  * Example of counting executions currently in the     *
  * repository of an Xpress Executor component in the   *
  * same solution.                                      *
  *                                                     *
  * Note: this must be run within a cloud component     *
  * (Xpress Insight or Xpress Executor), from a         *
  * solution that contains at least one Xpress Executor *
  * component.                                          *
  *                                                     *
  * This is an example of using the 'dmp' module, but   *
  * in real solutions you should use the 'executor'     *
  * module to sent requests to an Xpress Executor       *
  * component.                                          *
  *                                                     *
