| 12 | .Sh DESCRIPTION |
| 13 | .Nm |
| 14 | is an LALR(1) parser generator for C or C++. |
| 15 | It does the same job as bison and yacc. |
| 16 | But |
| 17 | .Nm |
| 18 | is not another bison or yacc clone. |
| 19 | It uses a different grammar syntax which is designed to reduce the number of coding errors. |
| 20 | .Nm |
| 21 | also uses a more sophisticated parsing engine that is faster than yacc and bison |
| 22 | and which is both reentrant and thread-safe. |
| 23 | Furthermore, |
| 24 | .Nm |
| 25 | implements features that can be used to eliminate resource leaks, |
| 26 | making is suitable for use in long-running programs such as graphical user interfaces or embedded controllers. |
| 27 | .Pp |
| 28 | .Nm |
| 29 | will read the grammer from |
| 30 | .Ar input |
| 31 | and write out a parser for that grammar in the C language. |
