The documentation is very confusing, but between reading the source code and rereading the docs, here's how it works:

• min is the starting unit, e.g. 0
• max is the ending unit, e.g. 100 or 1000
or in your case, maybe number of files or total number of Gb
• report($format, $cur) - prints out how much has been done so far using the format $format. $cur is the number of units consumed so far, i.e. the number of files or number of Gb examined so far
• time estimates are calculated by comparing the lapsed time to $cur/($max - $min) and scaling up appropriately.

So the usage would be something like:

1. create a progress object with appropriate min/max
2. in a loop,
   1. do N units of work
   2. after each N units have been completed, call report($format, $cur) to report how many units have been completed so far

BTW - I also noted the docs show report like this report(format, [current item]). I'm not quite sure what was intended by that. According to the source code, the call should look like this: report($format, $currentItem)

Best, beth
