The config is the beating heart of the Magento System. It describe, in whole, almost any module/model/class/template/etc than you'll need to access. It's a level of abstraction that most PHP developers aren't used to working with, and while it adds development time in the form of confusion and head scratching, it also allows you an unprecedented amount of flexibility as far as overriding default system behaviors go.
To start with, we're going to create a Magento module that will let us view the system config in our web browser. While this is all wrote copying and pasting, it's worth going through on your own as a way to start getting comfortable with things you'll be doing while working with Magento, as well as learning key terminology.
