%D One of the problems with loading files is that their names
%D can depend on the interface language. We therefore need a
%D method to define filesynonyms. The actual synonyms are
%D defined elsewhere, but look like:
%D
%D \starttyping
%D \definefilesynonym [chemic] [chemie]
%D \definefilesynonym [einheit] [unit]
%D \definefilesynonym [unit] [unit]
%D \stoptyping
%D
%D So we can say in english:
%D
%D \starttyping
%D \usemodules[pictex,chemic,unit]
%D \stoptyping
%D
%D and in dutch:
%D
%D \starttyping
%D \usemodules[pictex,chemie,unit]
%D \stoptyping
\unexpanded\def\definefilesynonym {\dodoubleempty \syst_files_define_synonym }
\unexpanded\def\definefilefallback{\dodoubleargument\syst_files_define_fallback} % still used?
\def\syst_files_define_synonym [#name][#realname]{\ctxcommand{definefilesynonym ("#name","#realname")}}
\def\syst_files_define_fallback[#name][#alternatives]{\ctxcommand{definefilefallback("#name","#alternatives")}}
%D \macros
%D {truefilename}
%D
%D At the system level such a filename can be called upon by
%D saying:
%D
%D \starttyping
%D \truefilename{filename/filesynonym}
%D \stoptyping
%D
%D The implementation shows that nesting is supported.
\def\truefilename#1{\ctxcommand{truefilename("#1")}}
