configurator

A configuration management library for programs and daemons. Features include: Automatic, dynamic reloading in response to modifications to configuration files. 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)). Subscription-based notification of changes to configuration properties. 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. For details of the configuration file format, see http://hackage.haskell.org/packages/archive/configurator/latest/doc/html/Data-Configurator.html.
