+    Your server doesn't have support for PHP 5.
+  </h2>
+  <p>
+    PHP 5 is the latest version of the language on which Enano was built. Its many new features have been available since early 2004, yet
+    many web hosts have not migrated to it because of the work involved. In 2007, Zend Corporation announced that support for the aging
+    PHP 4.x would be discontinued at the end of the year. An initiative called <a href="http://gophp5.org/">GoPHP5</a> was started to
+    encourage web hosts to migrate to PHP 5.
+  </p>
+  <p>
+    Because of the industry's decision to not support PHP 4 any longer, the Enano team decided that it was time to begin using the powerful
+    features of PHP 5 at the expense of PHP 4 compatibility. Therefore, this version of Enano cannot be installed on your server until it
+    is upgraded to at least PHP 5.0.0, and preferably the latest available version.
+    <!-- No, not even removing the check in this installer script will help. As soon as the PHP4 check is passed, the installer shows the
+         language selection page, after which the language code is loaded. The language code and libjson2 will trigger parse errors under
+         PHP <5.0.0. -->
+  </p>
+  <p>
+    If you need to use Enano but can't upgrade your PHP because you're on a shared or reseller hosting service, you can use the
+    <a href="http://enanocms.org/download?series=1.0">1.0.x series of Enano</a> on your site. While the Enano team attempts to make this
+    older series work on PHP 4, official support is not provided for installations of Enano on PHP 4.
