Руководство по стандартной библиотеке шаблонов (STL)

Эти примеры демонстрируют использование нового продукта STL ‹ToolKit› от компании ObjectSpace. STL ‹ToolKit› - это самый простой способ использования STL, который работает на большинстве комбинаций платформ/компиляторов, включая cfront, Borland, Visual C++, Set C++, ObjectCenter и последние компиляторы от Sun&HP.
