I just made some changes to allow creation of a debian package. I tarballed them here: http://alf.hopto.org/denu/additional.tgz
The package is completely untested, since I haven't really grokked what denu *does* yet : ) I'll maybe get around to that later this week; classes and all.
Just cd to the top of your denu source, untar that thing, and type "make deb" to make a debian package. (Requires you to have a debian system, or at least the debian packaging tools)
