Hi List, 

this does not work, although I would think it should (at least if there
is no typo or so):

,----
| #+name: project-root
| #+header: :var buf-file=(buffer-file-name)
| #+begin_src emacs-lisp
| (file-name-directory
|  (directory-file-name
|   (file-name-directory buf-file)))
| #+end_src
`----

#+results: project-root
: /home/tj/News/drafts/

,----
| #+name: project-name
| #+header: :exports none
| #+header: :var root-dir=project-root(buf-file=(buffer-file-name))
| #+begin_src emacs-lisp
|   (mapconcat
|    'capitalize
|    (split-string
|     (file-name-nondirectory root-dir)
|     "-" 'OMIT-NULLS)
|    " ")
| #+end_src
`----

#+results: project-name

Wrong usage of :var or limitations of header arguments?
