/**
 * Simple interface for displaying request profile data stored in
 * the wikis' primary database.
 *
 * See also https://www.mediawiki.org/wiki/Manual:Profiling.
 *
 * To add profiling information to the database:
 *
 * - set $wgProfiler['class'] in LocalSetings.php to a Profiler class other than ProfilerStub.
 * - set $wgProfiler['output'] to 'db' to force the profiler to save its the
 *   information in the database.
 * - apply the maintenance/archives/patch-profiling.sql patch to the database.
 * - set $wgEnableProfileInfo to true.
