<hr><a name="_details"></a><h2>Detailed Description</h2>
Allows reading of values from configuration files This class allows a module to read from either the main configuration file (inspircd.conf) or from a module-specified configuration file.
<p>
It may either be instantiated with one parameter or none. Constructing the class using one parameter allows you to specify a path to your own configuration file, otherwise, inspircd.conf is read.
