Roberto-
Shouldn't the there be a way for a new user to download OACS onto a non-Internet connected computer and still be able to learn the system (i.e. have docs be downloadable)?
I can be convinced that the docs might not belong in the main tarball, but then we need to be very clear on the download page that a complete download of OACS includes two tarballs.
I recognize no one that uses OACS today would need such instructions, but I think our audience for downloading OACS should be new users, not all the same people who already use OACS.
