The idea is pretty simple: Currently rpm triggers just work
on package names. If they would also consider the "Provides"
of a package, we could change rpm's find-provides script
so that it automatically adds a

    Provides: trigger(gtk-update-icon-cache)

if the filelist contains an icon.

Now, some other package would contain a trigger scriptlet that
triggers on "trigger(gtk-update-icon-cache)", this scriptlet
then would call the gtk-update-icon-cache application.

The advantage is that packagers don't need to put scriptlets
in their package, thus mistakes are reduced.

Triggers could also be used for other things which currently
are done by scriptlets, e.g.

- run ldconfig
- add a new user/group
- index "info" documentation
- make multimedia plugins available

In short, we want to get rid of most scriptlets.

Now, whether there will be "transaction" or "one-shot" triggers,
that's still to be discussed.

Cheers,
  Michael.
