 That is why ppower4 is such a nice alternative:  It inserts just some
pdf comments and otherwise leaves the typesetting alone.  Then a
postprocessor takes the pdf file and creates a new one, with everything
left at its original position, but appearing only on the pages (a slide
is built up by jumping to the next page) where it is supposed to appear.

 Well, a general solution for the isolated requiement of “having
considered content, audience and everything, I want my text/gfx/
whatever appear step-wise“ would be a good thing, imho.  And I did in
the past also use things like removing the full stop when stepping from

   This implies A and therefore, B.


 I have also seen a presentation where the speaker sketched a proof of
some lemma, then generelized it and simply exchanged the relevant words
in the lemma.  The new words were shorter, so there was some space to
the left and right of them and they had some contrast color.  The effect
was not just “cool” and “I don't think Powerpoint could do that” –
what's more important is that this was by far the clearest way of
getting the message across.


 Is there a way of having \installprogram for only for after the *last*
run?  (I don't think there could be a systemmode for the last run, but
texexec knows it has done the last run, so there might be some file.tui
line doing this kind of magic.)
