Just to add to it: at the moment I have e.g:

#+BABEL: :var MAINVERSION=0
#+BABEL: :var SVNVERSION=(vc-working-revision (buffer-file-name))
#+BABEL: :var SVNSTATE=( symbol-name (vc-state (or (buffer-file-name)
org-current-export-file)))
#+BABEL: :var SVNSTATENUM=(if (eq (vc-state (or (buffer-file-name)
org-current-export-file)) 'up-to-date) 0 13)
#+BABEL: :var DISP_PACKAGE="seedDisp_0.4-13.tar.gz"

which would look horrible in one line and a nightmare to edit.

Any suggestions how this cold be changed?

In addition: I would like to have a warning if #+BABEL is present in the org
file, so that one remembers that it has to be changed.

Cheers,

Rainer
