%C details.
\writestatus{loading}{ConTeXt TeX Logos}
%D The system that is used to typeset this text is called \TEX, typeset with an
%D lowered~E. From te beginning of \TEX, authors of macro packages adapted this
%D raising and lowering style. In this module we define some of those logos.
%D We define the uppercase logo commands as (unfrozen) instances because they can be
%D redefined in the synonyms modules.
