So Google released a JS library of their own. They decided to coin the library "Closure Tools"
I see the same problem rising with Google's new library. Being Google, it'll automatically gain some traction (although it might have the same competative problems as with browsers) so the name will soon be part of the list of libs. It just sounds weird to me that nobody thought of this problem. Or maybe I'm just the only who thinks this is a problem...
As for the library itself; I checked it out and.. yep. It's a library.
