   1 /*
   2  * A test helper to exercise the progress display.
   3  *
   4  * Reads instructions from standard input, one instruction per line:
   5  *
   6  *   "progress <items>" - Call display_progress() with the given item count
   7  *                        as parameter.
   8  *   "throughput <bytes> <millis> - Call display_throughput() with the given
   9  *                                  byte count as parameter.  The 'millis'
  10  *                                  specify the time elapsed since the
  11  *                                  start_progress() call.
  12  *   "update" - Set the 'progress_update' flag.
  13  *
  14  * See 't0500-progress-display.sh' for examples.
