Yes, the name is mactex2ooo.lisp for a reason ;)
Some functions are changed a little bit, too, but you are right, this is
more or less a work around.

Sorry. As I said, I am a very beginner of Lisp. I just had to restart
reading PAIP (p. 137 -> 50 ;/), because of a lack of time for learning
it continuously. On the other hand, I just needed this export-function.
There had been too many functions/macros/... which I did not know about
and asking via this mailing list took too much time (and could not be
effective due to my lack of Lisp-knowledge).
But I am keen on learning Lisp and maybe some day I can contribute to
maxima.

Yes, Norvig is talking about data-reusing and data-driven programming ;)
By the way, chapter 8 "Symbolic Mathematics: A Simplification Program",
paragraph 9.6 "A Case Study in Efficiency: The Simplify Program" and
chapter 15 "Symbolic Mathematics with Canonical Forms" will connect to
Maxima again.

I do not know how fast this will be done, but even if I will not be able
to help - I can watch and learn.

Yes, sure. Maybe I can do export-improvements in your file, instead of
mactex2ooo then - and send them to you, because ooo() is only tested
with the formulas /I/ use so far.
