% \begin{abstract}
%   This package fixes ACM's \package{sig-alternate} class so it  uses
%   NFSS (new font selection scheme).  Among other things, it  ensures
%   that fonts in the headings are scaled correctly.

%D% % Slightly embarrasing, the very first part of the \LaTeX\ code is a
%D% % hack on \LaTeX\ to make it believe that it is loading the package
%D% % "pmn-sigalternate-nfss.sty" when printing the documentation.

%D% \def\@currname{pmn-sigalternate-nfss} 
%D% \def\@currext{sty}
%D% %</documentation>
%D% %    \end{macrocode}
% \cmd{\@currname} and \cmd{\@currext} are the internal \LaTeX-macros containg
% the name and extension of the package currently being loaded;
% setting these prevents an error from \cmd{\ProvidesPackage}.
% 
%  Since we use \cmd{\renewcommand} we have to make sure that all
%  commands are defined before processing the documentation.

% \begin{macro}{\pmn@sa@iftimesnewroman}
%   \mcmd{\pmn@sa@iftimesnewroman}\marg{consequence} is a flag that
%   tells that we want Times New Roman as font for the running text.
%   If so \meta{consequence} is applied; otherwise it is ignored.
%   It is set with the option "times-new-roman" and cleared with the
%   option "computer-modern" (default).
%    \begin{macrocode}
\let\pmn@sa@iftimesnewroman\@gobble
\DeclareOption{times-new-roman}{\let\pmn@sa@iftimesnewroman\@iden}
\DeclareOption{computer-modern}{\let\pmn@sa@iftimesnewroman\@gobble}
%    \end{macrocode}
%   Technically, we use \LaTeX's "\@iden" or "\gobble" to other set or
%   swallow the argument.
% \end{macro} ^^A \pmn@sa@iftimesnewroman

% If we want Times New Roman we load the package~\package{times}, but
