configurator-ng

A configuration management library for programs and daemons. Features include: A simple, but flexible, configuration language, supporting several of the most commonly needed types of data, along with interpolation of strings from the configuration or the system environment (e.g. $(HOME)). An import directive allows the configuration of a complex application to be split across several smaller files, or common configuration data to be shared across several applications. An expressive applicative/monadic high-level parsing interface to gracefully scale to more complicated configuration needs, with powerful diagnostic messaging mechanism.
