Overview

This is a helper class (not meant to be used externally). The Ruby code in Ruby configuration files is executed in the context of the instances of this class. It provides a config instance method that allows references to “config.param_name” in the configuration file to work. This method returns a ObjectProxy, which in turn re-implements method_missing so as to allow references to arbitrary parameters.
