This would be a *very* valuable contribution, also because
during discussions on a (private :^( ) Red Hat mailing list,
we were told that the probablilty of TeXmacs being included
into the standard distribution would significantly grow
if we had a good interface with GNU Octave.

Indeed, if you *have* a routine for (La)TeX-printing,
then you may wish to use this routine by default
if you know that Octave was called from TeXmacs.
The easiest solution would be to convince to the Octave
maintainers to support a --texmacs option and to include
the necessary code directly into Octave. If this is not possible,
then you may also write appropriate filters, like Andrey Grozin
has done for some computer algebra systems (see the TeXmacs sources).
It might be interesting for you to directly discuss some of these
issues with Andrey (grozin a t texmacs.org).

Best wishes, Joris
