My document format needs to look like:
File (actually a directory marked as a package)

In my NSDocument subclass, Overriding:
- (BOOL)readFromFileWrapper:(NSFileWrapper *)fileWrapper
ofType:(NSString *)typeName error:(NSError **)outError
Doesn't seem to be the right thing to do since it seems to want to put all
the files in a single flat directory within the package
It's the right place. You'll get a filewrapper representing the document-package
directory (the root). From there, you can query the root wrapper for
sub-wrappers using -fileWrappers (use -isDirectory and -isRegularFile to find
out if a wrapper contains other wrappers).
For writing the document, you'll overwrite -fileWrapperOfType:error: and return
a root wrapper that contains your entire package structure. You can construct
the interior of your package format to your liking, you can also add directories
by adding a file wrapper that represents a directory - created via
-initDirectoryWithFileWrappers:
The NSDocument guide contains a section about using wrappers and demos the
basics:
