# Script for syncing Palm addressbook data with iPod via Jppy
# (c) 2005 Nick Piper <nick at nickpiper dot co dot uk>
#

# Usage:
# 
# sync-jppy.py [-i <ipod mountpoint>] [-e <encoding>]
#
#
# with the following defaults: 

IPOD_MOUNT="/media/ipod"         # mountpoint of ipod
ENCODING="ISO-8859-15"         # encoding used by ipod

# Unless called with "-e=none" this script requires "recode" available
# from ftp://ftp.iro.umontreal.ca/pub/recode/recode-3.6.tar.gz

# About the encoding used by the iPod (by Jorg Schuler):
#
# For some reason the encoding used for the contact files and
# calender files depends on the language you have set your iPod
# to. If you set your iPod to German, iso-8859-15 (or -1?) is
# expected. If you set it to Japanese, SHIFT-JIS is expected. You need
# to reboot the iPod to have the change take effect, however. (I'm
# using firmware version 1.3.)
#
# If you know of more encodings, please let me know, so they can be
# added here:
#
# iPod language      encoding expected
# ----------------------------------------
# German             ISO-8859-15
# Japanese           SHIFT-JIS
