[appfuse-user] generated dependencies in POM

[dev dev]

I'm using Spring MVC modular version 2.0. Afte running mvn
appfuse:full-source, core and web directories got created. then cd to web
directory and view the pom.xml, the core dependency is definded as follows:

<dependency>
            <groupId>${pom.parent.groupId}</groupId>
            <artifactId>${pom.parent.artifactId}-core</artifactId>
            <version>${pom.parent.version}</version>
        </dependency>

How does this property ${pom.parent.groupId} get populated?

Thanks
