I'm sure some project out there already has this name. However I love to stomp on other people's namespaces. What gnome-gpg is is a simple command-line wrapper around gpg that makes it store its passphrase in gnome-keyring. It is a direct competitor to (the unmaintained) quintuple-agent. Plus leverages the GNOME authentication dialogs for a much nicer UI.
It is not a keyring management program or anything like that, and has no plans to become one.
gnome-gpg is maintained in Arch.

Comments, questions, and heaps of flames about how I named this project the same as your personal old abandoned GNOME frontend to GPG can be directed here.
