Best way to sign packages before adding to the repos?

[Chris Weyl]

Hey all--

Ok, so here's a question.  What's the best way to sign a package(s)
before adding it to the repository?  I was thinking that the easiest
way to do this would be while it's sitting in the "needsign/success"
state, but it looks like it's actually being added to the repository
before that state.

Is there an easy way to do this?  Or even a not-so-easy one?  <grin>
