 For many of the more advanced features in Maven2 it is critical that POMs be available in the local repository.
 Features like transitive dependencies and the new parent specification mechanism. The problem we run into is
 that currently we have information about a project scattered across the project.xml and the
 various properties files. What needs to be done is to encapsulate all of this in the POM.
