                         that argument is a number, it specifies the number of frames to display. Otherwise all frames will be

      findjsobjects   -- List all object types and instance counts grouped by typename and sorted by instance count. Use
                         -d or --detailed to get an output grouped by type name, properties, and array length, as well as
                         more information regarding each type.
      findrefs        -- Finds all the object properties which meet the search criteria.
