Description:

libConfuse is a configuration file parser library, licensed under the terms
of the ISC license, 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. libConfuse was called libcfg before, but was
changed to not confuse with other similar libraries.
