rearranges pages from a PostScript document into ``signatures'' for
printing books or booklets, creating a new PostScript file. The
input PostScript file should follow the Adobe Document Structuring
option selects the size of signature which will be used. The signature size is
the number of sides which will be folded and bound together; the number given
should be a multiple of four. The default is to use one signature for the
whole file. Extra blank sides will be added if the file does not contain a
multiple of four pages.
Psbook normally prints the page numbers of the pages rearranged; the
option suppresses this.
