# This script parses the Master-Index.xml file, using the ifarchivexml
# module. (ifarchivexml.py must be in the current directory, or in your
# Python path.)
#
# Two handy ways to use this:
#
#   python -i parse-ifarchive.py Master-Index.xml
#
# Starts Python in interactive mode, with rootdir set to the root directory,
# dirs set to a dictionary of directories, and files set to a dictionary
# of files.
#
#   python parse-ifarchive.py Master-Index.xml Master-Index.pik
#
# Creates a pickle file containing the pickled tuple (rootdir, dirs, files).
# This can then be loaded with the Python commands:
#   import pickle
#   fl = open('Master-Index.pik', 'r')
#   (rootdir, dirs, files) = pickle.load(fl)
#   fl.close()
#
