+                                above) to support dump and restore streaming.
+                            example: users
+                        hostname:

+                                connecting to localhost.
+                            example: database.example.org

+                                Skip it if no authentication is needed.
+                            example: dbuser

+                            example: trustsome1
+                        auth_db:

+                                username has been created.
+                                If no authentication database is specified,

+                                documentation for details.

+                    List of one or more MongoDB databases to dump before

+                    database dumps are added to your source directories at
+                    runtime, backed up, and removed afterwards. Requires
+                    mongodump/mongorestore commands. See
