where to find lua and c++ examples

[DoG <g5d6@...>]

I would like to include lua into my project, which is mostly written in 
c++. I looked at luna, and it seems to be the easiest way to start off. 
I am working on a cross-platform project, but I am currently developing 
on MacOS X. So, after looking at the luna examples, and reading the 
docs and lua technotes, I still don't quite understand how to pass 
arguments to and from lua and how to handle multiple assignments. Any 
pointers?
