+      # Connect with Failover supports specifying multiple AMQP servers and configurations.
+      # 
+      # Argument Examples:
+      #   - "amqp://guest:guest@host:5672,amqp://guest:guest@host:5673"
+      #   - ["amqp://guest:guest@host:5672", "amqp://guest:guest@host:5673"]
+      #   - [{:host => "host", :port => 5672}, {:host => "host", :port => 5673}]
+      #   - {:hosts => ["amqp://user:pass@host:5672", "amqp://user:pass@host:5673"]}
+      #   - {:hosts => [{:host => "host", :port => 5672}, {:host => "host", :port => 5673}]}
+      #
+      # The last two examples are by far the most flexible, cause they also let you specify
+      # failover and fallback specific options. Like so:
+      #   - {:hosts => ["amqp://localhost:5672"], :fallback => false}
+      # 
+      # Available failover options are:
+      #   - :retry_timeout, time to wait before retrying a specific AMQP config after failure.
+      #   - :fallback, monitor for original server's return and fallback to it if so.
+      #   - :fallback_interval, seconds between each check for original server if :fallback is true.
