 // UDPSocket
 // Accessor API for a UDP socket in either client or server form.
 //
 // Client form:
 // In this case, we're connecting to a specific server, so the client will
 // usually use:
-//       Connect(address)    // Connect to a UDP server
-//       Read/Write          // Reads/Writes all go to a single destination
+//       Open(address_family)  // Open a socket.
+//       Connect(address)      // Connect to a UDP server
+//       Read/Write            // Reads/Writes all go to a single destination
 //
 // Server form:
 // In this case, we want to read/write to many clients which are connecting
 // to this server.  First the server 'binds' to an addres, then we read from
 // clients and write responses to them.
 // Example:
-//       Bind(address/port)  // Binds to port for reading from clients
-//       RecvFrom/SendTo     // Each read can come from a different client
-//                           // Writes need to be directed to a specific
-//                           // address.
+//       Open(address_family)  // Open a socket.
+//       Bind(address/port)    // Binds to port for reading from clients
+//       RecvFrom/SendTo       // Each read can come from a different client
+//                             // Writes need to be directed to a specific
+//                             // address.
