devel/p5-Config-Onion 1.007nb7 NetBSD

All too often, configuration is not a universal or one-time thing, yet most configuration-handling treats it as such. Perhaps you can only load one config file. If you can load more than one, you often have to load all of them at the same time or each is stored completely independently, preventing one from being able to override another. Config::Onion changes that.

Config::Onion stores all configuration settings in four layers: Defaults, Main, Local, and Override. Each layer can be added to as many times as you like. Within each layer, settings which are given multiple times will take the last specified value, while those which are not repeated will remain untouched.
