Any further info you need?

The papersize header, I can just ignore. At some point I may add an
option to make a red line around the "paper," but...

What format does preview-test.1 have? Apparently the inclusion is PSFILE=preview-test.1, but it seems that gs does not handle it
gracefully, or needs some extra info to do the right thing.
