OK, the dishes are done and an idea is forming here. How about something along the lines of:

=head1 SYNOPSIS

my $installation_cfg = Config::Simple->new( file => '/etc/app_name/app
+_name.ini' );

my $client_cfg = Config::Simple::Inherit->new(
     base_config => $installation_cfg,
     file => '/etc/app_name/client_name/app_name.ini',
);

my $job_cfg = Config::Simple::Inherit->new(
     base_config => $client_cfg,
     file => '/etc/app_name/client_name/app_job_id.ini',
);

Does that seem like a reasonable interface to have to deal with? Makes me start thinking of the other missing for me in Config::Simple, namely Config::Simple::Heredoc, or am I making this less simple than it really ought to be? Or worse yet, reinventing a wheel needlessly?

Thoughts?
