Hi Rob,

The latex printing for auto-rewrite declarations wasn't quite right - I'm
including the patches below.  Just add them to your ~/.pvs.lisp file in
your home directory (create it if it doesn't exist), and it should work.
Let me know if you have any other problems.



(defmethod pp-tex* :around ((decl auto-rewrite-decl))
  (with-slots (rewrite-names semi) decl
    (when (or (not *pretty-printing-decl-list*)
	      (not *pretty-printed-prefix*))
      (when *pretty-printing-decl-list*
	(setq *pretty-printed-prefix* t))
      (typecase decl
	(auto-rewrite-plus-decl (pp-tex-keyword 'AUTO_REWRITE+))
	(auto-rewrite-minus-decl (pp-tex-keyword 'AUTO_REWRITE-))
	(t (pp-tex-keyword 'AUTO_REWRITE)))
      (write-char #\space)
      (pprint-newline :miser))
    (pp-tex-rewrite-names rewrite-names)
    (when semi
      (write-char #\;))
    (pprint-newline :mandatory)))

(defun pp-tex-rewrite-names (names)
  (pprint-logical-block (nil names)
    (loop (pp-tex* (pprint-pop))
	  (write-char #\,)
	  (write-char #\space)
	  (pprint-newline :fill))))
