    \class KDUpdater::UpdateOperationFactory
    \brief The UpdateOperationFactory class is used to create update operations based on their name.

    This class acts as a factory for \c 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 instance() method.

    The following operations are registered by default:
    \list
        \li Copy operation
        \li Move operation
        \li Delete operation
        \li Mkdir operation
        \li Rmdir operation
        \li AppendFile operation
        \li PrependFile operation
    \endlist
*/

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

    Registers a new update operation with the factory based on \a name. When create() is called
    with that \a name, the update operation is constructed using its default constructor.

    Returns the UpdateOperationFactory instance. The instance is created if needed.
