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