Didn't work for me at all.

Sad to say, but I tried this today and didn't work.
I'm now in ssh console trying to dig around and find out why.

The method I used:
- openshift web interface - start a Python 2.7 gear with this repo as source. That worked.
- git clone to my system.
- edit production.cfg, commit, push back.
- got message that app started failed.
- login with ssh, find logs and check
**gunicorn not installed**
- tried to pip install that. worked. but now isso not installed.
- realized must be a virtualenv there. but trying to figure out now how to get correct python modules installed.
- seems requirements.txt was ignored.

Reproduce the deployment through the OpenShift web interface using the repository as the source, then inspect the application logs after editing and pushing production.cfg. Check how requirements.txt is handled and whether the deployment installs gunicorn and Isso. Done means the app starts successfully without manually installing missing Python modules.
