+
+This script generated a google sitemap, either automaticly  or as action=sitemap or both.
+
+The automtic version creates a .gz file and is more efficient compared to the action version.
+
+google requires that the generated file is located in the root of your pmwiki installation, typically the same place as your pmwiki.php or equivalent file. Thus:
+
+http://www.brambring.nl/pmwiki.php -> sitemap must be in: http://www.brambring.nl/sitemap.xml.gz
+    
+place the file in the cookbook or local directory 
+and include the file from your farmconfig.php or config.php
+include_once("$FarmD/cookbook/sitemap.php");
+
+
+Then add the URL to your sitemap in the google webform or ping google
+
+automatic google ping is not implemented yet.
