/**
 * MediaWiki installer overrides.
 * Modify this file if you are a packager who needs to modify the behavior of the MediaWiki installer.
 * Altering it is preferred over changing anything in /includes.

 * Note: this file doesn't gets included from a global scope, don't use globals directly.

/*

Example of modifications:

	public static function getLocalSettingsGenerator( Installer $installer ) {
		return new MyLocalSettingsGenerator( $installer );
	}

Then add the following to the bottom of this file:

class MyLocalSettingsGenerator extends LocalSettingsGenerator {
	function getText() {
		// Modify an existing setting
		$this->values['wgResourceLoaderMaxQueryLength'] = 512;
		// add a new setting
		$ls = parent::getText();
		return $ls . "\n\$wgUseTex = true;\n";
	}
}
