# pdf2pocketmod - script to generate 1-page pocketmod from 8-page pdf.
# Little Neo, 2011

# very very very inspired by Rick Holbert
# http://weblog.bignerdranch.com/?p=23 (see comments)

# The script works with A4 paper. If you want to use US letter paper, replace the word a4paper with letterpaper.

# use: ./pdf2tinybk foo.pdf
# will generate foo_pocketmod.pdf

# Enjoy!
