Description: Internationalized Domain Names in Applications (IDNA)
        =====================================================
        
        A library to support the Internationalised Domain Names in Applications
        (IDNA) protocol as specified in `RFC 5891 <http://tools.ietf.org/html/rfc5891>`_.
        This version of the protocol is often referred to as “IDNA2008” and can 
        produce different results from the earlier standard from 2003.
        
        The library is also intended to act as a suitable drop-in replacement for
        the “encodings.idna” module that comes with the Python standard library
        but currently only supports the older 2003 specification.
        
        Its basic functions are simply executed:
        
        .. code-block:: pycon
        
            >>> import idna
            >>> idna.encode(u'ドメイン.テスト')
            'xn--eckwd4c7c.xn--zckzah'
            >>> print idna.decode('xn--eckwd4c7c.xn--zckzah')
            ドメイン.テスト
        
        Packages
        --------
        
        The latest tagged release version is published in the PyPI repository:
        
        .. image:: https://badge.fury.io/py/idna.svg
           :target: http://badge.fury.io/py/idna
        
        
        Installation
        ------------
        
        To install this library, you can use PIP:
        
        .. code-block:: bash
        
            $ pip install idna
        
        Alternatively, you can install the package using the bundled setup script:
        
        .. code-block:: bash
        
            $ python setup.py install
        
        This library should work with Python 2.7, and Python 3.3 or later.
        
        
        Usage
        -----
        
        For typical usage, the ``encode`` and ``decode`` functions will take a domain
        name argument and perform a conversion to an A-label or U-label respectively.
        
        .. code-block:: pycon
        
            >>> import idna
            >>> idna.encode(u'ドメイン.テスト')
            'xn--eckwd4c7c.xn--zckzah'
            >>> print idna.decode('xn--eckwd4c7c.xn--zckzah')
            ドメイン.テスト
        
        You may use the codec encoding and decoding methods using the
        ``idna.codec`` module.
        
        .. code-block:: pycon
        
            >>> import idna.codec
            >>> print u'домена.испытание'.encode('idna')
            xn--80ahd1agd.xn--80akhbyknj4f
            >>> print 'xn--80ahd1agd.xn--80akhbyknj4f'.decode('idna')
            домена.испытание
        
        Conversions can be applied at a per-label basis using the ``ulabel`` or ``alabel``
        functions if necessary:
        
        .. code-block:: pycon
        
            >>> idna.alabel(u'测试')
            'xn--0zwm56d'
        
        Compatibility Mapping (UTS #46)
        +++++++++++++++++++++++++++++++
        
        As described in RFC 5895, the IDNA specification no longer including mappings
        from different forms of input that a user may enter, to the form that is provided
        to the IDNA functions. This functionality is now a local user-interface issue
        distinct from the IDNA functionality.
        
        The Unicode Consortium has developed one such user-level mapping, known as
        `Unicode IDNA Compatibility Processing <http://unicode.org/reports/tr46/>`_.
        It provides for both transitional mapping and non-transitional mapping described
        in this document.
        
        .. code-block:: pycon
        
            >>> import idna
            >>> idna.encode(u'Königsgäßchen')
            ...
            idna.core.InvalidCodepoint: Codepoint U+004B at position 1 of u'K\xf6nigsg\xe4\xdfchen' not allowed
            >>> idna.encode(u'Königsgäßchen', uts46=True)
            'xn--knigsgchen-b4a3dun'
            >>> idna.encode(u'Königsgäßchen', uts46=True, transitional=True)
            'xn--knigsgsschen-lcb0w'
        
        Note that implementors should use transitional processing with caution as the outputs
        of the functions may differ from what is expected, as noted in the example.
        
        ``encodings.idna`` Compatibility
        ++++++++++++++++++++++++++++++++
        
        Function calls from the Python built-in ``encodings.idna`` module are
        mapping to their IDNA 2008 equivalents using the ``idna.compat`` module.
        Simply substitute the ``import`` clause in your code to refer to the
        new module name.
        
        Exceptions
        ----------
        
        All errors raised during the conversion following the specification should
        raise an exception derived from the ``idna.IDNAError`` base class.
        
        More specific exceptions that may be generated as ``idna.IDNABidiError``
        when the error reflects an illegal combination of left-to-right and right-to-left
        characters in a label; ``idna.InvalidCodepoint`` when a specific codepoint is
        an illegal character in an IDN label (i.e. INVALID); and ``idna.InvalidCodepointContext``
        when the codepoint is illegal based on its positional context (i.e. it is CONTEXTO
        or CONTEXTJ but the contextual requirements are not satisfied.)
        
        Testing
        -------
        
        The library has a test suite based on each rule of the IDNA specification, as
        well as test that are provided as part of the Unicode Technical Standard 46,
        `Unicode IDNA Compatibility Processing <http://unicode.org/reports/tr46/>`_.
        
        The tests are run automatically on each commit to the master branch of the
        idna git repository at Travis CI:
