Ruby is a cross-platform interpreted language which has many features in common with other 'scripting' languages such as Perl and Python. However, its version of object orientation is more thorough than those languages and, in many respects, it has more in common with the great-granddaddy of 'pure' OOP languages, Smalltalk. This book is a step-by-step tutorial to programming in Ruby and you can follow it chapter by chapter, reading the text and running the sample programs.
