+dump
+----
+
+The ``dump`` command uses the JSON lines format with the following message types.
+Progress, error and summary messages are only emitted when ``--target`` is specified;
+without it, the archive is streamed to ``stdout`` and any additional output would
+corrupt it.
+
+Status
+^^^^^^
+
++---------------------+--------------------------------------------------------------------+--------+
+| ``message_type``    | Always "status"                                                    | string |

++---------------------+--------------------------------------------------------------------+--------+
+
+Error

+
+These errors are printed on ``stderr``.

++-------------------+-------------------------------------------+--------+
+| ``during``        | Always "dump"                             | string |
++-------------------+-------------------------------------------+--------+
+| ``item``          | Usually, the path of the problematic file | string |

+Verbose Status
+^^^^^^^^^^^^^^
+
+Verbose status provides details about each item as it is dumped.
+Only printed if ``--verbose=2`` is specified.
+
++------------------+-----------------------------------------------+--------+
+| ``message_type`` | Always "verbose_status"                       | string |

++------------------+-----------------------------------------------+--------+
+| ``node_type``    | Either "file", "dir" or "symlink"             | string |
++------------------+-----------------------------------------------+--------+
+| ``item``         | The path of the item that was dumped          | string |
++------------------+-----------------------------------------------+--------+
+| ``size``         | Size of the item in bytes                     | uint64 |
++------------------+-----------------------------------------------+--------+
+
+Summary
+^^^^^^^
+
+Summary is the last output line of a successful dump.
