I use App::Options to manage the configuratio of my program. The main
program name is main.pl and the cofiguration file main.conf.
Everything works fine for main.pl: if main.conf is present, its
content is used to configure main.pl.
Other than main.pl, I want another program to share the main.conf
configuration file: I want second.pl to use main.conf configurations.
but, no way. second.pl doesn't use the main.conf information.
Everything works if I copy main.conf to second.conf file. I don't want
to have two separate but identical files for configurations so I'd
want second.pl to use main.conf.
