Hi Rainer,

First I'll give some expanded instructions in the hopes of helping out<= br> anyone else affected by my lack of good instructions in the announcement email. =A0Then I'll provide a re-write of your config below as an examp= le.

Sounds perfect.
=A0
=

Babel took the integration into Org-mode as an opportunity to do some
much needed house cleaning. =A0Most importantly we have cleared out
unnecessary configuration variables -- which is great unless you already have these variables set.

We have eliminated the two main internal lists of languages, namely
- org-babel-interpreters and
- org-babel-tangle-langs
so any config lines which mention those variables, can/should be
stripped out in their entirety. =A0This includes any calls to the
`org-babl-add-interpreter' function, whose sole purpose was to add
languages to the org-babel-interpreters variable.

=
OK - I understand that and it makes perfect sense.

alright, so with those calls stripped out, we may still in some cases
want to associate a file name extension with certain languages, for
example we want all of our emacs-lisp files to end in a ".el", we= can do
this will the `org-babel-tangle-lang-exts' variable. =A0In general you<= br> shouldn't need to touch this as it already has defaults for most common=
languages, and if a language is not present in org-babel-tangle-langs,
then babel will just use the language name, so for example a file of c
code will have a ".c" extension by default, sh code will have a &= quot;.sh"
extension ect...

Perfect.
=A0=

You also mentioned shebang lines. =A0This configuration now lives in
header arguments. =A0So the shebang for a single file can be set at the
code block level, e.g.

#+begin_src clojure :shebang #!/usr/bin/env clj
=A0(println "with a shebang line, I can be run as a script!") #+end_src

That's perfect - it adds = much flexibility, and to do it via header arguments is absolutely perfect f= or me.
=A0

note that whenever a file is tangled which includes a shebang line,
org-babel will make the file executable, so there is good reason to only

Wow - even better!
=A0
add shebangs at the source-code level. =A0However if you're sure that y= ou
want all of your code in some language (say shell scripts) to tangle out with shebang lines, then you can customize the default header arguments
for that language, e.g.

;; ensure this variable is defined defined
(unless (boundp 'org-babel-default-header-args:sh)
=A0(setq org-babel-default-header-args:sh '()))

;; add a default shebang header argument
(add-to-list 'org-babel-default-header-args:sh
=A0 =A0 =A0 =A0 =A0 =A0 '(:shebang . "#!/bin/bash"))

Good to know, but in general I am perfectly ha= ppy without shebang lines. But there are cases, where they are necessary.
=A0

The final change, is that to conform to Emacs guidelines, the prefix
org-babel-* in all require lines, has been changed to ob-*, also, since
Babel now loads by default with Org-mode you can remove any
=A0(require 'org-babel)
or
=A0(require 'org-babel-init)
that may by lying around your configuration.

OK - understood.
=A0

Whew! that was alot of writing for a /simplification/ of configuration.
=

Well - but it made many things much cleare= r for me. It is often more difficult to explain the changes which need to b= e made then to explain to a new user how it should be done.
=A0
Hopefully the example of your configuration below will be a more
succinct demonstration of the needed transformations.

the above becomes

I don= 't seem to need this line anymore - =A0it is working without. Also, I d= on't remember why I put it in...

the above can be omitted entirely

If you've made it this far, then thanks for your patience,
=

I have to thank you for the patience to write such a cl= ear description. I must say I enjoyed reading it. I would actually suggest = to put this up on the WiKi for org-babel, as it can help change ones config= uration, but also to understand how to configure the integrated org-babel -= Thanks a lot.
=A0
and please=A0let me know if y= ou run into any problems with the above.

Thanks again - it is working.

=A0Just one additional question: When I go on the menu = to Org -- Documentation -- Info Documentation, I still get the info help fr= om version 6.21b, although I installed the version from git, and under Org = -- Documentation -- Show Version it gives me "Org-mode version 6.36tra= ns (release_6.36.408.g7f21f)".

Can I change this somehow? It seems that the Info Docum= entation is the one which is part of emacs.
