which kubuntu version am i running?

[Roger Searle]

Hi, trivial question for the day: I fired up a laptop that I don't often 
use, that I have a kubuntu distro installed on, and am not sure if it is 
feisty or gutsy.  It's not obvious where I should look to see distro 
version.  I can easily find my KDE or kernel version.  Googling for a 
command gives me so much info about "ubuntu versions" or command line 
commands, but not for the 2 together.  Where is the easy way to see?

Cheers,
Roger
