| 31 | ;; This is Sebastian Kremer's excellent dired-x.el (Dired Extra), version |
| 32 | ;; 1.191, hacked up for GNU Emacs. Redundant or conflicting material has |
| 33 | ;; been removed or renamed in order to work properly with dired of GNU |
| 34 | ;; Emacs. All suggestions or comments are most welcomed. |
