+====== A Renderer Plugin for DokuWiki ======
+...which does not run :-(
+I find it annoying that the quotation marks are hardcoded in DokuWiki's source code. At the moment, I have a workaround by abusing the [[doku>wiki:tpl:ach|ACH-Template]]:
+<code php>
+      <?php
+        ob_start();
+        tpl_content();
+        $myhtml = ob_get_contents();
+        ob_end_clean();
+        echo wfModiOut('screen', $myhtml);
+       ?>
+</code>
+Here ''wfModiOut()'' is a function, that consists mostly of those two lines:
+<code php>
+      $retval = str_replace('&ldquo;', '&raquo;', $retval);
+      $retval = str_replace('&rdquo;', '&laquo;', $retval);
+</code>
+I thought that a renderer plugin would replace this, and so I started to work around my workaround by the following code:
+<code php>
+<?php
+/**
+    MODIfied RENDerer for XHTML output
+    @license    GPL 2 (http://www.gnu.org/licenses/gpl.html)
+    @author Werner Flamme \<w.flamme@web.de>
+**/
+// the following lines are stolen from the s5 plugin of Harry Fuecks and Andi Gohr
+// must be run within Dokuwiki
+if(!defined('DOKU_INC')) die();
+// we inherit from the XHTML renderer instead directly of the base renderer
+require_once DOKU_INC.'inc/parser/xhtml.php';
+// stolen code ends here
+if (!defined('DOKU_PLUGIN'))
+  define('DOKU_PLUGIN', DOKU_INC . 'lib/plugins/');
+require_once DOKU_PLUGIN . 'modirend/conf/default.php';
+/**

+    something I always wanted but what never got implemented.

+class Doku_Renderer_modirend extends Doku_Renderer_xhtml {

+So I use the standard XHTML renderer of DokuWiki and overwrite 4 of its methods. When I append ''&do=export_modirend'' to the URL, I get "my" quotation marks (or when I use ''echo exportlink($ID, 'modirend');'' inside my template). This is the theory.
+Practically, the ''&do=export_modirend'' leads to displaying the document's content only, without any XHTML headers and other things that make a page look nice ;-). Without my quotation marks. When I add some output to ''$conf[...]'', this additional Text appears.
+Next, my Apache didn't show my pages correctly at all -- only fragments of them were shown, whether or not I added ''&do=export_modirend''. In the error log I only saw that Apache's child died unexpectedly (does Apache expect that the children die otherwise? ;-))
+Question: why don't I get the expected result -- a text (or a page) looking exactly like the other one, except for the modified quotation marks? How can I use the renderer plugin correctly?
