With MetaFun, it is sometimes difficult to know where MetaPost ends and where ConteXt begins ;-) At first it seemed to me that is was more of a subject for the MetaPost mailing list. 

By the way, I don't use ConTeXt and as far as I kwnow, it is precisely people who don't use ConTeXt that usually write "input mp-tool" of "input metafun" at the beginning of their MetaPost files.  Whereas ConTeXt users directly use MetaFun, I suppose. So I will be a little awkward when I ask about it in the ConTeXt mailing list :-)

Thanks again,
