1867 wrap ---- results are added directly to the Org-mode file as with

1871 org ----- similar in effect to raw, only the results are wrapped

1882 latex --- results are added inside of a #+BEGIN_LATEX block.
1883 This is a good option if you code block will output
1884 latex formatted text.
1886 code ---- the results are extracted in the syntax of the source
1887 code of the language being evaluated and are added
