# iphotocleanup.sh
# Quick and dirty script by Stephanie Troeth
#
# Description: 
# This script may help you if you have different versions of iPhoto 
# Libraries and want to consolidate them. iPhoto doesn't know how to 
# do it cleanly, so we have to do some cleaning up on the iPhoto Library
# you wish to import.
# 
# You need to download two files before you can use the second part
# of this script. These files are:
# http://home.cfl.rr.com/genecash/digital_camera/EXIF.py
# http://home.cfl.rr.com/genecash/digital_camera/exiftool
# I have put them in a directory called 'bin' in my home directory.
# If you choose to put them elsewhere, make sure the python command
# below calls 'exiftool' from the right place.
# 
# Questions, suggestions, complaints to steph@unadorned.org
