Subject: class << self ...end - how does this create class methods?

I just ran into a seemingly weird problem until I discovered that the 
method that I kept trying to call as an instance method was in fact a 
class method.  But of course, there isn't anything in the signature to 
indicate that to me.  Apparently, if you do this:

class << self
  def x
  end
end

then x is a class method, not an instance method.

I'm having trouble finding a good explanation of this in the Pickaxe 
book - is someone willing to give me the low down.

This appears to be the common idiom for defining class methods and I'd 
like to understand so I don't waste any more time.

Thanks,
Wes
