Use Config::Loader Config::Merge - it handles exactly this problem. It can:

• read files containing YAML, JSON, XML, INI, Perl and Config::General data
• recurse through a directory tree loading the config (hash or array) at the correct point in the config hash
• merge values for local config into the tree, to allow you to handle development and production environments safely

Update: Changed the module name to reflect its new name
