# This is my Facebook application for BinaryAttraction. It should be quick and
# easy to deal with. It has a simple interface into Facebook so that people
# can play with the application in Facebook. I do not plan on adding all of the
# features from the webapp into the Facebook application. Sorry. Get a life and
# log in like the rest of ... everyone.
#
# Supports:
# * hall of fame!
# * voting
# * adding facebook photos
# * checking stats
# * inviting your friends!
