 As described earlier, the ``.pyd`` file is normally copied to site-packages. I don't want to pollute the root folder, so the ``__init__.py`` file in cv2 folder handles the import logic correctly by importing the actual ``.pyd`` module and replacing the imported cv2 package in ``sys.modudes`` with the ``.pyd`` module.

 As Python's 2.x releases are slowly approaching legacy state, 2.7.x releases will be the only supported Python 2 versions. On Python 3 side, builds will be run only for the latest release which is at the moment 3.5.1.
