-``ndnsec-get-default`` is a tool to display the default setting of a particular entity.
+Synopsis

+**ndnsec-get-default** [**-h**] [**-k**\|\ **-c**] [**-i** *identity*\|\ **-K** *key*] [**-q**]
 
 Description
 -----------
 
-Given a particular entity, ``ndnsec-get-default`` can display its default setting as specified in
-options. If ``identity`` is specified, the given entity becomes the identity. If ``key`` is
-specified, the given identity becomes the key. If no entity is specified, the command will take the
-system default identity as the given entity.
+Given a particular entity, :program:`ndnsec-get-default` shows its default settings
+according to the command-line options. By default, if neither **-i** nor **-K** is
+given, the command displays the default identity or the default key/certificate of
+the default identity.
