Comment 2 for bug 1499462

Upon further investigation, the Ubuntu packages for Liberty include the wsgi-keystone-public and wsgi-keystone-admin files and put them in the /usr/bin directory. Prior versions did not include any files for Apache/WSGI, so the installation guide pulled them (particularly keystone.py) from the git repository. I'm closing this issue and updating the installation guide to use the files in the /usr/bin directory, at least on Ubuntu. Not sure about other distributions yet.
