+// SandboxFactory is a set of static methods to get access to the broker
+// or target services object. Only one of the two methods (GetBrokerServices,
+// GetTargetServices) will return a non-null pointer and that should be used
+// as the indication that the process is the broker or the target:
+//
+// BrokerServices* broker_services = SandboxFactory::GetBrokerServices();
+// if (NULL != broker_services) {
+//   //we are the broker, call broker api here
+//   broker_services->Init();
+// } else {
+//   TargetServices* target_services = SandboxFactory::GetTargetServices();
+//   if (NULL != target_services) {
+//    //we are the target, call target api here
+//    target_services->Init();
+//  }
+//
+// The methods in this class are expected to be called from a single thread
+//
+// The Sandbox library needs to be linked against the main executable, but
+// sometimes the API calls are issued from a DLL that loads into the exe
+// process. These factory methods then need to be called from the main
+// exe and the interface pointers then can be safely passed to the DLL where
+// the Sandbox API calls are made.
