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.
