[xwiki-users] Macro for "related pages" or "sons pages" or "see also"

Hi, Is there a Macro/Extension/Solution for Xwiki similar to the one used in Wikipedia, I am thinking of some tool that allows a page to have son pages (tree hierarchy if possible) and to list them automatically, like the "see also" feature in wikipedia, or "related articles" Does that make sense ? or is it done manually in wikipedia ? Best Regards, -- *BHY*
