Re. collisions, I specifically meant the same priority, yes. Thank you for looking into it!
The reason I ask is I want to know how my stuff behaves when other people download it -- i.e. when the resource.cfg is out of my control --, also for updates (I could perhaps do something more intelligent than replacing the entire file, if I can predict the behaviour).
Edit: on a related note, a quick Google search gives me very mixed results on the prospect of an OS X version (I believe that has a different idea of "alphanumerical" than most Windowses? Would the OS have an influence here?). Is there any official info on that yet? In case the load order is somehow determined by package name, I guess it would make sense to take any OSX-specific idiosyncrasies into account as well .. unless it's already clear that there won't ever be an OSX version)
