I don't know how it works with Maven as I still do everything with
ant.  In ant, add a nested <config> attribute that conforms to a
<vppconfig> element definition.  You can either put in a static value
(property), or you can instantiate any POJO (tool).

This page talks about the config element and gives some simple
examples at the bottom.

Since Veogen is based on velocity, the Veogen project might benefit
from the same technique if it doesn't yet support adding arbitrary
properties and tools to a context.
