+%D \macros
+%D {definefilesynonym,definefilefallback}
+%D
+%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 \dodefinefilesynonym}
+\unexpanded\def\definefilefallback{\dodoubleargument\dodefinefilefallback} % still used?
+
+\def\dodefinefilesynonym [#name][#realname]{\ctxcommand{definefilesynonym ("#name","#realname")}}
+\def\dodefinefilefallback[#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.
