>From what I recall from the Fedora packaging guidelines, your need to
provide a tetex-a.b-c where c is one higher than the currently latest
existing version. This however works only as long as no new Tetex versions
appear. For a situation where you want to override a living package in the
distrubution I don't see how an obsoletes could reliably work. A conflict
sounds less tricky to me
