A converter that allows an attribute to be optional. An optional attribute
is one which can be set to ``None``.
Type annotations will be inferred from the wrapped converter's, if it
has any.
:param callable converter: the converter that is used for non-``None``
values.

A converter that allows to replace ``None`` values by *default* or the
result of *factory*.
:param default: Value to be used if ``None`` is passed. Passing an instance
of `attrs.Factory` is supported, however the ``takes_self`` option
is *not*.
:param callable factory: A callable that takes no parameters whose result
is used if ``None`` is passed.
:raises TypeError: If **neither** *default* or *factory* is passed.
:raises TypeError: If **both** *default* and *factory* are passed.
:raises ValueError: If an instance of `attrs.Factory` is passed with
``takes_self=True``.

Convert "boolean" strings (e.g., from env. vars.) to real booleans.
Values mapping to :code:`True`:
- :code:`True`
- :code:`"true"` / :code:`"t"`
- :code:`"yes"` / :code:`"y"`
- :code:`"on"`
- :code:`"1"`
- :code:`1`
Values mapping to :code:`False`:
- :code:`False`
- :code:`"false"` / :code:`"f"`
- :code:`"no"` / :code:`"n"`
- :code:`"off"`
- :code:`"0"`
- :code:`0`
:raises ValueError: for any other value.
