribs* parameter).
    - Converters and validators run when attributes are set by default -- if
      *frozen* is `False`.
    - *slots=True*

      .. caution::

         Usually this has only upsides and few visible effects in everyday
         programming. But it *can* lead to some surprising behaviors, so please
         make sure to read :term:`slotted classes`.
    - *auto_exc=True*
    - *auto_detect=True*
    - *order=False*
    - Some options that were only relevant on Python 2 or were kept around for
      backwards-compatibility have been removed.

    Please note that these are all defaults and you can change them as you
    wish.

    :param Optional[bool] auto_attribs: If set to `True` or `False`, it behaves
       exactly like `attr.s`. If left `None`, `attr.s` will try to guess:

       1. If any attributes are annotated and no unannotated `attrs.fields`\ s
          are found, it assumes *auto_attribs=True*.
       2. Otherwise it assumes *auto_attribs=False* and tries to collect
          `attrs.fields`\ s.

    For now, please refer to `attr.s` for the rest of the parameters.

       *unsafe_hash* as an alias for *hash* (for :pep:`681` compliance).

        Making this a wrapper ensures this code runs during class creation.

        We also ensure that frozen-ness of classes is inherited.
        NFz@Frozen classes can't use on_setattr (frozen-ness was inherited).T)r   ZNO_OPr	   	__bases____setattr__r   

    removed.

       The *type* parameter has been re-added; mostly for `attrs.make_class`.
