 ;;; Commentary:
 
-;; This package allows the entire contents (or as much as possible) of the
-;; minibuffer to be visible at once when typing.  As the end of a line is
-;; reached, the minibuffer will resize itself.  When the user is done
-;; typing, the minibuffer will return to its original size.
-
-;; In window systems where it is possible to have a frame in which the
-;; minibuffer is the only window, the frame itself can be resized.  In
-;; Emacs 19.22 and earlier, the frame may not be properly returned to
-;; its original size after it ceases to be active because
-;; `minibuffer-exit-hook' didn't exist until version 19.23.
-;;
-;; Prior to Emacs 19.26, minibuffer-exit-hook wasn't called after exiting
-;; from the minibuffer by hitting the quit char.  That meant that the
-;; frame size restoration function wasn't being called in that case.  In
-;; 19.26 or later, minibuffer-exit-hook should be called anyway.
-
-;; Note that the minibuffer and echo area are not the same!  They simply
-;; happen to occupy roughly the same place on the frame.  Messages put in
-;; the echo area will not cause any resizing by this package.
-
-;; This package is considered a minor mode but it doesn't put anything in
-;; minor-mode-alist because this mode is specific to the minibuffer, which
-;; has no mode line.
-
-;; To enable or disable this mode, use M-x resize-minibuffer-mode.
+;; This package is obsolete.  Emacs now resizes mini-windows
+;; automatically.
