A.16.4. Short descriptions

flex is a tool for generating programs that recognize patterns in text. Pattern recognition is useful in many applications. From a set of rules on what to look for flex makes a program that looks for those patterns. The reason to use flex is that it is much easier to specify the rules for than to write the actual pattern-finding program.

flex++ invokes a version of flex that is used exclusively for C++ scanners.
