  26 ;;; Commentary:
  27 ;; This lisp code is a general framework for translating various
  28 ;; representations of the same data.
  29 ;; among other things it can be used to translate TeX, HTML, and compressed
  30 ;; files to ISO 8859-1.  It can also be used to translate different charsets
  31 ;; such as IBM PC, Macintosh or HP Roman8.
  32 ;; Note that many translations use the GNU recode tool to do the actual
  33 ;; conversion.  So you might want to install that tool to get the full
  34 ;; benefit of iso-cvt.el
  35
  36 ; TO DO:
  37 ; Cover more cases for translation.  (There is an infinite number of ways to
  38 ; represent accented characters in TeX)
  39
  40 ;; SEE ALSO:
  41 ; If you are interested in questions related to using the ISO 8859-1
  42 ; characters set (configuring emacs, Unix, etc. to use ISO), then you
  43 ; can get the ISO 8859-1 FAQ via anonymous ftp from
  44 ; ftp.vlsivie.tuwien.ac.at in /pub/8bit/FAQ-ISO-8859-1
