Ruby is not just a programming language, but an entire philosophy about programming. It makes programming fun, productive, and rewarding. Most programs consist of code that needs to be organized into functions. And so most Ruby programs consist of classes and modules containing useful functions for interacting with the real world, operating on text, working with objects, creating GUIs, doing system administration tasks, building web applications… you name it. Ruby is at its heart a toolkit for accessing existing libraries like OpenSSL and providing something like Visual Basic style syntactic sugar to make working with them fun.
