Collect all `require`d Lua modules and paste them together wrapping 
every module file in

    local _ENV = _ENV -- every module needs it's own _ENV upvalue
    package.preload[ "module1" ] = function( ... )
      _ENV = _ENV -- _ENV upvalue must be the first upvalue

      --
      -- contents of file `module1.lua` inserted here
      --

    end

Finally, strip the shebang line of your main script, paste it at the 
end, and feed the whole thing to `luac`.

... or you could use squish[1], or LOOP[2] (both Lua 5.1 only, I think).
