;;; 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 categorise and tag
;; your images, use image-dired.el
;;
;; The 'convert' program from 'ImageMagick'
;; [URL:http://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.

;; 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.
