Throughout this book, commands that can be used at the command prompt will be given. This is because using a command prompt such as this is a standard technique in operating systems such as Linux and OS X. For example, in 7 we ll look at installing extra features (libraries) for Ruby, and the command prompt will be used for this. Therefore, it s necessary for you to know how to access it and run programs. If you type irb at this prompt and press Enter, you should see something like the following:
To use the storyboard formatter, copy the BBP Storyboard Formatter Basic.potx le from the companion CD to a folder on your local computer.

Unlike Windows, most modern Apple machines running Mac OS X come with a version of Ruby already installed, which means you can get started straight away. Mac OS X Panther (10.3.x) comes with Ruby 1.8.2 by default, and OS X Tiger (10.4.x) comes with Ruby 1.8.4.
Note It s likely that OS X Leopard, due to be released in 2007, will come with the latest version of Ruby,
so if you re running that operating system, unavailable at the time of writing, you might already be set to go!
Most of the code in this book works fine with Ruby 1.8.2 or higher, so if you re running Mac OS X Panther or Tiger, you don t need to do anything special. To find out which version of OS X you re running, click the Apple menu at the top left of your screen and select About This Mac. If the version of OS X is later than 10.3, you should have Ruby installed already.

If you re using OS X Tiger (10.4.x), use Apple s Software Update to upgrade to the latest version of Tip
OS X, as Apple improved Ruby distribution included in OS X from version 10.4.6 onward. Without this upgrade, you might need to reinstall Ruby manually to get some extensions, such as Ruby on Rails, to work correctly. Although this isn t a concern for the first two sections of this book, it could cause you some confusion later on.
