I played with the new latex backend tonight, and made some incremental=20
improvements. texmanager now calls latex instead of tex, so we can make use=
=20
of some of the more complex layout commands, \frac{}{} for instance. A new=
=20
version of tex_demo.py is in cvs, try running:
> > python examples/tex_demo.py -dLaTeX
> > latex tex_demo.tex
> > dvips -o tex_demo.ps tex_demo.dvi
> > ggv tex_demo.ps
On a related subject, tex layout via text.usetex does not appear to be work=
ing=20
at the moment. I tried undoing my changes but was not able to get the old=20
results back. Did I break this or did I catch it in transition?

The horizontal placement appears to be fixed in CVS. I haven't gone searchi=
ng=20
for trouble in the vertical layout yet.
