I just downloaded and used Config::IniFiles yesterday -- I didn't like the OO interface of it very much, but I didn't want to use the tied-hash interface in case someone who didn't understand that feature came along to make changes. It supports a few extensions to the usual Windows INI format with things like here-docs and grouped sections, but it's easy to avoid getting any of that in your output. Overall, it got the job done quickly, with a minimum of BS.
