At the present time this will only work on the Linux version
of Axiom.

You only really need the source of tm_axiom.c

See below.

Yes. Make sure the new binary replaces the existing one.

This is not necessary.

See http://wiki.axiom-developer.org/TeXmacs for mor information.

As far as I know, no one has done this. Certainly it is technically
possible, though perhaps a little difficult because of the way
Axiom uses another process to render graphics. This external graphics
processor can be told to save the result in a postscript format
file, then it can be imported by TeXmacs or sent via a stream
to TeXmacs from the tm_axiom interface program.

If you are motivated to work on implementing a solution to this,
I would be glad to help.

Thanks for asking :) If you can think of a way of updating the
web page at

http://wiki.axiom-developer.org/TeXmacs

so that this issue is more clearly documented, I would be very
happy if you (or anyone else) could improve the content. (This
web site is an Axiom community wiki - editable website.)
