I've written up a brief proposal about how "hidden" packages may be
supported in Koji. The objective of this is to enable building EPEL
packages in Koji. I wrote this up fairly quickly, and I'm sure I
haven't thought through all the issues, but I wanted to get the ball
rolling. Let me know if you have any questions/comments/ideas/issues
relating to this proposal.
