;;

-;; the files in a "dired" buffer? Now you can do this. All the power

+;; (query-replace), M-c (capitalize-word), etc... to change the name of
+;; the files in a "dired" buffer? Now you can do this. All the power
+;; of Emacs commands are available to renaming files!
+;;
;; This package provides a function that makes the filenames of a a
;; dired buffer editable, by changing the buffer mode (which inhibits
;; all of the commands of dired mode). Here you can edit the names of
;; one or more files and directories, and when you press C-c C-c, the
;; renaming takes effect and you are back to dired mode.
;;
-;; Another things you can do with wdired:
+;; Another things you can do with WDired:
;;
;; - To move files to another directory (by typing their path,
;; absolute or relative, as a part of the new filename).
;;
;; - To change the permission bits of the filenames (in systems with a
;; working unix-alike `dired-chmod-program'). See and customize the
-;; variable `wdired-allow-to-change-permissions'. To change a single
+;; variable `wdired-allow-to-change-permissions'. To change a single
;; char (toggling between its two more usual values) you can press
-;; the space bar over it or left-click the mouse. To set any char to
+;; the space bar over it or left-click the mouse. To set any char to
;; an specific value (this includes the SUID, SGID and STI bits) you
-;; can use the key labeled as the letter you want. Please note that
+;; can use the key labeled as the letter you want. Please note that
;; permissions of the links cannot be changed in that way, because
;; the change would affect to their targets, and this would not be
;; WYSIWYG :-).
;;
;; - To mark files for deletion, by deleting their whole filename.

;;; Installation:
;; (require 'wdired)
;; (define-key dired-mode-map "r" 'wdired-change-to-wdired-mode)
;;
-;; This is recommended way for faster emacs startup time and lower
-;; memory consumption, but remind to add these lines before dired.el
-;; gets loaded (i.e., near the beginning of your .emacs file):
+;; This is the recommended way for faster Emacs startup time and lower
+;; memory consumption:

;; (autoload 'wdired-change-to-wdired-mode "wdired")

+;; (eval-after-load "dired"
;; '(lambda ()
;; (define-key dired-mode-map "r" 'wdired-change-to-wdired-mode)

-;; the default behavior.
+;; Type "M-x customize-group RET wdired" if you want to make changes
+;; to the default behavior.
;;; Usage:
;;; Change Log:
-;; From 1.9 to 1.91
-;;
-;; - Fixed a bug (introduced in 1.9) so now files can be marked for
-;; deletion again, by deleting their whole filename.
-
-;; From 1.8 to 1.9
-;;
-;; - Another alternative way of editing permissions allowed, see
-;; `wdired-allow-to-change-permissions' for details.
-;;
-;; - Now wdired doesn`t relies in regexp so much. As a consequence of
-;; this, you can add newlines to filenames and symlinks targets
-;; (although this is not very usual, IMHO). Please note that dired
-;; (at least in Emacs 21.1 and previous) does not work very well
-;; with filenames with newlines in them, so RET is deactivated in
-;; wdired mode. But you can activate it if you want.
-;;
-;; - Now `upcase-word' `capitalize-word' and `downcase-word' are not
-;; advised to work better with wdired mode, but the keys binded to
-;; them use wdired versions of that commands.
-;;
-;; - Now "undo" actions are not inherited from wdired mode when
-;; changing to dired mode.
-;;
-;; - Code and documentation cleanups.
-;;
-;; - Fixed a bug that was making wdired to fail on users with
-;; `dired-backup-overwrite' set to t.
-;;
-;; - C-c C-[ now abort changes.
-
-;; From 1.7 to 1.8
-;;
-;; - Now permission (access-control) bits of the files can be changed.
-;; Please see the commentary section and the custom variable
-;; `wdired-allow-to-change-permissions' for details.
-;;
-;; - Added another possible value for the variable
-;; `wdired-always-move-to-filename-beginning', useful to change
-;; permission bits of several files without the cursor jumping to
-;; filenames when changing lines.
-
-;; From 0.1 to 1.7
-
-;; - I've moved the list of changes to another file, because it was
-;; huge. Ask me for it or search older versions in google.
-
-;;; TODO:
-
-;; - Make it to work in XEmacs. Any volunteer?
+;; Google is your friend (previous versions with complete changelogs
