Thread:User talk:IAlex/Configure $wgConfigureAdditionalExtensions

I'm a newbie extension author here... am I to understand that without changing any files in Configure I can add Configure support for my extension using $wgConfigureAdditionalExtensions? Is this the prefered way to do it? Where should I be putting this in my extension.php file? In the constructor for my extension class? Will you load it, otherwise how would it ever get called? Am I forced to use a init function instead?
