* A test helper to exercise the progress display.

*
|
|
* Reads instructions from standard input, one instruction per line:
|
|
*
|
|
* "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.
|
|
*
|
|
* See 't0500-progress-display.sh' for examples.
