%    \begin{macrocode}
%<*package>
%    \end{macrocode}
%
% \begin{macro}{\unimathsetup}
% This macro can be used in lieu of or later to override
% options declared when the package is loaded.
%    \begin{macrocode}
\NewDocumentCommand \unimathsetup {m} { \keys_set:nn {unicode-math} {#1} }
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\setmathfont}
% \doarg{font features (first optional argument retained for backwards compatibility)}
% \darg{font name}
% \doarg{font features}
%    \begin{macrocode}
\NewDocumentCommand \setmathfont { O{} m O{} }
  {
    \@@_setmathfont:nn {#1,#3} {#2}
  }
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\setmathfontface}
%    \begin{macrocode}
\NewDocumentCommand \setmathfontface { m O{} m O{} }
  {
    \@@_setmathfontface:Nnn #1 {#2,#4} {#3}
  }
%    \end{macrocode}
%
% Note that \LaTeX’s \cs{SetMathAlphabet} simply doesn’t work to “reset” a maths alphabet font after \verb”\begin{document}”, so unlike most of the other maths commands around we still restrict this one to the preamble.
%    \begin{macrocode}
\@onlypreamble \setmathfontface
%    \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\setoperatorfont}
% TODO: add check?
%    \begin{macrocode}
\NewDocumentCommand \setoperatorfont {m}
  {
    \tl_set:Nn \g_@@_operator_mathfont_tl {#1}
  }
\setoperatorfont{\mathrm}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\addnolimits}
% This macro appends material to the macro containing the list of operators
% that don’t take limits.
%    \begin{macrocode}
\NewDocumentCommand \addnolimits {m}
  {
    \tl_put_right:Nn \l_@@_nolimits_tl {#1}
  }
%    \end{macrocode}
% \end{macro}
%
%
% \begin{macro}{\removenolimits}
% Can this macro be given a better name?
% It removes an item from the nolimits list.
%    \begin{macrocode}
\NewDocumentCommand \removenolimits {m}
  {
    \tl_remove_all:Nn \l_@@_nolimits_tl {#1}
  }
%    \end{macrocode}
% \end{macro}
