Source Code
;; Defined in /usr/src/emacs/lisp/cedet/semantic/imenu.el.gz
;;; Which function support
;;
;; The which-function library will display the current function in the
;; mode line. It tries to do this through imenu. With a semantic parsed
;; buffer, there is a much more efficient way of doing this.
;; Advise `which-function' so that we optionally use semantic tags
;; instead, and get better stuff.
