[Mediawiki-l] What templates are used?

[Gunter]

When you edit an article, below the edit window is a list of all used 
templates. In some cases we restrict edit rights on a page, thus the 
user can not see the used template list.

I would like to provide a link in the toolbox section below "what links 
here": "what templates are used" that gives the list of the templates 
for the current article.

How can I do that?

regards,
Gunter
