This is the old ROX web-site. Please use the new website instead.
ROX-Filer is in Debian/stable. To install:
# apt-get install rox-filer
You can get all the other ROX software using Add App or Zero Install.
You can find major information about the ROX-in-Debian Project at 
http://alioth.debian.org/projects/pkg-rox/.
Before you start, you'll need to make sure a few extra packages are installed, using this command (as root):
# apt-get install dbus-1-dev dbus-glib-1 python2.3-dbus gnupg wget libexpat-dev xterm dbus-1 dbus-1-utils # apt-get install kernel-headers-2.4.25-1-386
The second line fetches the kernel headers for the 2.4.25 kernel. Change this to whatever version you are currently running. uname -a will display this information.
Then, follow the install-from-source instructions at http://0install.net/install.html.
Once that's done, set it to run on boot:
# update-rc.d 0install defaults
See the Zero Install page for instructions on how to start ROX from here.
You can install gtk themes w/ apt too.
apt-cache search gtk-engines apt-cache search gtk2-engines
Then just select a theme from the GTk theme switcher or by runing ROX-session>SessionSetting>Display
After installing, you might like to read the Getting Started Guide.
