Guide to using Modello

 {{{http://modello.codehaus.org/index.html}Modello}} is a tool for generating resources from a simple model. From a
 simple model you can generate things like:

 * Java sources

 * XML serialization code for the model

 * XML deserialization code for model

 * Model documentation

 * XSD

 []

 A typical modello model looks like the following:

%{snippet|id=modello-model|url=http://svn.apache.org/repos/asf/maven/archetype/trunk/archetype-common/src/main/mdo/archetype.mdo}

 To utilize Modello you would configure the <<<maven-modello-plugin>>> something like the following where you want
 to generate the Java sources for the model, the xpp3 serialization code and the xpp3 deserialization code:
