Themes (and menus) question

[John Williams <jwilliams business otago ac nz>]

Hi all

I am trying to find out how to change themes.  The information I have
found says to use the "Applications" menu on gnome-panel and go to
"Preferences->Theme".

I have no such menu structure.  (I have the "Preferences" sub menu but
no "Theme" item.)  I have read the documents about the menus being
created by gnome-vfs vfolders  in /etc and ~/.gnome2 but I cannot see
which RPM owns 

/etc/gnome-vfs-2.0/vfolders/applications.vfolder-info


which seems to be responsible for the "stock" Shrike menu. (rpm -qf
claims that it is not owned by any package.)

I am now lost.  Can anyone help?
