> The rumen command line creates job traces from job history logs.  These job traces are read by the rumen runtime system at the behest of other applications.  We should add a command line tool to rumen to manipulate a job trace in various ways to modify a workload:
> * overlap job trace segments to increase the workload
> * extract a short segment from a long job trace
> * stretch out job traces to dilute the workload
