%D All tracing flags at the \TEX\ end will be redone this way so
%D that we have a similar mechanism for \TEX\ and \LUA. Also, the
%D currently used if's might become conditionals.

%D This is not really a tracker but for decades it lived in my \type {cont-loc}
%D file. I moved it here because I wanted someone else to use it. This macro is not
%D really useful for users. I kept the \LUA\ variant in \type {cont-loc.mkiv}.
