I'm planning on using MPS to generate some part of projects but not all of it.
I'm working on several projects (SDKs) in several platforms that I want to keep in sync.
There are parts of each projects that are unique and written only once and other parts that need to be sync by all projects which I want to generate with MPS.
My question is how to reference code elements such as classes and methods of the exist code base? Should I create some kind of stub in my MPS language?
