+//!
+//! Instead of actually servicing sockets ourselves we require that you implement the
+//! SocketDescriptor interface and use that to receive actions which you should perform on the
+//! socket, and call into PeerManager with bytes read from the socket. The PeerManager will then
+//! call into the provided message handlers (probably a ChannelManager and NetGraphmsgHandler) with messages
+//! they should handle, and encoding/sending response messages.
