Hi,
Serafeim Zanikolas wrote two useful scripts after debconf10. In his own words:
Hey all,
I've written a couple of scripts to reduce the pain of the fingerprint
verification one has to do after a key signing party.
These scripts are quick n ugly hacks I haven't considered worthy of sharing,
until I found out yesterday that some people actually do the verification by
hand.
