/**
 * \class KPluginLoader kpluginloader.h <KPluginLoader>
 *
 * This class can be used to dynamically load a plugin library at runtime.
 *
 * This class makes sure that the Qt and KDE versions used to compile this library aren't newer then
 * the ones currently used.
 *
 *
 * This class is reentrant, you can load plugins from different threads. You can also have multiple
 * PluginLoaders for one library without negative effects.
 * The object obtained with factory() or the inherited method QPluginLoader::instance() is
 * cached inside the library. If you call factory() or instance() multiple times, you will always get
 * the same object, even from different threads and different KPluginLoader instances.
 * You can delete this object easily, a new one will be created if factory() or instance() is called
 * afterwards. factory() uses instance() internally.
 *
 * KPluginLoader inherits QPluginLoader::unload(). It is safe to call this method if you loaded a plugin
 * and decide not to use it for some reason. But as soon as you start to use the factory from the plugin,
 * you should stay away from it. It's nearly impossible to keep track of all objects created directly or
 * indirectly from the plugin and all other pointers into plugin code. Using unload() in this case is asking
 * for trouble. If you really need to unload your plugins, you have to take care to convert the clipboard
 * content to text, because the plugin could have registered a custom mime source. You also have to delete
 * the factory of the plugin, otherwise you will create a leak.
 * The destructor of KPluginLoader doesn't call unload.
 *
 * Sample code:
 * \code
 *  KPluginLoader loader( ...library or kservice... );
 *  KPluginFactory* factory = loader.factory();
 *  if (!factory) {
 *      kWarning() << "Error loading plugin:" << loader.errorString();
 *  } else {
 *      MyInterface* obj = factory->create<MyInterface>();
 *      if (!obj) {
 *          kWarning() << "Error creating object";
 *      }
 *  }
 * \endcode
 *
 * \see KPluginFactory
