When was Squeak4.5? Five, six years ago? I haven’t looked at this in a while. I’ll need a bit of time to reflect.
I do seem to remember that the separation between application and data was pretty clear, so if you have a new application you can just point it to the right directory and it’ll set itself up. What I mean is if you wanted to replace the
wiki.squeak.org you should be able to park a new application over the existing directory of files and just turn it on. Mark Guzdial is a professor after all.
