<h2>
<a NAME="jjtree"></a>JJDoc</h2>
<p><em>Since Ant 1.6</em></p>
<h3>Description</h3>

<p>Invokes the <a href="http://javacc.dev.java.net/">JJDoc</a> preprocessor
for the JavaCC compiler compiler. It takes a JavaCC parser specification
and produces documentation for the BNF grammar.
It can operate in three modes, determined by command line options.
<p>To use the jjdoc task, set the <i>target</i> attribute to the name
of the JavaCC grammar file to process. You also need to specify the directory
containing the JavaCC installation using the <i>javacchome</i> attribute,
so that ant can find the JavaCC classes. Optionally, you can also set the
<i>outputfile</i> to write the generated BNF documentation file to a specific (directory and) file.
Otherwise jjdoc writes the generated BNF documentation file as the JavaCC
grammar file with a suffix .txt or .html.</p>
<p>This task only invokes JJDoc if the grammar file is newer than the
generated BNF documentation file.</p>
