in reply to Which configuration module?
I use Config::Simple it works very well, except for the tied hash interface where it flattens the sections into a single hash which when dumped looks like:
The tied method of Config::IniFiles is more intuitive.'newsletter.owner_p1_font' => , 'newsletter.contact_font' => 'Helvetica', 'newsletter.owner_city' => 'Hamilton', 'system.debug' => '1', 'armtwo.username' => , 'newsletter.contact_y' => '150',
Config::Simple is pretty widely used and if you have a problem the developer is very responsive.
