+    \class TQSqlDriverPlugin qsqldriverplugin.h
+    \brief The TQSqlDriverPlugin class provides an abstract base for custom TQSqlDriver plugins.
+
+    \ingroup plugins
+    \mainclass
+
+    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 TQt.
+
+    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 \c Q_EXPORT_PLUGIN macro. See the SQL
+    plugins that come with TQt for example implementations (in the
+    \c{plugins/src/sqldrivers} subdirectory of the source
+    distribution). Read the \link plugins-howto.html plugins
+    documentation\endlink for more information on plugins.
