+/**
+@file tdevgenericfactory.h
+KDevelop generic plugin factory.
+*/
+
+/**
+This class provides a generic implementation of a KLibFactory for
+use with TDevelop plugins.
+Usually it is convenient to use K_EXPORT_COMPONENT_FACTORY macro
+to create factories for TDevelop plugins. For example, for DummyPlugin
+the factory can be created (in dummyplugin.cpp file) as:
+@code
+typedef TDevGenericFactory<DummyPlugin> DummyPluginFactory;
+K_EXPORT_COMPONENT_FACTORY(libtdevdummyplugin, DummyPluginFactory( data ) )
+@endcode
+Data should be a const static object. This way it complies with the requirements
+for data objecs of TDevGenericFactory constructor.
+
+<b>Important:</b><br>
+There is no need to create @ref TDEAboutData objects. It is more useful to create
+a static const @ref TDevPluginInfo object which can be used also in the constructor
+of a plugin.
+
+For example, dummyplugin.cpp file could contain:
+@code
+#include <tdevplugininfo.h>
+
+static const TDevPluginInfo data("KDevDummyPlugin");
+typedef TDevGenericFactory<DummyPlugin> DummyPluginFactory;
+K_EXPORT_COMPONENT_FACTORY(libtdevdummyplugin, DummyPluginFactory( data ) )
+
+DummyPlugin::DummyPlugin(TQObject *parent, const char *name, const TQStringList & )
+ :TDevPlugin(&data, parent, name)
+{
+}
+@endcode
+
+In the example above the duplication of information is avoided as same @ref TDevPluginInfo
+objects are used for plugin and for plugin factory. This is possible because @ref TDevPluginInfo
+class has an operator to cast @ref TDevPluginInfo to @ref TDEAboutData.
