 /**
  * Repair inconsistent nodes
  *
  * This command analyzes and repairs the node tree structure and individual nodes
  * based on the current node type configuration.
  *
  * It is possible to execute only one or more specific checks by providing the <b>--skip</b>
  * or <b>--only</b> option. See the full description of checks further below for possible check
  * identifiers.
  *
  * The following checks will be performed:
  *
  * {pluginDescriptions}
  * <b>Examples:</b>
  *
  * ./flow node:repair
  *
  * ./flow node:repair --node-type Neos.NodeTypes:Page
  *
  * ./flow node:repair --workspace user-robert --only removeOrphanNodes,removeNodesWithInvalidDimensions
  *
  * ./flow node:repair --skip removeUndefinedProperties
  *
  * @param string $nodeType Node type name, if empty update all declared node types
  * @param string $workspace Workspace name, default is 'live'
  * @param boolean $dryRun Don't do anything, but report actions
  * @param boolean $cleanup If FALSE, cleanup tasks are skipped
  * @param string $skip Skip the given check or checks (comma separated)
  * @param string $only Only execute the given check or checks (comma separated)
  * @return void
