@interface NSFileWrapper (KSFileWrapperExtensions)
// Like -addFileWrapper:, but if you supply a subdirectory the wrapper will be added as a grandchild (or deeper), rather than child

#pragma mark Writing
// Simulates the behaviour NSFileWrapper gives you when writing a package, whereby files inside are hardlinked if possible. This method allows you to write an individual file and have it hard linked if possible

// Just the like the above but very specialist allowing you to give up should hard linking fail, and not bother spending time doing a full copy
