/*

* 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.
