-.B ssh-proxycommand
-an ssh proxy command that can be used
-to trigger a monkeysphere update of the ssh known_hosts file for a
-host that is being connected to with ssh. This works by updating the
-known_hosts file for the host first, before an attempted connection to
-the host is made. Once the known_hosts file has been updated, a TCP
-connection to the host is made by exec'ing netcat(1). Regular ssh
-communication is then done over this netcat TCP connection (see
-ProxyCommand in ssh_config(5) for more info).
+`update\-known_hosts'.

+.B update\-authorized_keys
+Update the authorized_keys file for the user executing the command
+(see MONKEYSPHERE_AUTHORIZED_KEYS in ENVIRONMENT, below). First all
+monkeysphere keys are cleared from the authorized_keys file. Then,
+for each user ID in the user's authorized_user_ids file, gpg will be
+queried for keys associated with that user ID, optionally querying a
+keyserver. If an acceptable key is found (see KEY ACCEPTABILITY in
+.BR monkeysphere (7)),
+the key is added to the user's authorized_keys file.
+If a key is found but is unacceptable for the user ID, any matching
+keys are removed from the user's authorized_keys file. If no gpg key
+is found for the user ID, nothing is done. This subcommand will exit
+with a status of 0 if at least one acceptable key was found for a user
+ID, 1 if no matching keys were found at all, and 2 if matching keys
+were found but none were acceptable. `a' may be used in place of
+`update\-authorized_keys'.
+.TP
+.B gen\-subkey [KEYID]
+Generate an authentication subkey for a private key in your GnuPG
+keyring. KEYID is the key ID for the primary key for which the subkey
+with "authentication" capability will be generated. If no key ID is
+specified, but only one key exists in the secret keyring, that key
+will be used. The length of the generated key can be specified with
+the `\-\-length' or `\-l' option. `g' may be used in place of
+`gen\-subkey'.
+.TP
+.B ssh\-proxycommand [--no-connect] HOST [PORT]
+An ssh ProxyCommand that can be used to trigger a monkeysphere update
+of the ssh known_hosts file for a host that is being connected to with
+ssh. This works by updating the known_hosts file for the host first,
+before an attempted connection to the host is made. Once the
+known_hosts file has been updated, a TCP connection to the host is
+made by exec'ing netcat(1). Regular ssh communication is then done
+over this netcat TCP connection (see ProxyCommand in ssh_config(5) for
+more info).
