# This is a quick and dirty script to watch the petition, and back off when there's failures
# It also tries to resync back to checking once every 5 minutes.
# It also logs the data
# There's some hardcoded stuff. Deal with it.

# Accessing the json feed for this data is likely to be less disruptive.
