I greatly appreciate your discussion of hyperdoc. I think you are
quite right to observe that open axiom is at a serious disadvantage
because of the lack of this part of the former commercial product.

Yes I think the full code for hyperdoc is (or will be) available
as open source but it has not yet been ported to use a modern
graphical user interface. That is a big job even for someone
fully familiar with gui programming.

We did have some previous discussion of this. For references

In particular see

for much of that documentation.

The pamphlet files now contain all of the spad source code (including
all comments). Editing the commentaries for xxx.spad now means editing
the associated xxx.spad.pamphlet file. The code part of these files
is automatically extracted and used during the Axiom build process.

Since the functionality of TechExplorer is not so different from
what is possible under LatexWiki, Mike's comment makes me feel
optimistic that it would be possible to implement a large part
of hyperdoc in MathAction.
