Yes there is a Chapter 0. There is a little bit of introductory stuff we need to talk about before we set you loose on Ruby. You wouldn t want to get psyched about a new gadget, get it home, and then figure out you need batteries, a grapefruit, and the ability to speak three languages to even open the box would you?

Well, plainly we need to take a good, hard look at a few things before we turn you loose.
