    This recipe adds a "fmt=count" option to (:pagelist:), to return a
    simple count of the number of pages in the list.  Examples:

    (:pagelist fmt=count:)                    # pages on the wiki
    (:pagelist group=Main fmt=count:)         # pages in group Main
    (:pagelist link={*$FullName} fmt=count:)  # links to current page
    
    To use this recipe, simply copy it into the cookbook/ directory, and
    add the following line to a local customization:

        include_once('cookbook/fplcount.php');
