CFV: New Project: Skara

[Mario Torre]

Vote: Yes.

(I admit I'm *very* skeptical on the move to git, but I think it makes
sense to explore options to improve the workflow and indeed a project
is a good way to do that, I do hope the project will produce an
healthy stream of data throughout its life until we either get the JEP
mentioned or it's decided things stay the way they are - or any other
result in between).

Cheers,
Mario
