  26
  27 ;; This file provides conversion between UCS and various
  28 ;; transliteration schemes, such as ITRANS, kyoto-harvard and aiba
  29 ;; methods.  It also provides conversion between IS 13194 and UCS.
  30 ;; Finally, this program provides the compatibility support with
  31 ;; old implementation of Devanagari script.

  35 ;;; Transliteration
  36
  37 ;; The followings provide the various transliteration schemes (such as
  38 ;; ITRANS, kyoto-harvard, and Aiba) of Indian scripts.  They are also
  39 ;; used in quail/indian.el for typing Indian script in Emacs.
