Oh, excellent!  What a great way to outline your ruby code.

You can also do this in emacs ...

    M-X grep RET grep -n -RE "^ *(class|module|attr|def)"  lib RET

And you will get a grep buffer with the tagged outline.  Just middle mouse 
click on any line in the grep buffer and emacs will automatically go to that 
file and line number.  Great for browsing code.

Thanks Hal.
