rst for library doc

Hi,
I'm still looking for "the best" way to build a documentation of the
procedure program I use.

I'm very inrested in .rst. Because of the way to produce HTML and .pdf
output.
But I still need a way to built docs, by more people. so I need (I think) a
wiki as a container of that doc.

Can someone sudgest me a way?

TIA

Renato
