+Add/update a user ID to the authorized_user_ids file. The user IDs
+specified should be exact matches to OpenPGP user IDs. For each
+specified user ID, gpg will be queried for a key associated with that
+user ID, querying a keyserver if none is found in the user's keychain.
+If a key is found, it will be added to the user_keys cache (see KEY
+CACHES) and the user ID will be added to the user's
+authorized_user_ids file (if it wasn't already present). `u' may be
+used in place of `update-userids'.
+.TP
+.B remove-userids [USERID]...
+Remove a user ID from the authorized_user_ids file. The user IDs
+specified should be exact matches to OpenPGP user IDs. `r' may be
+used in place of `remove-userids'.
+.TP
+.B update-authorized_keys
+Update the monkeysphere authorized_keys file. The monkeysphere
+authorized_keys file will be regenerated from the valid keys in the
+user_key cache, and the user's independently controlled
+authorized_keys file (usually ~/.ssh/authorized_keys). `a' may be
+used in place of `update-authorized_keys'.
