["Jon A. Solworth" <solworth cs uic edu>]

        I would like to have a diagram which becomes visible, gradually in a
series of steps.  For example, I cover cryptographic
network protocols in my security course, and I'd like to have each
message appear separately on my slides.

        Is there some way of doing this that does not require the
drawing of multiple figures?

        It would seem to me that layers is closest to what I need,
but is there some way of outputing just the layers I need?
