Packages (was: copy large files in Rev on Mac)

[Chipp Walters]

So, if I understand this correctly, you can have a 'package' which is
a folder but not a 'bundle' but looks like one because it's 'bundle
bit' is on? :-)

On a more serious note, does the Mac have a registry like Windows? If
so, is it easy to gain access to? Rev has a single command to grab a
Window registry key. Perhaps a similar function for the Mac would
help?

I suppose the easiest thing to do, is to see how RevCopyFile manages
to figure out what a bundle/package/folder is and how to copy it
accurately (or does it?)
