Just attempting to do some optimization of my code.

Does anyone know any code coverage tools that will identify any code /  
methods that are not used by my app?

Cheers

rcov is the only coverage tool I know of for Ruby. Of course it will not  
simply point to code and say “You’re not using this”, it requires  
programs that exercise the code, f.ex. tests.
