+/**
+ * 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.

+	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.
