;;; Commentary:

;; This package analyses the text properties of the buffer and
;; converts them, along with the text, to HTML.  Mail to
;; <hniksic@xemacs.org> to discuss features and additions.  All
;; suggestions are more than welcome.

;; To use, just switch to a buffer you want HTML-ized, and type `M-x
;; htmlize-buffer'.  After that, you should find yourself in an HTML
;; buffer, which you can save.  Alternatively, `M-x htmlize-file' will
;; find a file, font-lockify the buffer, and save the HTML version,
;; all before you blink.  Even more alternatively, `M-x
;; htmlize-many-files' will prompt you for a slew of files to undergo
;; the same treatment.  `M-x htmlize-many-files-dired' will do the
;; same for the files marked by dired.

;; The code attempts to generate compliant HTML, but I can't make any
;; guarantees; I haven't yet bothered to run the generated markup
;; through a validator.  I tried to make the package elisp-compatible
;; with multiple Emacsen, specifically aiming for XEmacs 19.14+ and
;; GNU Emacs 19.34+.  Please let me know if it doesn't work on any of
;; those, and I'll try to fix it.  I relied heavily on the presence of
;; CL extensions, especially for compatibility; please don't try to
;; remove that dependency.

;; When compiling under GNU Emacs, you're likely to get oodles of
;; warnings; ignore them all.  For any of this to work, you need to
;; run Emacs under a window-system -- anything else will almost
;; certainly fail.

;; The latest version should be available at:
;;
;;        <URL:http://fly.srk.fer.hr/~hniksic/emacs/htmlize.el>

;; You can find the sample htmlize output (run on an older version of

;; TODO: Should attempt to merge faces (utilize CSS for this?).
;; Should ignore invisible text.  Should expand TABs.
