cvs verify question

[Aaron]

I was wondering if there is any way to 'verify' a download via cvs.  I 
track stable so after i do my update, I'm just wondering if there is 
some way to verify the files i downloaded are correct, not tampered 
with.  I guess I'm thinking of how you can download the file sets and 
then compare MD5s or something like that.  Or is the rsa fingerprint of 
the cvs server we connect to the verification?

Thanks.
