I put the "Simple Literate Programming Example" from the Org-Babel
Introduction in a file hello.org, namely,
==================hello.org===========================
#+srcname: hello-world-prefix
#+begin_src sh :exports none
echo "/-----------------------------------------------------------\\"
#+end_src
#+srcname: hello-world-postfix
#+begin_src sh :exports none
echo "\-----------------------------------------------------------/"
#+end_src
#+srcname: hello-world
#+begin_src sh :tangle hello :exports none
# <<hello-world-prefix>>
echo "| hello world |"
# <<hello-world-postfix>>
#+end_src
==================end=hello.org===========================
Then I do "M-x org-babel-tangle", and this generates the file hello:
=================begin=hello============================
#!/usr/bin/env sh
# [[file:~/ORG/hello.org][hello-world]]
# <<hello-world-prefix>>
echo "| hello world |"
# <<hello-world-postfix>>
# hello-world ends here
==================end=hello=============================
which does not seem to jive with the Introduction, which, among other
things, says the <<*>>'s should expand. I've seen other examples
where the #'s are removed from before the <<*>>'s, but this does not
seem to matter. Any ideas on what I'm missing? My .emacs file is
==============begin=.emacs=============================
(add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))
(global-set-key "\C-cl" 'org-store-link)
(global-set-key "\C-ca" 'org-agenda)
(global-set-key "\C-cb" 'org-iswitchb)
(setq load-path (cons "/tmp/org-mode/lisp" load-path))
(setq load-path (cons "/tmp/org-mode/contrib/lisp" load-path))
(require 'org-babel-init)
(require 'org-babel-sh)
(org-babel-load-library-of-babel)
=============end=.emacs=================================
and the "/tmp/org-mode/" is a Git directory from today.

Hi w t,
Thanks for pointing this out.
I believe you'll need to add the :noweb yes header argument to code
blocks that include <<>> to be expanded.
I'll update the example on Worg to reflect this newer feature of Org-
babel.
All the best,
Tom
