Short and simple:

- Put recv-keys, sync-keys, and send-keys (symlink to recv-keys) someplace in your path

- Copy keyservers to $HOME/.keyservers

- Copy keyservers.ldap to $HOME/.keyservers.ldap

- Invoke recv-keys, send-keys, or sync-keys to receive, send, or sync keys with the keyservers
  listed in the two keyservers files

New:

- LDAP keyservers are supported

- Scripts will backup your pubring.gpg automatically incase you run into a GnuPG bug
  that corrupts the keyring

- syncing will update your trustdb between the receive and send phases
