+;;; Commentary:
+
+;; This package create two new mode: thumbs-mode and
+;; thumbs-view-image-mode. It is used for images browsing and viewing
+;; from within emacs. Minimal image manipulation functions are also
+;; available via external programs.
+;;
+;; The 'convert' program from 'ImageMagick'
+;; [URL:http://www.imagemagick.org/] is required.

+;; CHANGELOG
+;;
+;; 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 a image will bring you in image view mode
+;; for that image.  C-h m will give you a list of available keybinding.
