	// than following the symlink and copying the file it points to.
	NoFollowSymlinks bool

	// PreCallback is called on each file to be copied before it is copied
	// if specified.
	//
	// If PreCallback returns ErrSkip, the file is skipped and Copy returns
	// nil.
	//
	// If PreCallback returns another non-nil error, the file is not copied
	// and Copy returns the error.
	PreCallback func(src, dst string, srcfi os.FileInfo) error

	// PostCallback is called on each file after it is copied if specified.
