2 * TazWeb is a radically simple web browser providing a single window
3 * with a single toolbar with buttons, a URL entry and search as well
4 * as a contextual menu, but no menu bar or tabs. Commented line code
5 * starts with // and comments are between * *
6 *
7 * NEXT GENERATION
8 * This is TazWeb NG (2.0) with tabs and cookies support :-)
