Extension:LinkSearch

What can this extension do?
This extension adds a special page Special:Linksearch which allows to search for pages that contain external link. The external link can be specified by general searchpatterns like "*.wikipedia.org".

Installation
Make a new folder in your extension directory: LinkSearch, save the files from subversion.

Add the following lines to your LocalSettings.php:

//Extension LinkSearch require_once("$IP/extensions/LinkSearch/LinkSearch.php");

Known Bugs
In some installations the page Special:Linksearch will not appear. This has not been resolved.

In my case I could make it work by placing the require_once call not near the end of LocalSettings.php, but before all other extensions are called.

Sites
This extension is installed on Wikimedia sites.
