by why the lucky stiff
This is just a small illustrated online-only Ruby book. It won't crush you. It's light as a feather (because I haven't finished it yet--hehe). And there's a reason this book will stay light: because Ruby is simple to learn.
Ruby is an interpreted, object-oriented scripting language. This book will show how to install and get started with Ruby in your environment. It demonstrates the main features of the language syntax. The text is designed to be self contained.
