# Script for syncing notes with iPod

# Usage:
# 
# sync-notes.sh [-i <ipod mountpoint>] [-d <path to folder containing notes (~/ipod_notes by default)>]
#           ...        [-e <encoding>]
#
# with the following defaults: 

IPOD_MOUNT=/media/ipod            # mountpoint of ipod
NOTESPATH=~/Desktop/notes         # path to folder containing notes
ENCODING=ISO-8859-15              # encoding used by ipod

# Unless called with "-e=none" this script requires "iconv" available
# from http://www.gnu.org/software/libiconv/

# About the encoding used by the iPod (by Jorg Schuler):
#
# For some reason the encoding used for the contact files and
# calenader 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


# Changelog:
#
# 2004/06/27 (Jorg Schuler <jcsjcs at users dot sourceforge dot net>):
# Changed to accept ipod-mountpath and encoding as command line
# option
#
# Split into two files -- one for contacts, one for calendar.
#
# Placed under GPL in agreement with Markus Gaugusch.
#
# Added note about encoding used by the iPod.
#
# 2004/07/02 (Jorg Schuler <jcsjcs at users dot sourceforge dot net>):
# Added Usage-line, added check for vcard file, rearranged source
#
# 2004/07/03 (Jorg Schuler <jcsjcs at users dot sourceforge dot net>):
# Made "iconv" optional (call with "-e=none")
#
# Removed "dos2unix" as my iPod (firmware 1.3) happily accepted
# DOS-type vcards as well. Instead changed the "grep" pattern to
# catch \cr\lf as well.
#
# 2004/12/15 (Clinton Gormley <clint at traveljury dot com>):
# adapted sync-korganiser to synchronise a folder containing notes
#
# 2005/04/02 (Thomas Perl <thp at perli dot net>):
# * added features to remove gedit backup files (*~) from source 
#   folder before syncing, better would be to modify the find 
#   command to exclude such backup files instead of deleting them
# * added support for directories inside of notes, syncing only 
#   directories containing files
# * added check to see if recode is installed
# 
# 2005/06/12 (Jorg Schuler <jcsjcs at users dot sourceforge dot net>):
# * added patch by Alexey Dokuchaev to replace recode by iconv
# * changed check for recode to check of iconv
#
# 2007/05/31 (Jorg Schuler <jcsjcs at users dot sourceforge dot net>):
# Corrections By Oliver Sherouse <oliver.sherouse AT gmail DOT com>
# (replaced some arithmetic expressions), fixed "-e=none", correctly
# indicate "-d" in 'usage' instead of "-p")


# overwrite default settings with optional command line arguments
