Hello, somehow the publish with body-only feature disappeared, or I just
can't find a way to use it.

Here is my usecase:

,----
| (setq org-publish-project-alist
|       (list
|        '("foo" . (:base-directory "..."
|                   :base-extension any
|                   :publishing-directory "/tmp/"
|                   :with-section-numbers nil
|                   :body-only t <<<<<
|                   :table-of-contents nil
|                   ))))
`----

Only the bodies of the HTML files should be written to disk.  Carsten,
please consider adding this, thank you, Richard.
