How to identify kernel

[Michael Wileman <jwileman%panix.com@localhost>]

My current kernel tells me it is 3.99.3. I downloaded today's 
snapshot, and it identifies itself as  3.0_BETA (GENERIC) #0. Can 
someone tell me what this means. I thought all betas were identified 
as .99 and the final decimal indicates changes. But the snapshot with 
#0 seems to indicate this is the first one. I'd like to be able to 
keep track.
