Then really read chapter 15 of PIL: http://www.lua.org/pil/15.html
The cool thing is that the online version documents Lua 5.0, and 
module() was introduced in 5.1.

[Another change worth mentioning in 5.2: "arg" in e.g.

function myfunction (...)
   for a, b in ipairs(arg) do
     whatever(b)
   end
end

won't be defined anymore (it already behaves strangely anyway). Adding 
"arg = {...}" at the beginning does the job.]

Best,
Paul
