http://[url of site]/[path to scanner]/[scanner filename].php?action=[action]
It is suggested that these files be hidden in the directory tree of the site and named something other than scanner.
scan or none - Perform a scan of the site, designed to be done in a cron job
config - set up scanner configuration
initial - perform an initial scan
If you look at scanner.php, you will find dispatch code based on the value of $_GET;['action'].
