Remind me (pls)... Distro Version Discovery

[Adam McGreggor]

Heya,

Stupid dumbass question here, which is bugging me, as it's really
slipped my mind...

I'm after the app which tells me which *distro* I'm using, and the
version; it's not uname(1), and I've seen it posted before, here 
(greping 450MB of list-archive just ain't gonna happen).

Anyone know what I'm thinking of? (And I don't want to switch to
TTY[0-6]...

TIA,

A
