Extension:IndexFunction

Usage
To use the extension, tag pages with, where "Index1," "Index1", etc. are the titles you wish to index the current page as. (Think of the index in a book, which may contain For X see Y). This will cause Index1 and Index1 to automatically redirect to the page from links and searches. Multiple pages can share the same indexes, instead of redirecting to the page, the titles will redirect to an automatically generated disambiguation page. The page will sort the articles into headings based on the categories that the pages are in.

Titles used as indexes have a couple restrictions - they cannot also exist as pages (if a page is created at the same title as an index, the index will be deleted from the database) and they must be valid page titles.

The appearance of internal links to index titles can be customized using CSS, all links will contain the "mw-index" class.
