+ * RSD action class
+ *
+ * Really Simple Discovery (RSD) is a simple (to a fault, maybe)
+ * discovery tool for blog APIs.
+ *
+ * http://tales.phrasewise.com/rfc/rsd
+ *
+ * Anil Dash suggested that RSD be used for services that implement
+ * the Twitter API:
+ *
+ * http://dashes.com/anil/2009/12/the-twitter-api-is-finished.html
+ *
+ * It's in use now for WordPress.com blogs:
+ *
+ * http://matt.wordpress.com/xmlrpc.php?rsd
+ *
+ * I (evan@status.net) have tried to stay faithful to the premise of
+ * RSD, while adding information useful to StatusNet client developers.
+ * In particular:
+ *
+ * - There is a link from each user's profile page to their personal
+ *   RSD feed. A personal rsd.xml includes a 'blogID' element that is
+ *   their username.
+ * - There is a link from the public root to '/rsd.xml', a public RSD
+ *   feed. It's identical to the personal rsd except it doesn't include
+ *   a blogId.
+ * - I've added a setting to the API to indicate that OAuth support is
+ *   available.

-    Usage Note:  

-    -----------

-    Do not use both ajaxSubmit and ajaxForm on the same form.  These

-    functions are intended to be exclusive.  Use ajaxSubmit if you want

-    to bind your own submit handler to the form.  For example,

-

-    $(document).ready(function() {

-        $('#myForm').bind('submit', function() {

-            $(this).ajaxSubmit({

-                target: '#output'

-            });

-            return false; // <-- important!

-        });

-    });

-

-    Use ajaxForm when you want the plugin to manage all the event binding

-    for you.  For example,

-

-    $(document).ready(function() {

-        $('#myForm').ajaxForm({

-            target: '#output'

-        });

-    });

-        

-    When using ajaxForm, the ajaxSubmit function will be invoked for you

-    at the appropriate time.
