+;;; Commentary:
+;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
+;; I have made some changes to make it work for Emacs 22. A lot of
+;; small bug fixes related to the format of text and overlay
+;; properties (which might have changed since the beginning of 2003
+;; when this file was originally written).
+;;
+;; The function `hfy-face-at' currently carries much of the burden of
+;; my lacking understanding of the formats mentioned above and should
+;; need some knowledgeable help.
+;;
+;; Another thing that maybe could be fixed is that overlay background
+;; colors which are now only seen where there is text (in the XHTML
+;; output). A bit of CSS tweaking is necessary there.
+;;
+;; The face 'default has a value :background "SystemWindow" for the
+;; background color. There is no explicit notion that this should be
+;; considered transparent, but I have assumed that it could be handled
+;; like if it was here. (I am unsure that background and foreground
+;; priorities are handled ok, but it looks ok in my tests now.)

+
+;; Here's some elisp code to html-pretty-print an Emacs buffer, preserving
+;; the Emacs syntax/whatever highlighting. It also knows how to drive etags
+;; (exuberant-ctags or Emacs etags) and hyperlink the code according
+;; to its (etags') output.
+
+;; NOTE: Currently the hyperlinking code only knows how to drive GNU find
+;; and the exuberant and GNU variants of etags : I do not know of any other
+;; etags variants, but mechanisms have been provided to allow htmlfontify
+;; to be taught how to drive them. As long as your version of find has
+;; the -path test and is reasonably sane, you should be fine.
+
+;; A sample of the htmlfontified / hyperlinked output of this module can be
+;; found at http://rtfm.etla.org/sql/dbishell/src/ - it's not perfect, but
+;; it's a hell of a lot faster and more thorough than I could hope to be
+;; doing this by hand.
