29 ;; This is a major mode for directory browsing and editing. It is
30 ;; documented in the Emacs manual.
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.

52 "*Switches passed to `ls' for dired. MUST contain the `l' option.
53 May contain all other options that don't contradict `-l';
54 may contain even `F', `b', `i' and `s'. See also the variable
55 `dired-ls-F-marks-symlinks' concerning the `F' switch.
56 On systems such as MS-DOS and MS-Windows, which use `ls' emulation in Lisp,
57 some of the `ls' switches are not supported; see the doc string of
58 `insert-directory' on ls-lisp.el for more details."

81 Set this to t if `ls' (or whatever program is specified by
82 `insert-directory-program') with `-lF' marks the symbolic link
83 itself with a trailing @ (usually the case under Ultrix).
85 Example: if `ln -s foo bar; ls -F bar' gives `bar -> foo', set it to
86 nil (the default), if it gives `bar@ -> foo', set it to t.
88 Dired checks if there is really a @ appended. Thus, if you have a
89 marking `ls' program on one host and a non-marking on another host, and
90 don't care about symbolic links which really end in a @, you can
