Thanks - this looks promising.

But I now have another problem: The result of tangling from a code block
is different then when calling interactively.

Consider the following org file:

--8<---------------cut here---------------start------------->8---
#+PROPERTY: header-args :tangle no

* DESCRIPTION File
:PROPERTIES:
:header-args+: :tangle ./DESCRIPTION
:END:

#+begin_src RDescr
test
#+end_src

* And the tangling
#+BEGIN_SRC emacs-lisp :results value
(mapconcat (lambda (x) (file-relative-name x "..")) (org-babel-tangle) "\n")
#+END_SRC

#+RESULTS:

--8<---------------cut here---------------end--------------->8---

When tangling interactively, the file DESCRIPTION is tangled properly.
But when I call (org-babel-tangle) from the code block, nothing is
tangled because in this case, the property =tangle= is equal to =no=
based on the file wide property setting in the beginning.

Is this a bug or is it simply not possible to tangle from a code block?

Thanks,

Rainer
