Flexc++ 是一个语法扫描器生成工具，基于正则表达式。与 Flex 和 Flex++ 高度一致。
Changes: Many changes were made in this release. The lex-skeleton was re-factored and many bugs were fixed. The less(n), more(), atBol(), and setBol() functions were implemented. Interactive scanning was fixed. The bugs with the lookahead operator were fixed as well, which required a large refactoring of lex().
