+and daemons.  The features include:
+
+@enumerate
+@item Automatic, dynamic reloading in response to modifications to
+  configuration files.
+@item 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. @code{$(HOME)}).
+@item Subscription-based notification of changes to configuration properties.
+@item An @code{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.
+@end enumerate\n")
