Subject: unused methods

I'm wondering if there is a good, quick way to determine unused methods
in a large Ruby or Rails application.  My situation is that I wrote a
Rails app sometime last year, when I was first learning both Ruby and
Rails, and coming back to it now, it looks like a PHP app that just
happens to be written in Ruby (I came from PHP).  So, I'm refactoring a
lot of things to make it more modular and Ruby-esque, but I haven't
been deleting functionality along the way out of concern for keeping it
working while I update it.  Now, though, I would like to be able to
have something parse my source and, for every method defined, have a
count of how many times it is used, where it is called, etc.  Is there
a tool like this out there, or will I need to write such a beast?
Thanks!
