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.
