+# A generator that creates a sitemap.xml page for jekyll sites, suitable for submission to
+# google etc.
+#
+# To use it, simply drop this script into the _plugins directory of your Jekyll site.
+#
+# When you compile your jekyll site, this plugin will loop through the list of pages in your
+# site, and generate an entry in sitemap.xml for each one.
