	2163	inserted results.
	2164
	2165	silent -- no results are inserted into the Org buffer but
	2166	the results are echoed to the minibuffer and are
	2167	ingested by Emacs (a potentially time consuming
	2168	process).
	2169
	2170	file ---- the results are interpreted as a file path, and are
	2171	inserted into the buffer using the Org file syntax.
	2172
	2173	list ---- the results are interpreted as an Org list.
	2174
	2175	raw ----- results are added directly to the Org file. This is
	2176	a good option if you code block will output Org
	2177	formatted text.
	2178
	2179	drawer -- results are added directly to the Org file as with
	2180	\"raw\", but are wrapped in a RESULTS drawer or results
	2181	macro, allowing them to later be replaced or removed
	2182	automatically.
	2183
	2184	org ----- results are added inside of a \"src_org{}\" or \"#+BEGIN_SRC
	2185	org\" block depending on whether the current source block is
	2186	inline or not. They are not comma-escaped when inserted,
	2187	but Org syntax here will be discarded when exporting the
	2188	file.
	2189
	2190	html ---- results are added inside of a #+BEGIN_EXPORT HTML block
	2191	or html export snippet depending on whether the current
	2192	source block is inline or not. This is a good option
	2193	if your code block will output html formatted text.
	2194
	2195	latex --- results are added inside of a #+BEGIN_EXPORT LATEX
	2196	block or latex export snippet depending on whether the
	2197	current source block is inline or not. This is a good
	2198	option if your code block will output latex formatted
	2199	text.
	2200
	2201	code ---- the results are extracted in the syntax of the source
	2202	code of the language being evaluated and are added
	2203	inside of a source block with the source-code language
	2204	set appropriately. Also, source block inlining is
	2205	preserved in this case. Note this relies on the
	2206	optional LANG argument.
	2207
	2208	list ---- the results are rendered as a list. This option not
	2209	allowed for inline src blocks.
	2210
	2211	table --- the results are rendered as a table. This option not
	2212	allowed for inline src blocks.
	2213
	2214	INFO may provide the values of these header arguments (in the
	2215	`header-arguments-alist' see the docstring for
	2216	`org-babel-get-src-block-info'):
	2217
	2218	:file --- the name of the file to which output should be written.
	2219
	2220	:wrap --- the effect is similar to `latex' in RESULT-PARAMS but
	2221	using the argument supplied to specify the export block
