[Evolution] GMail & OAuth?

[Mark Stanton <mark stantoncentral co uk>]

Presumably everyone with a GMail account has just received a message
from Google that appears to say from May this year the only access to
GMail will be via OAth.

I see Evolution can do OAth, but the only documentation I can find is
about Exchange.

How do I set Evolution up for GMail? I see I can change the
authentication type to OAth. is that all that's required?
