I've made some changes (fixes?) to maxima-mode; in particular there is
a new (improved?) indentation engine. At any rate, it's been
rewritten so that it should be easy to fix any mistakes in it.
Also, preview-latex will preview EMaxima cells (in GNU Emacs), and
there is a command maxima-minibuffer, which take commands (and return
results) for Maxima in the minibuffer. A copy is at
ftp://vh213601.truman.edu/pub/Maxima/Maxima-mode.tar.gz
(If there are no problems with it and no objections, I'll put it in
CVS after the freeze.)
