finalisation if error occur

[Markus Huber <pulse@...>]

With this example the finalisation runs perfect as long as no error
occured. <file> is the main programm and if Script() ends then the
function Finalise() is called. But how can I fetch errors so that:

1. the original error is documentated in the error logs
   as good as standard behaviour (traceback)
2. Finalise() is called
   domcument errors now like Lua original
3. end


   function Finalise()
--    do something
   end


   do

      local Script,Error=loadfile(<file>)

      if Script then
         Script()
         Finalise()
      else
         io.write(Error)
      end

   end
