+ * It can be used in moodle pages where config.php has been included without any further includes.
+ *
+ * It is useful for manipulating urls with long lists of params.
+ * One situation where it will be useful is a page which links to itself to perfrom various actions
+ * and / or to process form data. A moodle_url object :
+ * can be created for a page to refer to itself with all the proper get params being passed from page call to
+ * page call and methods can be used to output a url including all the params, optionally adding and overriding
+ * params and can also be used to
+ * - output the url without any get params
+ * - and output the params as hidden fields to be output within a form
+ *
+ * One important usage note is that data passed to methods out, out_action, get_query_string and
+ * hidden_params_out affect what is returned by the function and do not change the data stored in the object.
+ * This is to help with typical usage of these objects where one object is used to output urls
+ * in many places in a page.
