Any modern presentation package. I use foils just because it's very
simple and robust. However, state of the art is powerdot (which was
created because prosper, which was based on seminar, was impossible to
make robust/improve) or beamer. (Both beamer and powerdot supports
there own stepwise display making texpower more or less unnecessary -
I haven't tested.)

The \rexxx functions are very simple in nature. They just add a step
without incrementing the step counter. However, predicting the effect
is sometimes very hard. I can ensure you that the result is correct,
but I agree that it some times is counter-intuitive.

(I didn't write or design the stepwise environment and it's functions,
so don't blame me or give me any credit - it's all Stephan Lehmke's
work.)
