Whattttts that, ha,
But ya, one of the outcomes is tooz; but I'm not even sure there is
information being shared about the duplication that is happening
(projects seem to silo themselves with regards to stuff like this).
So I guess one of the first goals would be to undo that siloing, though
if nobody from the projects cares about doing things in the same way
using the same toolkit, then I'd say we are more screwed then I thought,
