% Typeset fenced code with infostring `mermaid` using the command `mmdc` from
% the npm package `@mermaid-js/mermaid-cli`.
% the npm package `@mermaid-js/mermaid-cli`. The exact command can be
% configured by redefining or appending to the
% \mdef{g_@@_diagrams_mmdc_command_tl} token list or by redefining the
% \mdef{mmdcCommand} macro. Unlike the token list, the macro can be redefined
% even before loading the Markdown package.
