+// -=- TcpSocket.h - base-class for TCP stream sockets.
+// This header also defines the TcpListener class, used
+// to listen for incoming socket connections over TCP
+//
+// NB: Any file descriptors created by the TcpSocket or
+// TcpListener classes are close-on-exec if the OS supports
+// it. TcpSockets initialised with a caller-supplied fd
+// are NOT set to close-on-exec.
