This is just a simple marco which creates the C++ main function of the 
program. It is just for convenience and looks more or less like this:

  int main( int argc, char **argv ) 
  {                                                           
    return Akonadi::ResourceBase::init<resourceClass>( argc, argv );
  }

The init method called here is the one which then creates the KApplication 
instance, i.e. the one I had in one of my previous postings.

So you already have the necessary parts for that.

configure is a method in AgentBase (superclass of ResourceBase) and it is 
called through D-Bus. The D-Bus code for that is in AgentBase's internals so a 
resource author like yourself just has to override the method.

The only thing the resource gets on the commandline is its identifier.
All other requests, such as configure(), are handled through D-Bus: the code 
in AgentBase registers a D-Bus object which exports methods such as 
configure() and D-Bus calls to that object then result in calls to the 
configure override in the AgentBase/ResourceBase subclass.

Not bad at all :)
