Dome times I have to deal with XPS files (XPS is a Microsoft's rival to Adobe's PDF format, technically a zipped XAML (XML)). Can I view them in Ubuntu? Or, maybe, I could even produce them?
Okular, the KDE pdf viewer, supports XPS. The package name is
okular I'm not aware of any GNOME/GTK+ viewers that support XPS, though according to this evince bug in upstream GNOME support has been added. It's not working for me in Maverick....
Frank comment : sudo aptitude install Okular
