Subject Re: KAR feature not doing what the docs say it should
Date Wed, 02 Mar 2011 06:34:45 GMT
I'm not sure to follow you.

The kar goal is exactly as the add-features-to-repo goal: you start from 
a features descriptor (that you wrote by hand) and the goal package the 
descriptor and the bundles/dependencies into a repo (kar or local).

I consider that a non-starter.
