Example mwe2 Workflow for a code generator working on your own dsl

README.md

Xtend / Xtext own dsl and code generator

This is not the workflow for generating the language artifacts!

for everyone else who had managed to make a workflow to generate the language Artifacts but then always had to resort to the "runtime eclipse" for saving a slightly modified file in your dsl language only to let a generator run..
