33 | ;;; GNU Emacs 19. All suggestions or comments are most welcomed. | |

cb3fe1f0 RS |
87 | ;;; One drawback is that dired-x.el will load dired-aux.el as soon as dired is |
88 | ;;; loaded. Thus, the advantage of separating out non-essential dired stuff | |
89 | ;;; into dired-aux.el and only loading when necessary will be lost. Please | |
90 | ;;; note also that some of the comments in dired.el and dired-aux.el are | |
9572a9dd KH |
91 | ;;; Kremer's that referred to the old dired-x.el. This now should be referring |
92 | ;;; to this program. (This is also a good reason to call this dired-x.el | |
cb3fe1f0 RS |
