+files for booklet printing.  The resulting files need to be printed in
+landscape/long edge double sided printing.  The default paper format depends
+on the locale and is chosen by @code{pdfjam}.  It can be chosen using the
+@code{--paper} option.  Before the PDF is composed, the input file is cropped
+to the relevant area in order to discard unnecessary white spaces.  In this
+process, all pages are cropped to the same dimensions.  Extra margins can be
+defined at the edges of the booklet and in the middle where the binding
+occurs.")
