Upgrading Xemacs packages

[Frodo Baggins <thehobbit@altern.org>]

Hi debianers,
  I'd like to upgrade some of the lisp packages shipped with potato's
XEmacs to their more recent version from http://www.xemacs.org Is
there any "standard" procedure to do it in debian in order not to
break the file structure?

Thanks for your help.
