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

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 typ开发者_运维问答e 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)))

So I wanted to just print a tree quickly and all Emacs based solutions seemed either rather old or massive like (ECB/CEDET) which I don't know enough about, so for quick fix I did

sudo apt-get install tree

then from dired buffer

M-! tree --dirsfirst RET

voilà! directory tree without any specific libs, as an added bonus using tree -f outputs tree with full paths, making it obvious to jump to file with C-x C-f directly from the tree output buffer.

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

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.

I'd recommend NeoTree. It's easy to install and easy to use.
