% \paragraph{Hooks for Memo and Review Formats}

% this package can add to for special processing depending on style. The hooks
% will be executed at the end of the package.

%</doc>

%    \end{macrocode}

%<*doc>

%<*doc>

\ExplainOption{somenotename} In general, if a case is named inline in text and
a citation to the case is made immediately thereafter, then the case name is
suppressed in the citation so as to avoid redundancy. This option makes an
exception where the citation to the case is the first citation in a footnote. In
such cases, the inline use was in text potentially distant from the footnote, so
naming the case again in the footnote is less redundant and potentially helpful
to readers.

%</doc>

\DeclareOption{somenotename}{\hi@noname@sometimes}
%    \end{macrocode}
%</package>
%<*doc>

\ExplainOption{nonotename} Suppresses case names even in citations at the
start of footnotes. This is typical of most legal journals.

%</doc>
%<*package>
%    \begin{macrocode}
\DeclareOption{nonotename}{\hi@noname@always}

package's definition intact (see \sec{urls}).

\DeclareOption{nooverrideurl}{%
    \let\hi@url@override\relax
