              (record)              - if 'yes', record result in repository in 'experiment' standard
              (skip-record-raw)     - if 'yes', skip record raw results
              (overwrite)           - if 'yes', do not record date and time in result directory, but overwrite wa-results

              (repetitions)         - statistical repetitions (default=1), for now statistical analysis is not used (TBD)

              (share)               - if 'yes', share benchmarking results with public cknowledge.org/repo server
                                      (our crowd-benchmarking demo)
