 This module makes it easy to create a RESTful data service. Simply
 by define urls and SQL statements in the apache configuration file.
 
+Example apache config
+---------------------
+Below is part of an apache configuration file. The first part loads
+the module.
+The Location directive makes the /tautoru url under control of the okioki module.
+- The OkiokiConnectionInfo shows a postgresql connect string.
+- The OkiokiCommand gives http method, a regex url (under /tautoru) and optionally decoded argument names.
+- The OkiokiSQL sets the SQL statement to execute when the command matches, it also optionally
+  allows for named SQL parameters (which are decoded from the url, query string, post parameter and cookies).
+- The OkiokiCSV sets the names (which matches the names in the select clause) of the columns to display.
