  24 ;;; Commentary:
  25 ;; This lisp code is a general framework for translating various
  26 ;; representations of the same data.
  27 ;; among other things it can be used to translate TeX, HTML, and compressed
  28 ;; files to ISO 8859-1.  It can also be used to translate different charsets
  29 ;; such as IBM PC, Macintosh or HP Roman8.
  30 ;; Note that many translations use the GNU recode tool to do the actual
  31 ;; conversion.  So you might want to install that tool to get the full
  32 ;; benefit of iso-cvt.el
  33
  34 ; TO DO:
  35 ; Cover more cases for translation.  (There is an infinite number of ways to
  36 ; represent accented characters in TeX)
  37
  38 ;; SEE ALSO:
  39 ; If you are interested in questions related to using the ISO 8859-1
  40 ; characters set (configuring emacs, Unix, etc. to use ISO), then you
  41 ; can get the ISO 8859-1 FAQ via anonymous ftp from
