+/*!
+    \class QIconEnginePlugin
+    \brief The QIconEnginePlugin class provides an abstract base for custom QIconEngine plugins.
+
+    \ingroup plugins
+    \inmodule QtGui
+
+    \b {Use QIconEnginePluginV2 instead.}
+
+    The icon engine plugin is a simple plugin interface that makes it easy to
+    create custom icon engines that can be loaded dynamically into applications
+    through QIcon. QIcon uses the file or resource name's suffix to determine
+    what icon engine to use.
+
+    Writing a icon engine plugin is achieved by subclassing this base class,
+    reimplementing the pure virtual functions keys() and create(), and
+    exporting the class with the Q_EXPORT_PLUGIN2() macro.
+
+    \sa {How to Create Qt Plugins}
+*/
+
+/*!
+    \fn QStringList QIconEnginePlugin::keys() const
+
+    Returns a list of icon engine keys that this plugin supports. The keys correspond
+    to the suffix of the file or resource name used when the plugin was created.
+    Keys are case insensitive.
+
+    \sa create()
