-   This is an convinience wrapper around the ewiki PowerSearch page. It
-   should be used to catch 404 errors ("page not found") and let the
-   wiki try to find the correct page.
-
-   To set it up, link this wrapper (or move it) to the docroot or where your
-   ewiki wrapper script is located. Then edit the .htaccess and add
-   following (for Apache webservers):
-
-          ErrorDocument  404  404finder.php
-   
-   This wrapper should then call your ewiki wrapper/layout script, this is
-   what the $include variable is for:
-*/
-
-$include = "example-1.php";
