Sorry, missed the environment part while reading
as you wrote the french version ;-)

I would take the the environment variable as last option
because that's not very intuitive for the end user.
(f.e. program crashes because he/she forget to set it)

That would be an option, though it's still messy. Is there a garantuee
from the compiler in which order global objects are created?
