What does "$>" represent in Ruby documentation?

As in:

def PP.pp(obj, out=$>, width=79)
...

This is from the pp method of the PP class:

$> is the IO destination for Kernel#print (and therefore puts), and other output methods. It defaults to $stdout, but can be changed to change the behavior of print, printf, puts, etc.
