+This declaration is only useful when option @samp{-t} (or, equivalently, the

 By default, the program assumes the structure component identifier for
 the keyword is @samp{name}.  This option allows an arbitrary choice of
 identifier for this component, although it still must occur as the first
 field in your supplied @code{struct}.

+It permits to specify initializers for the structure members following
