RubyBreaker is a dynamic type documentation/checking tool for Ruby. It dynamically instruments code, monitors objects during execution, performs dynamic type checking, and generates type documentation based on the profiled information. RubyBreaker helps Ruby programs "break" out of obscurities and convolutions by auto-documenting type information.
