Note: Since MediaWiki 1.6, the MediaWiki core has a Google site map
generator... It is a
command-line utility, and it is located at
maintenance/generateSitemap.php in your MediaWiki directory. The
command line is "php generateSitemap.php sitename" and is run from the
maintenance directory at the server's command line interface. See
Manual:generateSitemap.php for more information.
