Ruby Meets Cocoa

The document discusses RubyCocoa, which bridges the Ruby and Objective-C programming languages allowing Ruby code to access Cocoa frameworks, describes its history and key contributors, and provides an example of how RubyCocoa allows Ruby code to call methods on Objective-C classes similarly to how it is done in Objective-C. It also lists additional resources for learning more about RubyCocoa, Cocoa, and Objective-C.
