It seems that you did not try my code.  It shows something that has not been
tried so far, namely accessing the databases using SPAD, and integrating tex4ht
to get html (or mathml or whatever) output.

That was not my intention.  I said that I would put more work into it, provided
somebody would try it and succeed on MS-windows.

I did not get any feedback at all.

You know that I share this belief.  With the additional requirement that *any*
webbrowser should do.

I don't want a browser front end.  I want a working HyperDoc for MS-Windows,
that is good enough to support documentation as written for ALLPROSE.

Did my hack hang you axiom?  That would be interesting feedback, really.

Why would you care?

I did, since there is still no HyperDoc on Windows.  I thought that this might
be an easy way to help windows people.

Did you try my code?

Did you try my code?

>   how do we handle graphics?

As an aside, I should say that during my demonstration of axiom at the faculty
of maths, people were quite impressed by the quality of 3d graphics in axiom.
I don't know gnuplot, but some said that gnuplot would be quite inferiour.
Mathematica's and Maple's graphics definitively are.

no.  It should generate high quality latex.  tex4ht should generate html.  Ahm,
did you try my code, by the way?

So, what is an s-expression for a polytope?  (It is currently represented by a
file managed by polymake.  Very likely this interface will change some day.)

It seems to me that you are thinking of EXPR INT only.
