;;; Commentary:
;; This is in progress ConTeXt support for AUCTeX. Please report
;; anomalies or things you believe should be added.
;; AUCTeX is closely interwoven with LaTeX. We have to split up
;; things without breaking 'em.
;; some parts are stolen from latex.el and adapted to ConTeXt.
;; TODO
;; 1. indentation still bad.
;; 2. paragraph refilling doesn't work 100%, and is very slow.
;; 4. Remove dependency on LaTeX by moving LaTeX commands to TeX.
;; 5. Most ConTeXt macro's don't currently have lisp code to query for
;; arguments. As ConTeXt arguments are quite complex, the LaTeX way
;; of querying for arguments just doesn't cut it.
;; 6. Check auto-parsing: does it detect % interface=nl for example?
;; 7. Complete adding ConTeXt macro's. Perhaps parse cont-en.xml and
;; generate the interfaces?
;; 8. Add to menu: make TeX hash (mktexlsr), context format and metapost format.
;; TODO Documentation
;; 1. multifile done differently with ConTeXt
