Hi all,

I guess this question might be more suited on gnupg-users, but as I'm 
not subscribed to that list, I hope you can forgive me for asking 
here... It is a really short question...

Is there a way to remove revoked/expired and otherwise invalid or 
useless keys from a GPG keyring, in batch?

I once downloaded the 4500 keys that were closest to me, but many of 
them are invalid now, and I'd like to remove those in a quick way? Are 
there possibly any scripts lying around? 

Cheers,

Kjetil
