   \brief Factory for \ref KDUpdater::UpdateOperation

   This class acts as a factory for \ref KDUpdater::UpdateOperation. You can register
   one or more update operations with this factory and query operations based on their name.

   This class follows the singleton design pattern. Only one instance of this class can
   be created and its reference can be fetched from the \ref instance() method.
*/

/*!
   \fn KDUpdater::UpdateOperationFactory::registerUpdateOperation( const QString& name )

   Registers T as new UpdateOperation with \a name. When create() is called with that \a name,
   T is constructed using its default constructor.
