No - sorry for the misunderstanding. Charlie has already clarified that
in this thread, we're talking about code that is not yet in the Tw
repository - but will be merged once ready.

to code than that, once the measurement is implemented itself ;).

Lua is untouched (in fact, the Python code is, too, I just don't
activate it in the builds anymore).
The original point was to provide different scripting languages so
 - people can use whatever they are comfortable with
 - as much code as possible can be reused (think, e.g., of querying
citation databases)
