This genie will rearrange a document designed as double-page spreads to fit on the sheets of a simple stapled booklet. In this document, the first page has the first page on the right and the last on the left; the rest have pairs in normal order (2 & 3, 4 & 5, etc). It only works for Postscript output (which may be to a non-Postscript printer via Post). The pages are arranged so you can print the first half of the document on one side of the paper and then turn the paper over for the other half.
