GnomeGuru was an attempt to
implement a "wizard" widget (a series of pages
representing steps in a task that the user can step
through). It is an immature interface and should not be
used; at press time, it appears that a new widget
called GnomeDruid will
replace it in the next version of Gnome. GnomeDruide will most likely be
available as an add-on module before that, so look for
it if you need a wizard widget.
