Sounds interesting.

So to set the post-tangle-hook, I tried the following:

# -*- eval: (add-hook 'org-babel-post-tangle-hook( lambda ()
(call-process-shell-command "./postTangleScript.sh" nil 0 nil); -*-

But it did not work - I have no idea, what I'm missing - eval should
evaluate the following expression, which should set the post-tangle-hook.

Your suggestion, to evaluate a code block after opening, sounds very
interesting - could you give me a very short example?

Thanks, and sorry for my lack of elisp understanding - it has not improved
much...
