Simple outlining

[Yang]

Hi, are there any outlining tools for Emacs that support the following
type of outline editing?

- plugin will auto-insert bullets when i
 manually break a line
- plugin will auto-hanging-indent when
 the text wraps (and preferably
 maintain filled lines as I edit)
   - hitting tab (or something) will
     indent the outline
   - hitting shift-tab will de-indent
     the outline (instead of needing
     to manually delete the correct
     amount)

I've looked at Outline and Allout but they don't quite provide this. I
tried asking in #emacs but the folks there said they didn't know of
such a tool (I'd be surprised if it doesn't exist). Thanks in advance.
