I'd like to have as simple API as possible. Something like Steffen
Nurpmeso's. I need groff only to typeset two diversions and place them
properly (I've already got the placement part quite right) according to
the paper size defined in the command line (-dpaper=c5l -P-pc5
-P-l). The content of the diversions is going to be assembled either
"manually" (say, I've got a single envelope to print) or by a properly
crafted script that reads a database.

These are the bits I haven't known that somehow prevented me from
thinking about multiple (and variable number of) parameters.

Or maybe yours looks even better.

It sure does. Thanks a lot.
