+ *
+ * Note: The older util.php class simply printed a string, but the spec
+ * says that 500 errors should be treated similarly to 400 errors, and
+ * it's easier to give an HTML response.  Maybe we can customize these
+ * to display some funny animal cartoons.  If not, we can probably role
+ * these classes up into a single class.
