Thanks. I see I was not precise enough. What I have here is a legacy code - it is one huge class (i.e. package) split into many files for easier editing. This splitting breaks the usual assumption about the correspondence between the file name and the package contained in it. I guess I can live with that if I have - but it would nice to at least organise my new code in a more intuitive (i.e. standard) way. I am now looking into C:A:Dispatch - it is promising.
