2180 html ---- results are added inside of a #+BEGIN_EXPORT HTML block
2181 or html export snippet depending on whether the current
2182 source block is inline or not. This is a good option
2183 if your code block will output html formatted text.
2185 latex --- results are added inside of a #+BEGIN_EXPORT LATEX
2186 block or latex export snippet depending on whether the
2187 current source block is inline or not. This is a good
2188 option if your code block will output latex formatted
2191 code ---- the results are extracted in the syntax of the source
2192 code of the language being evaluated and are added
2193 inside of a source block with the source-code language
2194 set appropriately. Also, source block inlining is
2195 preserved in this case. Note this relies on the
2196 optional LANG argument.
2198 list ---- the results are rendered as a list. This option not
2199 allowed for inline src blocks.
2201 table --- the results are rendered as a table. This option not
2202 allowed for inline src blocks.
2204 INFO may provide the values of these header arguments (in the
2205 `header-arguments-alist' see the docstring for
2206 `org-babel-get-src-block-info'):
2208 :file --- the name of the file to which output should be written.
