network-priority?

[Hans <hans.ullrich@loop.de>]

Hi folks, 

again an easy thing, I did not understand and where I did not find a clear 
answer in the web.

Question:

In network-manager I find "network-priority" set to "0". 

Is zero the highes priority or the lowest? 

Lets imagine, i have 3 wifi (wifi-1, wifi-2 and wifi-3).  
wifi-1 one should be the first, I want to connect, then wifi-2 and last 
wifi-3.

How it is to set? 

wifi-1 = 0
wifi-2 = 1
wifi-2 = 2

or 2,1,0?

Or are the numbers code for behaviour? (Here I think like numbers at files, 
where 577 = r-x,rwx,rwx)

A short answer is very ok.

Best 

Hans
