A template based engine heavily inspired by Java Server Pages (JSP). It actually uses the same syntax, however, the intrinsic objects accessible from within the template are EMF model objects instead of HTTP request/response objects. It can be used to generate an arbitrary code from a given EMF model, not only Java code.
