Flex-style scanner generator for C++

 Flexc++ was designed after `flex'. Flexc++ offers as compared to flex's C++
 option a cleaner class-design.
 .
 Flexc++ generates a scanner class that is ready for use, as well as a member
 function producing the lexical scanner tokens (lex()). The class can easily
 be provided with additional members without the need for polymorphic
 functions. Consequently, classes generated by flexc++ have no virtual members
 and actually have but one public member: lex(), replacing the old-style flex
 and flex++ yylex() function.
 .
 Flexc++ offers many options, among which an option to define classes
 generated by flexc++ in a separate namespace. This allows developers to
 define additional symbols, even outside of the class generated by flexc++,
 without encountering name-collision problems. With flexc++, artificial means
 to prevent name-collisions, like the yy-conventions used by flex and flex++
 are no longer required. Flexc++ generates C++ code. If C code is required,
 flex should be used. Flexc++'s grammar requirements are highly compatible
 with flex's requirements, so converting a flex grammar into a flexc++ grammar
 should be fairly simple.
 .
 In addition to the flexc++ scanner generator itself and several skeleton
 files, the package contains an extensive man-page, as well as a full manual
 rewritten after the original flex manual, and several examples.
