+
+The ebnflint program verifies that EBNF productions in an HTML document
+such as the Go specification document are consistent and grammatically correct.
+
+Grammar productions are grouped in boxes demarcated by the HTML elements
+	<pre class="ebnf">
+	</pre>
+
+
+Usage:
+	ebnflint [--start production] [file]
+
+The --start flag specifies the name of the start production for
+the grammar; it defaults to "Start".
