\thisis{legacy}{Legacy Command Names}

The following are legacy macro names that have been changed to conform to
\hia*'s naming convention of starting user-level macros with the prefix |\Hi|.
By default, they will be defined only if they are not previously defined by
another package, but a warning will be issued if another package has defined
them. The options \opt{legacy} and \opt{nolegacy} affect this behavior.

%
% \MacroSpec\hi@legacy@cmd\marg{legacy}\marg{canonical}\marg{xref}\\
% Defines \meta{legacy} to execute \marg{canonical}, after checking whether
% \meta{legacy} exists. The \meta{xref} is used only for manual display
% purposes.
%
%    \begin{macrocode}
\def\hi@legacy@cmd#1#2#3{%
    \hi@legacy@chk#1{%
        \def#1{#2}% Rather than \let, in case macro is redefined later
    }%
}
%    \end{macrocode}
%
% \MacroSpec\hi@legacy@chk\marg{legacy}\marg{if-true}\\
% Checks whether \meta{legacy} ought to be defined. If so, then run
% \meta{if-true}. By default, the test is whether \meta{legacy} is already
% defined, and a warning is issued. Package options change this.

\label{s:legacy-short}
The following are not ``legacy'' commands but rather are shortcuts for the
citation commands described in \sec{iface}.
