This review is not meant as an actual review of the module, but to draw attention to the fact that development of it has long since stopped and that you should consider other modules like Config::INI::Reader and Config::INI::Writer instead.
I really like Config::Simple for writing and parsing configuration files. It supports different file types of configuration files - just use the one you like. Also the author is very friendly and supportive if you've a problem or a question. I recenctly converted nearly all my scripts that need a configuration file management to Config::Simple.
I hope that Sherzod will continue his good job in the future - what about adding an XML configuration style? :-)
