- <h2><a name="antlr">ANTLR</a></h2>
- <h3>Description</h3>
- <p>
- Invokes the <a HREF="http://www.antlr.org/">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.
