Confuse 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 Confuse is not to be the configuration file parser library 
with a gazillion features. Instead, it aims to be easy to use and quick 
to integrate with your code. Confuse was called libcfg before, but was 
changed to not confuse with other similar libraries.
