27 ;; This is a major mode for directory browsing and editing. It is
28 ;; documented in the Emacs manual.
30 ;; Rewritten in 1990/1991 to add tree features, file marking and
31 ;; sorting by Sebastian Kremer <sk@thp.uni-koeln.de>.
32 ;; Finished up by rms in 1992.

67 Example: if `ln -s foo bar; ls -F bar' gives `bar -> foo', set it to
68 nil (the default), if it gives `bar@ -> foo', set it to t.
70 Dired checks if there is really a @ appended. Thus, if you have a
