I consider the audit.spec file to be an example to help others with packaging. 
But I'm not entirely sure if it's 100% in sync with Fedora since they make 
arbitrary policy changes like removing gcc and make from the build root which 
then causes specfile updates. If you want to submit a patch, feel free. I 
would apply it as an example to others.
