The second article is probably the least interesting one. It covers interoperating between Python and C++. Just basic stuff that you can probably get from the boost::python tutorial in the boost documentation. I'm actually not even sure I should even bother writing it, except that thats the part that sets up the code necessary for the third article, which is about using Python to do cool things like embed an interactive interpreter in an application.
In any case, part one is done now. Comments as usual are appreciated. I'm going to try to get all three done before I ship it off though.
