[texhax] Writing wiki documents

[Vittorio]

I would like to start a mediawiki site in order to build a manual "on 
the road" with the contributions of all my staff scattered across 
Italy. This would be really great ...
BUT I need also to print the 
manual contained in mediawiki. 

Is there any tex program or derivative 
able to convert wiki documents (which are basically php files) into a 
pdf file?

Thanks 
Vittorio
