I must say I still don't understand the purpose of this library. This is not a troll, I have a few serious questions:
* Why would you want to use this library rather than simple binary config files, which are much smaller? In a well-done program, you'll need a GUI for configuration editing anyway, so what's the point of using a text-based format?
* What's so new about this? You can easily parse an INI-format config file using fscanf.
