9<para>flex is a tool for generating programs which recognize
10patterns in text. Pattern recognition is very useful in many applications.
11A user sets up rules
12what to look for and flex will make a program that looks for those
13patterns. The reason people use flex is that it is much easier to sets up
14rules for what to look for than to write the actual program that finds
15the text.</para></sect4>
