gpglist was written by me in 2004 to help at the linuxtag 2004 keysigning party. It has since been massively overworked and redone by Peter Palfrader and Christoph Berg, and, since a few years, is maintained at the alioth site of pgp-tools.
gpglist is included in the the Debian package signing-party. If you don't use Debian, you could fetch it directly from its subversion repository.
