is there an emacs tool to show a directory structure as a tree?

Question

I am aware of Speedbar (I prefer the structure in the same frame as the rest of my work), and dired shows too much information. I'm after something like the svn-status tree representation. Is there anything like that? Thank you.

EDIT: Here's what I found the most intuitive:

I am using Speedbar with the following hack from here. I had to use the commented "try this" part, FYI.

  (require 'speedbar)
  (defconst my-speedbar-buffer-name "SPEEDBAR")
  ; (defconst my-speedbar-buffer-name " SPEEDBAR") ; try this if you get "Wrong type argument: stringp, nil"
  (defun my-speedbar-no-separate-frame ()
    (interactive)
    (when (not (buffer-live-p speedbar-buffer))
      (setq speedbar-buffer (get-buffer-create my-speedbar-buffer-name)
            speedbar-frame (selected-frame)
            dframe-attached-frame (selected-frame)
            speedbar-select-frame-method 'attached
            speedbar-verbosity-level 0
            speedbar-last-selected-file nil)
      (set-buffer speedbar-buffer)
      (speedbar-mode)
      (speedbar-reconfigure-keymaps)
      (speedbar-update-contents)
      (speedbar-set-timer 1)
      (make-local-hook 'kill-buffer-hook)
      (add-hook 'kill-buffer-hook
                (lambda () (when (eq (current-buffer) speedbar-buffer)
                             (setq speedbar-frame nil
                                   dframe-attached-frame nil
                                   speedbar-buffer nil)
                             (speedbar-set-timer nil)))))
    (set-window-buffer (selected-window) 
                       (get-buffer my-speedbar-buffer-name)))

Answer 1

There is a tree extension for emacs mode Sunrise Commander. Sunrise Commander is like Midnight Commander.

Answer 2

There's the Emacs Code Browser. Last I heard using it with a current emacs may be tricky or difficult because it makes use of some tools that were recently integrated into Emacs via CEDET.
