+    This class can be mixed in with any L{SocketServer.TCPServer} to
+    add TLS support.
+
+    To use this class, define a new class that inherits from it and
+    some L{SocketServer.TCPServer} (with the mix-in first). Then
+    implement the handshake() method, doing some sort of server
+    handshake on the connection argument.  If the handshake method
+    returns True, the RequestHandler will be triggered.  Below is a
+    complete example of a threaded HTTPS server::
