I've trying to get a handle on PyGI for a while now, but I'm still in
a bit of a fog.  I've worked on some PyGTK apps so understand that OK,
but what I'm really looking for are answers to questions like:

1. What problem is PyGI trying to solve?
2. What advantage will I see by using PyGI over PyGTK?
3. How do I port my application from PyGTK to PyGI?
