%D Most of \CONTEXT is preloaded in the format file. Some very domain specific
%D typesetting topics are however dealt with in separate modules, e.g. typesetting
%D of chemical structure formulas. These modules are loaded by:
%D
%D \showsetup{usemodule}
%D
%D More information on the specific modules can be found in their dedicated manuals.
%D We use \type {\next} so that we can \type {\end} in modules.
