Isn't this a problem with any program/library? Could we go a route where
(for *nix) we check the current working directory for the file, then check
the user account's .local directory, then check the /etc directory for the
any remaining settings? Maybe for Windows use (dare I say it!) the
registry?
(Please excuse the registry idea if this completely flies in the face of
modern Windows development practices, I haven't programmed in Windows since
my days of taking AP Computer Science ten years ago).
