;;; Commentary:
; Calling `iso-german' will turn the net convention f or umlauts ("a etc.)
; into ISO latin umlaute for easy reading.
; hooks change TeX files to Latin-1 for editing and back to TeX sequences
; for calling TeX. An alternative is a TeX style that handles
; 8 bit ISO files (available on ftp.vlsivie.tuwien.ac.at in /pub/8bit)
; - but these files are difficult to transmit ... so while the net is
; still @ 7 bit this may be useful
; to do: translate buffer when displaying from GNUS,
; use function 'german which does the Right Thing
;
; to do: use more general regular expressions for (g)tex2iso tables, to
; cover more cases for translation.
