Description:

libConfuse is a configuration file parser library, licensed under
the terms of the LGPL, and written in C. It supports sections and
(lists of) values (strings, integers, floats, booleans or other
sections), as well as some other features (such as
single/double-quoted strings, environment variable expansion,
functions and nested include statements).

It makes it very easy to add configuration file capability to a
program using a simple API. The goal of libConfuse is not to be
the configuration file parser library with a gazillion of features.
Instead, it aims to be easy to use and quick to integrate with your
code.
