This file does simple reference counting on pages in a PmWiki site.
Simply activate this script using
in the config.php file and then use ?action=refcount to bring up
the reference count form. The output is a table where each row
of the table contains a page name or link reference, the number
of (non-RecentChanges) pages that contain links to the page,
the number of RecentChanges pages with links to the page, and the
total number of references in all pages.
