28 ;; The parts of dired mode not normally used. This is a space-saving hack
29 ;; to avoid having to load a large mode when all that's wanted are a few
30 ;; functions.
32 ;; Rewritten in 1990/1991 to add tree features, file marking and
33 ;; sorting by Sebastian Kremer <sk@thp.uni-koeln.de>.
34 ;; Finished up by rms in 1992.
36 ;;; Code:
38 ;; We need macros in dired.el to compile properly,
39 ;; and we call subroutines in it too.
