If you use dependency on Shared in your mod (which is by default, unless you changed meta yourself) you already have __Start goal from Shared, which contains it, and it will be executed when it's needed.
Ah, of course! Didnt realize it was for a mod with Shared dependency, blame my apparently poor reading comprehension :S.
I was thinking in a __Start builded from scratch effectively changing Meta.lsx like you said. From practicing with the classic editor, I find is easy to me that way, building, collecting or unpacking one goal at the time. Maybe I should "modernize" my working plan :P
Thanks!
