31 ;; Rewritten in 1990/1991 to add tree features, file marking and
32 ;; sorting by Sebastian Kremer <sk@thp.uni-koeln.de>.

56 may contain even `F', `b', `i' and `s'. See also the variable
57 `dired-ls-F-marks-symlinks' concerning the `F' switch.
58 On systems such as MS-DOS and MS-Windows, which use `ls' emulation in Lisp,
59 some of the `ls' switches are not supported; see the doc string of
60 `insert-directory' in `ls-lisp.el' for more details."

93 Set this to t if `ls' (or whatever program is specified by
94 `insert-directory-program') with `-lF' marks the symbolic link
95 itself with a trailing @ (usually the case under Ultrix).
97 Example: if `ln -s foo bar; ls -F bar' gives `bar -> foo', set it to
98 nil (the default), if it gives `bar@ -> foo', set it to t.
100 Dired checks if there is really a @ appended. Thus, if you have a
101 marking `ls' program on one host and a non-marking on another host, and
102 don't care about symbolic links which really end in a @, you can
103 always set this variable to t."
