#
# A Dispatcher implementation that uses hot_bunnies, a JRuby AMQP client using the
# Java client for RabbitMQ. This class can be loaded if hot_bunnies is not
# available, but it will fail upon initialization. If you want to use this
# runner (it's currently the only one that works very well), make sure to
# add
#
#   gem 'hot_bunnies'
#
# to your Gemfile.
