[Boost-users] Cross platform library for reading/writing configuration files?

I've used Windows specific functions for reading/writing configuration (INI) files in my application and would like to know if there is a cross platform library available that is recommended. I searched the boost libs for something and there are libs of course that can achieve this with some programming, but I'd like to know if there is something (boost or other library) with specific functionality to handle reading/writing INI files. Example: [General] Language=Français [Strings] String00001=Version String00002=Etes vous sûr ? String00003=Voulez-vous continuer ? Thank you very much
