| <h2><a name="antlr">ANTLR</a></h2> |
| <h3>Description</h3> |
| <p> |
| Invokes the <a HREF="http://www.antlr.org/" target="_top">ANTLR</a> Translator generator |
| on a grammar file. |
| </p> |
| <p> |
| To use the ANTLR task, set the <i>target</i> attribute to the name of the |
| grammar file to process. Optionally, you can also set the |
| <i>outputdirectory</i> to write the generated file to a specific directory. |
| Otherwise ANTLR writes the generated files to the directory containing |
| the grammar file. |
| </p> |
| <p> |
| This task only invokes ANTLR if the grammar file is newer than the generated |
| files. |
| </p> |
| |

| <td valign="top">fork</td> |

| files to build/src. |
