DESCRIPTION

Create print-ready PDF files from some INPUT PDF 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 choosen by
pdfjam. It can be set with the --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.

The OUTPUT is written to INPUT-book.pdf. Existing files will be overwritten.
All input files are processed seperatly.

EXAMPLES

To simply create a booklet from input.pdf you can use

    pdfbook2 input.pdf

to create input-book.pdf. To select a special type of paper you can do

    pdfbook2 --paper=letter input.pdf

for letter or

    pdfbook2 --paper=a4paper input.pdf

for standard A4. To increase the inner margin for binding use

    pdfbook2 --inner-margin=200 input.pdf

to increase the default value of 150. You can submit multiple files to the 
script for processing like

    pdfbook2 input1.pdf input2.pdf

which will result in input1-book.pdf and input2-book.pdf.
