The tar.gz source package on PyPi is broken and can't be installed.

[GrahamDumpleton]

When installing openshift package with version of pip that does't support wheels, or if use of wheels is disabled, the tar.gz source package on PyPi will fail to install.

$ pip install --no-use-wheel openshift
DEPRECATION: --no-use-wheel is deprecated and will be removed in the future.  Please use --no-binary :all: instead.

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/0p/4vcv19pj5d72m_bx0h40sw340000gp/T/pip-build-mNQ8Py/openshift/

This is because you haven't specified a MANIFEST.in file to list what extra files should be included in the source distribution package, such as requirements.txt.

Is this fixed with #71?
