apt-rpm

I'm reading through the instructions of apt and I like it very much. It is
going (I think) to be much easier than RPMs.
There is even an apt-rpm which I think (no entry in man or info) simulates an
rpm to download rpms (can anyone back me up on that). (who can tell me how to
use apt-rpm) (kov@debian.org would also like those instructions to put into
the debian manual)
