Hi John,

There has been some churn in results handling in the last year, in part
this is related to the new exporter.  I think the following is the
current best approach.

    #+begin_src sh :results output wrap
    cat <<EOF
    [[./plots/filename1.pdf]]

    [[./plots/filename2.pdf]]

    [[./plots/filename3.pdf]]
    EOF
    #+end_src

    #+RESULTS:
    :RESULTS:
    [[./plots/filename1.pdf]]

    [[./plots/filename2.pdf]]

    [[./plots/filename3.pdf]]
    :END:

I do feel bad that we had to add yet another results type (i.e. "wrap"),
but as I recall there were very good reasons for this decision and it
has made things cleaner on the implementation side.

Cheers,
