[C++-sig] extracting data from a tuple

[cramissor at aim.com]

Hi all.  Probably a newbie question here but how do you extract data 
 from a tuple using boost::python?  I've done some digging in the docs 
as well as the mailing list but have been unable to figure it out.

For example, I have the following declared in my code:

        std::map<int, tuple> widgets;

I would like to extract the third item of the tuple associated with a 
particular widget.  I have had no luck so far so any pointers would be 
much appreciated.

TIA
Marc
