Usage[]
Include this on a subpage that has the same name as the category you wish to list. All pages in that category are then linked and thus un-orphaned.
The page that contains this template is placed in Category:Orphaned articles lists.
Example[]
Writing {{List orphans}} on GuildWiki:Non-orphaned_articles/Subpages makes all articles in Category:Subpages unorphaned.
Technical Note[]
The template uses DPL and not categorytree because the latter is throttled to 200 items by default.
