Can Fedora count it rpms?

[Beartooth]

	I'm sitting here watching F19 try to downgrade itself to F18, 
with screenful after screenful flashing by. I know that, if/when it 
completes, it will tell me how many rpms it means to change; what I want, 
though (out of admittedly idle curiosity), is the number of all the rpms 
on the whole machine. Is there a command for that??
