[metapost] [MetaFun] Source code of documentation

[TeXWorld]

Hello,

I found on pragma-ade.com at lot of interesting documents. I 
particularly read one about MetaFun and I'm very interesting in 
reproducing examples of metafun-p.pdf page 241. The problem is that I 
don't know if the sources of this document are available on Internet (I 
searched but found nothing) and I don't know how to compile them.
Can somebody give me a clue ?

Thank you very much.



Jack
