+class ResultSet(list):
+    """
+    The ResultSet is used to pass results back from the Amazon services
+    to the client. It is light wrapper around Python's :py:class:`list` class,
+    with some additional methods for parsing XML results from AWS. 
+    Because I don't really want any dependencies on external libraries, 
+    I'm using the standard SAX parser that comes with Python. The good news is 
+    that it's quite fast and efficient but it makes some things rather 
+    difficult.
+
+    You can pass in, as the marker_elem parameter, a list of tuples.
+    Each tuple contains a string as the first element which represents
+    the XML element that the resultset needs to be on the lookout for
+    and a Python class as the second element of the tuple. Each time the
+    specified element is found in the XML, a new instance of the class
+    will be created and popped onto the stack.
+
+    :ivar str next_token: A hash used to assist in paging through very long
+        result sets. In most cases, passing this value to certain methods
+        will give you another 'page' of results.
