after you *read* the page, yes, you can see that that's what it

first hit:
https://www.google.ca/search?q=fedoraproject+wiki+control+groups&ie=utf-8&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&channel=sb&gfe_rd=ctrl&ei=Z48dU46BK8rH8gaHsIHoAg&gws_rd=cr
if something is that out of date, it's kind of inappropriate to be
sucking up all the google oxygen in the room, don't you think?
