# 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
