+	    <p>A note regarding the <c>includefile</c> option:
+	    although yecc can cope with includefiles based on some
+	    earlier <c>yeccpre.hrl</c> it is recommended for
+	    efficiency reasons to update includefiles as to follow
+	    the pattern in the latest <c>yeccpre.hrl</c>.</p>

+      <p>Several modifications of Yecc have been made:</p>
+      <list type="bulleted">
+        <item>
+          <p>The new functions <c>file/1,2</c> take the
+            role of the old functions <c>yecc/2,3,4</c>. The
+            latter functions are no longer documented but are
+            kept for backward compatibility.</p>
+        </item>
+        <item>
+          <p>More checks of the grammar file have been 
+            implemented. Examples are warnings for unused 
+            non-terminals and duplicated declarations.</p>
+        </item>
+        <item>
+          <p>Invalid pseudo variables are no longer 
+            replaced by <c>'$undefined'</c> but cause a failure.</p>
+        </item>
+        <item>
+          <p>Reserved words no longer need to be quoted
+            when used as terminals or non-terminals.</p>
+        </item>
+        <item>
+          <p>When compiling the generated parser file errors
+            and warnings concerning user code refer to 
+            the grammar file, not the parser file.</p>
+        </item>
+        <item>
+          <p>Yecc emits a warning if there are conflicts
+            in the grammar. The new declaration <c>Expect</c> can
+            be used to suppress this warning.</p>
+        </item>
+        <item>
+          <p>The new operator precedence declaration
+            <c>Nonassoc</c> can be used to declare operators with
+            no associativity.</p>
+        </item>
+        <item>
+          <p>Precedence can be given to more than one operator
+            with one single operator precedence declaration.</p>
+        </item>
+        <item>
+          <p>The function <c>parse_and_scan/1</c> in the
+            default includefile accepts <c>{Function, A}</c>
+            as well as {{M,F}, A} as tokenizer function.
+            Exceptions in the tokenizer are never caught.</p>
+        </item>
+        <item>
+          <p>The functions <c>yecc:file/1,2</c> can be accessed
+            from the Erlang shell via the new functions <c>c:y/1,2</c> 
+            in STDLIB.</p>
+        </item>
