I'm glad I don't have to do that. MathML is scary (and I mean that as a 
programmer, not as an author; all those attributes and stuff) ...

(Wow! Googling for pmml2tex finds that page *only*.)

I'm a bit curious, though: The goals for pmml2tex is stated as 
"rendering via conversion via OpenMath to Presentation mathml and TeX".

Having dabbled a bit with implementing OpenMath->LaTeX conversion 
myself last year (on the reasoning that it'll be faster in the long run 
than hand-converting a large collection of computer-derived formulae; 
in order to write a paper reporting the results, they somehow need to 
be turned into LaTeX), I did consider going via MathML, but eventually 
decided not to; MathML felt too messy to be a convenient intermediate 
format. (Still, I'll probably also want to do OM->PMML at some point in 
the future.) So is PMML in your mind an optimal intermediate when going 
OM->TeX, or is it more that you get it for free from composing OM->PMML 
and PMML->TeX conversions?

(I should perhaps add that I considered sensible formatting of the 
generated LaTeX code to be important; since it's going into a document 
that I'll do editing of, I don't want it to be a compact block of 
commands without any hint of the logical structure of the formula.)
