Листинг 8. Листинг ListTable.Htm Выводы

В ходе данной работы мы изучили основные принципы построения веб-страниц на языке HTML, а также разработали кроссплатформенный легкопереносимый удобный генератор всего набора веб-страниц из исходных шаблонов. Кроме того, в программе использован модуль gettext, который позволяет создавать локализации приложения на любых языках в любых системах.
