-"""Common wrapper over Python Qt bindings:
-
-- `PyQt5 <http://pyqt.sourceforge.net/Docs/PyQt5/>`_,
-- `PyQt4 <http://pyqt.sourceforge.net/Docs/PyQt4/>`_ or
-- `PySide <http://www.pyside.org>`_.
-
-If a Qt binding is already loaded, it will use it, otherwise the different
-Qt bindings are tried in this order: PySide2, PyQt4, PySide, PyQt5.
-
-The name of the loaded Qt binding is stored in the BINDING variable.
-
-For an alternative solution providing a structured namespace,
-see `qtpy <https://pypi.python.org/pypi/QtPy/>`_ which
-provides the namespace of PyQt5 over PyQt4, PySide and PySide2.
