<overview summary="In order to improve the software development industrialization, a major step consists in mass-producing software. This mass-production must be customizable, and must be able to support complex, large-scale and heterogeneous generations. Given the today's available Eclipse tools, the issue here is not to provide either a new transformation engine (model-to-model, model-to-text, text-to-model, text-to-text) or DSL (Domain-Specific Language) editor but to realize their integration for flexible software mass-production." screenshot="images/egf-screenshot-320x240.png" url="http://wiki.eclipse.org/EGF"/>
