+  // ---------------------------
+  //
+  // There are two ways to use Connect(): blocking and non-blocking,
+  // depending on the value passed as the 'wait' (2nd) parameter.
+  //
+  // Connect(addr, true) will wait until the connection completes,
+  // returning true on success and false on failure. This call blocks
+  // the GUI (this might be changed in future releases to honour the
+  // wxSOCKET_BLOCK flag).
+  //
+  // Connect(addr, false) will issue a nonblocking connection request
+  // and return immediately. If the return value is true, then the
+  // connection has been already successfully established. If it is
+  // false, you must wait for the request to complete, either with
+  // WaitOnConnect() or by watching wxSOCKET_CONNECTION / LOST
+  // events (please read the documentation).
+  //
+  // WaitOnConnect() itself never blocks the GUI (this might change
+  // in the future to honour the wxSOCKET_BLOCK flag). This call will
+  // return false on timeout, or true if the connection request
+  // completes, which in turn might mean:
+  //
+  //   a) That the connection was successfully established
+  //   b) That the connection request failed (for example, because
+  //      it was refused by the peer.
+  //
+  // Use IsConnected() to distinguish between these two.
+  //
+  // So, in a brief, you should do one of the following things:
+  //
+  // For blocking Connect:
+  //
+  //   bool success = client->Connect(addr, true);
+  //
+  // For nonblocking Connect:
+  //
+  //   client->Connect(addr, false);
+  //
+  //   bool waitmore = true;
+  //   while (! client->WaitOnConnect(seconds, millis) && waitmore )
+  //   {
+  //     // possibly give some feedback to the user,
