What you need for this book

If you are reading this book, we assume you have installed Julia and written a few simple Julia programs and that you are familiar with Julia REPL. The basic Julia installation, available from http://julialang.org/downloads, is the only prerequisite for this book. We will demonstrate most of the techniques in the book using REPL, and we encourage your to follow along. Paste the commands on to REPL and inspect the output yourself.
