I'm thinking about using lua to build an interpreter for my Click Tracker  
(http://code.google.com/p/clicktracker/), so it's great that this is  
working. Can you recomend any good lua tutorial? That would be a good  
resource to have in the documentation, I guess (same goes for a tcl

> those objects can have their own help patch too.
> Both pdlua and tclpd come with a lot of examples, go to the Help Browser
