-;;; Commentary:
-
-;; This package create two new modes: `thumbs-mode' and `thumbs-view-image-mode'.
-;; It is used for basic browsing and viewing of images from within Emacs.
-;; Minimal image manipulation functions are also available via external
-;; programs.  If you want to do more complex tasks like categorize and tag
-;; your images, use image-dired.el
-;;
-;; The 'convert' program from 'ImageMagick'
-;; [URL:https://www.imagemagick.org/] is required.
-;;
-;; Thanks: Alex Schroeder <alex@gnu.org> for maintaining the package at some
-;;         time.  The peoples at #emacs@freenode.net for numerous help.  RMS
-;;         for Emacs and the GNU project.

-;; This is version 2.0
-;;
-;; USAGE
-;;
-;; Type M-x thumbs RET DIR RET to view the directory DIR in Thumbs mode.
-;; That should be a directory containing image files.
-;; from dired, C-t m enter in thumbs-mode with all marked files
-;;             C-t a enter in thumbs-mode with all files in current-directory
-;; In thumbs-mode, pressing <return> on an image will bring you in image view
-;; mode for that image.  C-h m will give you a list of available keybinding.
