The purpose of this mapping is to define a heterogeneous set of module names. Simply a bunch of modules. This could be used to define a set of modules to launch a mass operation upon or a set of modules that must be excluded from some global process.

The accepted format is:

    <map>
      <modules>
        <module>ModuleName</module>
        <module>ModuleName2</module>
        ...
      </modules> 
    </map>

You will be able to get the set of modules using the getFullModuleSet() method.
