 * 1) First, it includes WebStart.php (SVN), which includes LocalSettings.php and Setup.php (SVN).
 * 2) Next it instantiates a MediaWiki object called $mediaWiki which is defined in Wiki.php.
 * 3) It then checks the maxlag parameter, which may cause the request to be rejected.
 * 4) It calls the function   in Wiki.php, which creates a Title object depending of the title and action parameters from the URL.
 * 5) If ajax is enabled and the   parameter is set to , then an AjaxDispatcher object will be created to handle that request and the script will stop after that.
 * 6) Otherwise some globals are stored in $mediaWiki to be used in the next steps.
 * 7) It calls   which does most of the work of the request.
 * 8) Then   is called.  That function does the deferred updates, runs jobs from the queue depending on $wgJobRunRate and outputs the HTML by calling.
 * 9) Finally,   is called to log profiling data.
