+ * A test helper to exercise the progress display.
+ *
+ * Reads instructions from standard input, one instruction per line:
+ *
+ *   "start <total>[ <title>]" - Call start_progress(title, total),
+ *                               Uses the default title of "Working hard"
+ *                               if the " <title>" is omitted.
+ *   "progress <items>" - Call display_progress() with the given item count
+ *                        as parameter.
+ *   "throughput <bytes> <millis> - Call display_throughput() with the given
+ *                                  byte count as parameter.  The 'millis'
+ *                                  specify the time elapsed since the
+ *                                  start_progress() call.
+ *   "update" - Set the 'progress_update' flag.
+ *   "stop" - Call stop_progress().
+ *
+ * See 't0500-progress-display.sh' for examples.
