Typically, there is some syntax of type

controler.addOverridingModule(new XxxModule()) ;

Then what you can do is

1. make a local copy of RunXxxExample.java, say to MyRunXxxExample.java
2. make a local copy of XxxModule.java, say to MyXxxModule.java, 

3. replace, in MyRunXxxExample, the above overridingModule line to

   controler.addOverridingModule(new MyXxxModule());
   

4. And finally adapt MyXxxModule to your needs.

In that sense, the pre-existing {{XxxModule}} classes are default versions that typically allow configuration from the config file.  And the RunXxxExample classes are default executables around those default modules.

The most extreme case is ControlerDefaultsModule, made executable by the Controler class.
