    '''
    The python3's recipe
    ^^^^^^^^^^^^^^^^^^^^

    The python 3 recipe can be built with some extra python modules, but to do
    so, we need some libraries. By default, we ship the python3 recipe with
    some common libraries, defined in ``depends``. We also support some optional
    libraries, which are less common that the ones defined in ``depends``, so
    we added them as optional dependencies (``opt_depends``).

    Below you have a relationship between the python modules and the recipe
    libraries::

        - _ctypes: you must add the recipe for ``libffi``.
        - _sqlite3: you must add the recipe for ``sqlite3``.
        - _ssl: you must add the recipe for ``openssl``.
        - _bz2: you must add the recipe for ``libbz2`` (optional).
        - _lzma: you must add the recipe for ``liblzma`` (optional).

    .. note:: This recipe can be built only against API 21+.

    .. versionchanged:: 2019.10.06.post0
        - Refactored from deleted class ``python.GuestPythonRecipe`` into here
        - Added optional dependencies: :mod:`~pythonforandroid.recipes.libbz2`
          and :mod:`~pythonforandroid.recipes.liblzma`

    .. versionchanged:: 0.6.0

27	The python3's recipe
28	^^^^^^^^^^^^^^^^^^^^
29
30	The python 3 recipe can be built with some extra python modules, but to do
31	so, we need some libraries. By default, we ship the python3 recipe with
32	some common libraries, defined in ``depends``. We also support some optional
33	libraries, which are less common that the ones defined in ``depends``, so
34	we added them as optional dependencies (``opt_depends``).
35
36	Below you have a relationship between the python modules and the recipe
37	libraries::
38
39	- _ctypes: you must add the recipe for ``libffi``.
40	- _sqlite3: you must add the recipe for ``sqlite3``.
41	- _ssl: you must add the recipe for ``openssl``.
42	- _bz2: you must add the recipe for ``libbz2`` (optional).
43	- _lzma: you must add the recipe for ``liblzma`` (optional).
44
45	.. note:: This recipe can be built only against API 21+.
46
47	.. versionchanged:: 2019.10.06.post0
48	- Refactored from deleted class ``python.GuestPythonRecipe`` into here
49	- Added optional dependencies: :mod:`~pythonforandroid.recipes.libbz2`
50	and :mod:`~pythonforandroid.recipes.liblzma`
51
