"""Black Mamba initialization module.

The only requirement is to call `blackmamba.main`. Example::

    import blackmamba
    blackmamba.main()

.. warning:: Do not add top level imports which depends on Pythonista modules. Module
    must be importable on any other platform. Add these imports to specific functions
    decorated with `blackmamba.system.Pythonista` and / or
    `blackmamba.system.iOS`.
