// DECLARE_SERVICE(SomeSvcCreator<YourServiceClass1>);
// DECLARE_SERVICE(SomeSvcCreator<YourServiceClass2>);
// DECLARE_SERVICE(SomeSvcCreator<YourServiceClass3>);
// DECLARE_SERVICETMULTI(svc_serviceclass, YourMultiInstanceServiceClass1>);
// DECLARE_SERVICETMULTI(svc_serviceclass, YourMultiInstanceServiceClass2>);
// DECLARE_SERVICETMULTI(svc_serviceclass, YourMultiInstanceServiceClass3>);
// DECLARE_SERVICETSINGLE(svc_serviceclass, YourSingleInstanceServiceClass1>);

// DECLARE_SERVICETSINGLE(svc_serviceclass, YourSingleInstanceServiceClass3>);
// END_SERVICES(YourClass_Svc, _YourClass_Svc);

// The macro DECLARE_MODULE_SVCMGR should be defined in your main cpp file if you are compiling
// a standalone exe without using the Application class. In this case you should also add
// MODULE_SVCMGR_ONINIT(); in your app startup and MODULE_SVCMGR_ONSHUTDOWN() in your app shutdown
// (class Application does this already)

// You can use BEGIN_SYS_SERVICES to declare a service that is initialized in priority and 
// shutdown late (normal version inits late, shutdowns early)
