API for maxima?



hi,
I'm interested in calling the "maxima engine" from C/C++ (or 
by any method besides the standard GUI). I looked briefly at 
the documentation and the mailing list archives, but I 
couldn't find any reference to how to do this. Is it 
possible? Maybe something like Mathematica's MathLink (or 
whatever they call it)?

Thanks for any help,
