+Generate (with the option to publish) a revocation certificate for the
+host's OpenPGP key. If such a certificate is published, your host key
+will be permanently revoked. This subcommand will ask you a series of
+questions, and then generate a key revocation certificate, sending it
+to stdout. If you explicitly tell it to publish the revocation
+certificate immediately, it will send it to the public keyservers.
+USE WITH CAUTION!
