For the record here is the output on my Emacs:

GNU Emacs 23.2.1 (i486-pc-linux-gnu, GTK+ Version 2.20.1) of 2013-01-08
on murphy, modified by Debian

| org-mode is an interactive compiled Lisp function in `org.el'.
| 
| (org-mode)
| 
| Outline-based notes management and organizer, alias
| "Carsten's outline-mode for keeping track of everything."
| 
| Org-mode develops organizational tasks around a NOTES file which
| contains information about projects as plain text.  Org-mode is
| implemented on top of outline-mode, which is ideal to keep the content
| of large files well structured.  It supports ToDo items, deadlines and
| time stamps, which magically appear in the diary listing of the Emacs
| calendar.  Tables are easily created with a built-in table editor.
| Plain text URL-like links connect to websites, emails (VM), Usenet
| messages (Gnus), BBDB entries, and any files related to the project.
| For printing and sharing of notes, an Org-mode file (or a part of it)
| can be exported as a structured ASCII or HTML file.
