Very nice, are you aware of the option to split header arguments among
multiple lines?

the above could be written as...

#+headers:  :file test.png :fit yes
#+headers: :imagemagick yes :iminoptions -density 600 :imoutoptions -geometry 400
#+headers: :results (if (and (boundp 'backend) (eq backend 'latex)) "latex" "file")
#+begin_src latex :exports results :noweb yes :headers '("\\usepackage{tikz}")
  \begin{tikzpicture}
    \node[red!50!black] (a) {A};
    \node (b) [right of=a] {B};
    \draw[->] (a) -- (b);
  \end{tikzpicture}
#+end_src

which is (possibly) easier to write/read

Best -- Eric
