(in-package :maxima)

;; wxMaxima xml format (based on David Drysdale MathML printing)
;; Andrej Vodopivec, 2004-2014

;; MathML-printing
;; Created by David Drysdale (DMD), December 2002/January 2003
;;
;; closely based on the original TeX conversion code in mactex.lisp,
;; for which the following credits apply:
;;   (c) copyright 1987, Richard J. Fateman
;;   small corrections and additions: Andrey Grozin, 2001
;;   additional additions: Judah Milgram (JM), September 2001
;;   additional corrections: Barton Willis (BLW), October 2001

;; Method:

;; Producing wxxml from a maxima internal expression is done by
;; a reversal of the parsing process.  Fundamentally, a
;; traversal of the expression tree is produced by the program,
;; with appropriate substitutions and recognition of the
;; infix / prefix / postfix / matchfix relations on symbols. Various
;; changes are made to this so that MathML will like the results.
