  23 ;;; Commentary:
  24
  25 ;; Defines a major mode for visiting image files
  26 ;; that allows conversion between viewing the text of the file
  27 ;; and viewing the file as an image.  Viewing the image
  28 ;; works by putting a `display' text-property on the
  29 ;; image data, with the image-data still present underneath; if the
  30 ;; resulting buffer file is saved to another name it will correctly save
  31 ;; the image data to the new file.
