Velocity as Code Generator...

What may seam an obvious use of Velocity is to use it as a code generator. Even 
more since Velocity templates can be file based (*.vm files), it appears to be 
a good candidate as a NetBeans module. Does anyone know if this already exists? 
Are there any open source projects that are using Velocity as a code generator 
tool for developers?
