;;; Commentary:
;;;
;;; Generate a package declaration template for the latest version of a
;;; package on CTAN, using the XML output produced by the XML API to the CTAN
;;; database at http://www.ctan.org/xml/1.2/
;;;
;;; Instead of taking the packages from CTAN, however, we fetch the sources
;;; from the SVN repository of the Texlive project. We do this because CTAN
;;; only keeps a single version of each package whereas we can access any
;;; version via SVN. Unfortunately, this means that the importer is really
;;; just a Texlive importer, not a generic CTAN importer.
