 14.8.2.25 ‘:post’
 .................
 
 The ‘:post’ header argument is used to post-process the results of a
 code block execution.  When a post argument is given, the results of the
 code block will temporarily be bound to the ‘*this*’ variable.  This
 variable may then be included in header argument forms such as those
 used in var header argument specifications allowing passing of
 results to other code blocks, or direct execution via Emacs Lisp.
 
    The following example illustrates the usage of the ‘:post’ header
 argument.
 
      #+name: attr_wrap
      #+begin_src sh :var data="" :var width="\\textwidth" :results output
        echo "#+ATTR_LATEX :width $width"
        echo "$data"
      #+end_src
 
      #+header: :file /tmp/it.png
      #+begin_src dot :post attr_wrap(width="5cm", data=*this*) :results drawer
        digraph{
                a -> b;
                b -> c;
                c -> a;
        }
      #+end_src
 
      #+RESULTS:
      :RESULTS:
      #+ATTR_LATEX :width 5cm
      [[file:/tmp/it.png]]
      :END:
