 appear in the specification will also appear
in the source file for the <tt>parser</tt> class allowing various names from
that package to be used directly in user supplied action code.

After the package and imports, a specification can include a parser
class name, as follows:

<pre><tt> class <i>name</i>;</tt>
</pre>

If a class name is supplied, then that is the name that will be used
for the generated parser code. As well, the generated symbols class
will have the given name followed by "<tt>Sym</tt>".
