Using emaxima in LaTeX



I'm trying to use emaxima.sty to typeset a document containing some maxima
sessions.  However, the file "EMaximaIntro.ps" which comes bundled with
maxima 5.10.0 seems more plain-TeX oriented.  And try as I might, I can't
get a nice colored session (with TeX-ed output), such as is shown on page 9
of that document. Does anybody have a nice LaTeX document which uses emaxima
they would be happy to share with me?

Thanks,
Alasdair
