# Generates driving directions from a starting location
# to a series of destinations in a CSV, used to print
# maps for volunteers delivering food to the less-fortunate
#
# CSV format - place in a file named `list.csv`
# Name, Street, Zipcode, Phone, Count
#
# Generates two output folders:
# maps/ : Printer-friendly HTML directions with turn-by-turn images
# static/ : Images used in the maps

# Requirements: Python 2.5+ and jinja2
