RubyCocoa is a Mac OS X framework that allows Cocoa programming in the object-oriented scripting language Ruby. In other words, it is a bridge that let you access Objective-C objects from Ruby, and vice-versa.
Please visit the RubyCocoa Web Site http://rubycocoa.sourceforge.net/ to get more information. The http://rubycocoa.com/ Web Site also contains very interesting resources such as tutorials.
Prerequisites
Mac OS X 10.4.8 or higher.
If you overwrote Apple's Ruby with a custom version, please make sure that it has been built with --enabled-shared.
