+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 specified. If a key is found, 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. For each user ID in the
+user's authorized_user_ids file, gpg will be queried for keys
+associated with that user ID, querying a keyserver if specified. If a
+key is found, it will be converted to an ssh key, and any matching ssh
+keys will be removed from the user's authorized_keys file. If the
+found key is acceptable (see KEY ACCEPTABILITY), then the key will be
+updated and re-added to the authorized_keys file. If no gpg key is
+found for the user ID, then nothing is done. `a' may be used in place
+of `update-authorized_keys'.
