The progress directive is supplied by the progress plugin.
This directive generates a progress bar.
There are two possible parameter sets. The first is a single parameter "percent" which holds a percentage figure of how complete the progress bar is.
The second possible set of parameters is a pair of PageSpecs,
totalpages and donepages. The directive counts the number of
pages in each pagespec and shows the percentage of the total pages that are
done.
For example, to show what percentage of pages have discussion pages:
[[!progress totalpages="* and !*/Discussion" donepages="*/Discussion"]]
