I really like this idea. I was always a little uncomfortable with the 
tight relationship between the reading of the module file and the 
writing out of its data. For example, jsign and the changes to support 
listing the module file contents does some funnies to avoid writing out 
the actual contents. A pull parser type API may work well here. I'll 
take a stab at what this would look like ( unless you want to? ).

Yes, I agree. If jpkg evolves into a tool for creating and inspecting 
module files/native packages, then I think 'extract' is better suited in 
jpkg.
