Ah, I see what you mean. Regarding runtime dependencies void is very 
forthcoming since it usually automatically detects them and you will not 
have to specify anything. You only need to add what cannot be detected 
automatically, and that boils down to the infos from the softwares author 
and what you can discern yourself by testing. I don't think that part can 
be significantly simplified since the possible ways one package can depend 
on another are so diverse. I would gladly be proven wrong though ;)
