#+Title: Example

Results in heading [[#first]] are generated by un-exported code blocks in
heading [[#second]].

* first
  :CUSTOM_ID: first

Things my adviser cares about.

#+RESULTS: foo
: like some result: 3

* second                                                           :noexport:
  :CUSTOM_ID: second

Things my adviser does not care about, but which I need to keep, like
minutiae of generating the result.

#+Name: bar
- foo
- bar
- baz

#+Name: foo
#+begin_src sh :var bar=bar
  echo "like some result: $(echo $bar|wc -w)"
