Question on Victory Points

[Dogboy]

I'm planning to host a game for a few friends, using the Dom 3 version of the Arduria map:

(Thanks Wauthan!)

How do I set up the game to award victory by victory points?

The map has 12 land and two sea starting locations. The default victory condition is by victory points, though the text that comes with the map indicates that it is not enforced by the map file. Each start location is worth one point, five neutral provinces are worth one point each and one neutral province is worth two. That's a total of 21 if no additional points are used. I'd like to set the game up to award victory to the first player with 11 victory points. How do I do it (and how do I know it's working?)

Thanks!
