and must be freed with
.Xr lowdown_odt_free 3 .
.Pp
The bits recognised in
.Fa opts->oflags
are
.Dv LOWDOWN_ODT_SKIP_HTML
and
.Dv LOWDOWN_STANDALONE .

.Sh EXAMPLES
The following parses
.Va b

.Va bsz
and outputs in
.Dq flat
OpenDocument format.
.Bd -literal -offset indent
struct lowdown_buf *out;

struct lowdown_node *n;
void *rndr;

if ((doc = lowdown_doc_new(NULL)) == NULL)

if ((n = lowdown_doc_parse(doc, NULL, b, bsz, NULL)) == NULL)
	err(1, NULL);
if ((out = lowdown_buf_new(256)) == NULL)
	err(1, NULL);
if ((rndr = lowdown_odt_new(NULL)) == NULL)
	err(1, NULL);
