="precedence"></a>2.4 Precedence and Associativity declarations</h4>

The third section, which is optional, specifies the precedences and
associativity of terminals.  This is useful for parsing with ambiguous
grammars, as done in the example above. There are three type of
precedence/associativity declarations:
<pre><tt>
	precedence left     <i>terminal</i>[, <i>terminal</i>...];
	precedence right    <i>terminal</i>[, <i>terminal</i>...];
	precedence nonassoc <i>terminal</i>[, <i>terminal</i>...];
</tt></pre
