;;; Commentary:
;; This lisp code is a general framework for translating various
;; representations of the same data.
;; among other things it can be used to translate TeX, HTML, and compressed
;; files to ISO 8859-1.  It can also be used to translate different charsets
;; such as IBM PC, Macintosh or HP Roman8.
;; Note that many translations use the GNU recode tool to do the actual
;; conversion.  So you might want to install that tool to get the full
;; benefit of iso-cvt.el

; TO DO:
; Cover more cases for translation.  (There is an infinite number of ways to
; represent accented characters in TeX)

;; SEE ALSO:
; If you are interested in questions related to using the ISO 8859-1
; characters set (configuring emacs, Unix, etc. to use ISO), then you
; can get the ISO 8859-1 FAQ via anonymous ftp from
; ftp.vlsivie.tuwien.ac.at in /pub/8bit/FAQ-ISO-8859-1
