+DESCRIPTION
+-----------
+The zone append command writes the logical blocks specified by the command to
+the medium from the data data buffer provided. Will use stdin by default
+if you don't provide a file.
+
+On sucess, the program will report the LBA that was assigned to the data for
+the append operation.
+
+OPTIONS
+-------
+-n <NUM>::
+--namespace-id=<NUM>::
+	Use the provided namespace id for the command. If not provided, the

+	to a non-block device, the parameter is required.
+
+-s <IONUM>::
+--zslba=<IONUM>::
+
+-z <IONUM>::
+--data-size=<IONUM>::
+	Size of data, in bytes.
+
+-y <IONUM>::
+--metadata-size=<IONUM>::
+	Size of metadata in bytes.
+
+-d <FILE>::
+--data=<FILE>::
+	Data file providing the data to write. If none provided, contents are
+	sent from STDIN.
+
+-M <FILE>::
+--metadata=<FILE>::
+	Metadata file, if necessary.
+
+-l::
+--limited-retry::
+	Sets the limited retry flag.
