# Notes:
#   There are two ways to get the radar map:
#     - parse the link http://www.weather.com/outlook/travel/businesstraveler/map/<zip>?from=LAPmaps&bypassredirect=true
#     - look in the http://cgi.weather.com/looper/archive/ directory for the latest image
#
# Todo:
#   - i18n support

# activate:
