Hi James,
I looked into the code, and (if I understand this correctly), this is ment to check the spec file before rpms are created?
What did you have in mind with the finger-food stuff? Checking up on autoqa specfile, or creating a new test which utilizes this tool?
If the second is right, then I'd rather waited until we have the 'independent test support' - we can possibly use this as a example for this idea ;-)
I haven't studied the tool, but according to description, this is not 'independent package test', but rather generic test that allows to check the spec file of every package build, right? In that case I'd propose creating a new ticket in Future tests milestone with link to that discussion thread.
