+ *
+ * -- Notes for users HTTP_Upload >= 0.9.0 --
+ *
+ * Error detection was enhanced, so you no longer need to
+ * check for PEAR::isError() in $upload->getFiles() or call
+ * $upload->isMissing(). Instead you'll
+ * get the error when do a check for $file->isError().
+ *
+ * Example:
+ *
+ * $upload = new HTTP_Upload('en');
+ * $file = $upload->getFiles('i_dont_exist_in_form_definition');
+ * if ($file->isError()) {
+ * die($file->getMessage());
