I'd like to make a Cocoa document-based application that opens arbitrary folders as documents. By this I mean regular folders as they appear in Finder, not bundles or packages. When a document is open, it represents that folder (so the title bar icon will be the folder), and will only be valid if specific file types are inside that folder (same pattern as with package documents, but without real packages). I can't use packages because the same data is read by another program that doesn't support packages.
How can I do that? The skeletal project as generated by Xcode seems to only facilitate files or package-folders, with specific extension.
