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

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