1. Called from $wgExtensionFunctions array when initialising extensions

function wfSetupSimpleForms() { global $wgHooks,$wgSimpleForms,$wgJavaScriptFunctions; $wgSimpleForms = new TreeView($wgTreeViewMagic); if (!is_array($wgJavaScriptFunctions)) { $wgJavaScriptFunctions = array(); $wgHooks['OutputPageBeforeHTML'][] = $this; } }

1. Needed in MediaWiki >1.8.0 for magic word hooks to work properly
