| 11 | <para>flex is a tool for generating programs which recognize
|
|---|
| 12 | patterns in text. Pattern recognition is very useful in many applications.
|
|---|
| 13 | A user sets up rules
|
|---|
| 14 | what to look for and flex will make a program that looks for those
|
|---|
| 15 | patterns. The reason people use flex is that it is much easier to sets up
|
|---|
| 16 | rules for what to look for than to write the actual program that finds
|
|---|
| 17 | the text.</para></sect4>
