Martin,
I took a look at the tex4ht package. Maybe I should tell you
what my "agenda" is.
I am motivated to make mathematical content and functionality
as easy as possible to access on the web.
To me the only possibility for doing this is by using a web
browser as the interface.
Philosophically any software I use must be Free in the sense
of Richard M. Stallman.
I want a potential user to be able to navigate to a URL in their
browser and be exposed to full mathematical content and
functionality. To be as easy as possible the user should not
have to download or install any other packages or plugins.
This means using only native browser capability. I think I
have demonstrated that this is possible although of course
much work remains to be done.
The tex4ht package looks like it's too hard to install. I don't
run a debian based system. The only way tex4ht would fit
with my plan is if it was bundled and configured with axiom.
I am not against other approaches. The more the merrier.
But for now I am only interested in the above.
