 /**

  * This Mojo is an intermediate solution to generate AI configuration from a

  * given ESB project. The AI configuration is not immediately done in AI, but

  * uses a tool provided by BA. The input to that tool is is an undocumented /

  * unversioned XML format and the outcome of this plugin is created after given

  * samples. Also, the tool is NOT generic to cover all Actional use cases.

  * 

  * The generator first scans for all ESP processes in the current project,

  * creates an in-memory object graph of the objects found and runs each found

  * process though a velocity template.

  * 

  * For each process we will generate a file named svc-config-processname in a

  * subdirectory ai of our outputdirectory.
