%% When you supply a default value for optional or keyword arguments,
%% use this idiom:  \key (filled \cl{t})
%% \newcommand {\cl} [1] {{\tt #1}}

%% This allows hyphenation of CL symbols at the hyphens that exist in
%% the symbol name, but noplace else, e.g., \cl{standard\-region\-union}.
%% The reason we don't use this is that the backslashes in the symbol
%% names make Tags Search next to useless.
%% \def\cl#1{{\def\-{\discretionary{-}{}{-}}\tt #1}}

%% Spiffier version that hyphenates only at hyphens, but makes hyphens
%% be active characters, so we don't break Tags Search.  Thanks to
%% Stephen Gildea for providing this.
