+    \class QSqlDriverPlugin
+    \brief The QSqlDriverPlugin class provides an abstract base for custom QSqlDriver plugins.
+
+    \ingroup plugins
+    \inmodule QtSql
+
+    The SQL driver plugin is a simple plugin interface that makes it
+    easy to create your own SQL driver plugins that can be loaded
+    dynamically by Qt.
+
+    Writing a SQL 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. See the SQL
+    plugins that come with Qt for example implementations (in the
+    \c{plugins/src/sqldrivers} subdirectory of the source
+    distribution).
+
+    \sa {How to Create Qt Plugins}

+
+/*!
+    \fn QStringList QSqlDriverPlugin::keys() const
+
+    Returns the list of drivers (keys) this plugin supports.
+
+    These keys are usually the class names of the custom drivers that
+    are implemented in the plugin.
+
+    \sa create()
