    97 <para>is a tool for generating programs that
    98 recognize patterns in text. Pattern recognition is useful in many applications.
    99 From a set of rules on what to look for, <command>flex</command> makes a program that looks for
    100 those patterns. The reason to use <command>flex</command> is that it is much easier to specify
    101 the rules for a pattern-finding program than to write the program.</para>
