-Sitemaps
---------
-
-Sitemap files <http://sitemaps.org/> are a very nice way of telling
-search engines and other interested bots what's available on your site
-and what's changed recently. You can generate sitemap files for your
-StatusNet instance.
-
-1. Choose your sitemap URL layout. StatusNet creates a number of
-   sitemap XML files for different parts of your site. You may want to
-   put these in a sub-directory of your StatusNet directory to avoid
-   clutter. The sitemap index file tells the search engines and other
-   bots where to find all the sitemap files; it *must* be in the main
-   installation directory or higher. Both types of file must be
-   available through HTTP.
-
-2. To generate your sitemaps, run the following command on your server:
-
-   php scripts/sitemap.php -f index-file-path -d sitemap-directory -u URL-prefix-for-sitemaps
-
-   Here, index-file-path is the full path to the sitemap index file,
-   like './sitemapindex.xml'. sitemap-directory is the directory where
-   you want the sitemaps stored, like './sitemaps/' (make sure the dir
-   exists). URL-prefix-for-sitemaps is the full URL for the sitemap dir,
-   typically something like <http://example.net/mublog/sitemaps/>.
-
-You can use several methods for submitting your sitemap index to
-search engines to get your site indexed. One is to add a line like the
-following to your robots.txt file:
-
-   Sitemap: /mublog/sitemapindex.xml
-
-This is a good idea for letting *all* Web spiders know about your
-sitemap. You can also submit sitemap files to major search engines
-using their respective "Webmaster centres"; see sitemaps.org for links
-to these resources.
