PDF

We need to be able to export MediaWiki categories as PDF books for printing. We had this functionality in XmlWiki using the pdf-export.php code, but this now needs to be made into a standard MediaWiki extension, probably a special page. It seems a waste to make another pdf export when MW:Extension:Pdf Export is already available, so adding the old XmlWiki category book-building code to the existing one may be the better option, especially since their code is directly editable from the extension article.
