# PRINT TO KINDLE in Mac OSX (for Kindle DX)
#
# HUH?
# - Kindle file depository:
# - drag any supported Kindle file to a local folder
# - file will be automatically transfered whenever Kindle is connected
# - "Print To Kindle" Print menu option (PDF):
# - when Kindle is connected it will print as PDF straight to the Kindle (from anywhere)
# - when Kindle is not connected, it will print to the local folder and is transfered as soon as Kindle is connected
# SETUP:
# 1. Create a local Kindle folder. Default is:
# ~/Desktop/Kindle
#
# 2. Set your CONFIGURATION options below
#
# 3. Save as .kindle_export.rb to your home folder
#
# 4. Set up a cron job (if you want automatic transfers):
# crontab -e
# */5 * * * * ruby ~/.kindle_export.rb >/dev/null 2>&1
#
# 5. Download the "Print to Kindle" Automator action at:
# http://www.feldpost.com/mementos/assets/print_to_kindle.zip
#
# 6. Unzip and drag Automator action to:
# ~/Library/PDF Services
#
# TODO:
#
# If a file is unsupported by the Kindle, it should be automatically emailed
# to the free Kindle conversion service.
