I've added the RPM for 0.44 to the Zero Install interface file. I've put up a copy here:
http://0install.net/tests/Inkscape.xml
Run this way, the RPM works on Debian/unstable, Debian/testing and Ubuntu/5.10 (if you have libglitz, libstdc++6, libgtkspell0, libgnomevfs2-0 and libxslt1.1 installed). It does not work on Debian/sarge (due to a (bogus?) dependency on pangocairo).
If you'd like to host this on the inkscape.org site, the steps are:
1. Download the XML above:
$ wget http://0install.net/tests/Inkscape.xml
2. Get 0publish (if you don't have it already):
$ 0alias 0publish http://0install.net/2006/interfaces/0publish
3. Set the URI to the address on the inkscape site where it will be made available, and resign with your GPG key:
$ 0publish Inkscape.xml \ --set-interface-uri=http://inkscape.org/2006/Inkscape.xml \ --key=Jean
4. This will also create a .gpg file with your public key. Upload both to the same directory on the web-server.
People will then be able to install it using:
$ 0alias inkscape http://inkscape.org/2006/Inkscape.xml
or by dragging to their GUI installer.
Thanks,
