Using pager

[Allan Duncan <amd2345 fastmail com au>]

I've installed sawfish-pager-0.7, but can't work out how to invoke it.
At the moment I'm using Fedora 10 with gnome 2.24, and the Workspace
Switcher that comes with that runs the viewports nicely, but I wanted
to try old faithfull.

Also, can anyone suggest how to make sawfish the default global wm?
I can set it up on a per-user basis using gconf-editor (get it from
the forthcoming F11 binaries, no need to compile it), but can't see
how to tweak the gconf files in /etc
