We should also look at matplotlib to see what it is doing.  I met John
Hunter (the original author of matplotlib) yesterday and he noted that
they are parsing simple LaTeX themselves but allow the option of
passing text to an external latex processor.  They are also using the
actual layout algorithms of TeX when they do the parsing and layout
without the real TeX processor.  The parser is written in Python and I
think the layout code is too, so this might require some adaptation
unless we would want to require Python to run Octave...
